[0033] The base 11 is arranged on the installation surface of the printer 100. The base 11 supports various components of the printer 100, such as the medium supporting mechanism 30 and the driving mechanism 50. Figure 2 The base portion 11 shown includes a first base member 11a, a second base member 11b, and a main body pulley 13. The first base member 11a and the second base member 11b are arranged side by side along the Y axis.

[0034] The medium supporting mechanism 30 supports the printing medium M. The medium supporting mechanism 30 adjusts the printing medium height along the Z axis of the supported printing medium M. The medium supporting mechanism 30 includes a stage 31 and a height moving mechanism 32 .

[0035] The table 31 is configured to be able to place a printing medium M. The printing medium M is placed on the table 31. The table 31 is a table that does not move along the X-axis and the Y-axis. The table 31 includes a medium support portion 31m and a table leg portion 31n.

[0036] The medium support unit 31m is a component that supports the print medium M. The medium support unit 31m is a rectangular flat plate. The print medium M is placed on the medium support surface 31s of the medium support unit 31m. The medium support surface 31s is the surface of the medium support unit 31m in the +Z direction. The support surface length W of the medium support surface 31s along the X-axis is equal to or approximately equal to the length of the maximum-sized print medium M along the X-axis. The length of the medium support surface 31s along the Y-axis can be longer or shorter than the length of the maximum-sized print medium M along the Y-axis.

[0037] The table legs 31n support the medium support portion 31m. Figure 2 The table 31 shown has a plurality of table legs 31n. The plurality of table legs 31n are arranged at the ends of the medium supporting portion 31m. The number and position of the table legs 31n can be set as appropriate.

[0038] The height moving mechanism 32 moves the medium support portion 31 m along the Z axis. The height moving mechanism 32 adjusts the height of the print medium M placed on the medium support portion 31 m. The height moving mechanism 32 includes a lifting motor 33 , a lifting belt 37 , and a plurality of lifting mechanisms 39 .

[0039] The lift motor 33 generates a driving force to move the table 31 along the Z-axis. The lift motor 33 has an output shaft (not shown). The output shaft of the lift motor 33 rotates in a direction to move the table 31 in the +Z direction or in a direction to move the table 31 in the -Z direction. The printer 100 moves the table 31 in the +Z direction or the -Z direction by operating the lift motor 33.

[0040] The lifting belt 37 is an endless belt that is stretched over the output shaft of the lifting motor 33 and the plurality of lifting mechanisms 39. The lifting belt 37 is driven to circulate by the rotation of the output shaft of the lifting motor 33. The lifting belt 37 transmits the rotation of the output shaft of the lifting motor 33 to the plurality of lifting mechanisms 39.

[0041] The lifting mechanism 39 moves the workbench 31 along the Z-axis. The lifting mechanism 39 is provided on each of the plurality of workbench legs 31n. As an example, the lifting mechanism 39 is composed of a ball screw, a nut, and a lifting pulley. The ball screw, the nut, and the lifting pulley are not shown in the figure. The ball screw is arranged along the Z-axis. The ball screw is supported on the base portion 11 in a rotatable manner. The nut is screwed with the ball screw. The nut is fixed to the workbench leg 31n. The lifting pulley is fixed to the upper part of the ball screw. The lifting pulley is engaged with the lifting belt 37. The lifting pulley transmits the rotation of the output shaft of the lifting motor 33 via the lifting belt 37. When the lifting pulley rotates, the ball screw rotates. The rotation of the ball screw causes the nut and the workbench leg 31n to move along the Z-axis.

[0042] The drive mechanism 50 moves the moving portion 70 along the Y-axis. The drive mechanism 50 includes a first guide shaft 51 a , a second guide shaft 51 b , and a frame drive portion 60 .

[0044] The frame driving unit 60 includes a frame moving motor 61, a driving belt 63, a speed change mechanism 65, and a transmission belt 67. Figure 2 The frame driving unit 60 is shown as being arranged at a position in the -X direction of the base unit 11 , but may be arranged at a position in the +X direction. Preferably, the frame driving unit 60 is arranged at a position in the -X direction.

[0045] The frame moving motor 61 generates a driving force that moves the moving unit 70 along the Y-axis. The frame moving motor 61 has a rotation shaft 61a. The rotation shaft 61a of the frame moving motor 61 rotates in a direction that moves the moving unit 70 in the +Y direction or in a direction that moves the moving unit 70 in the -Y direction. The printer 100 moves the moving unit 70 in the +Y direction or the -Y direction by operating the frame moving motor 61.

[0046] The drive belt 63 transmits the driving force generated by the frame moving motor 61 to the speed change mechanism 65 . The drive belt 63 is an endless belt stretched between the rotating shaft 61 a of the frame moving motor 61 and the speed change mechanism 65 .

[0047] The speed change mechanism 65 changes the speed of the rotation based on the rotating shaft 61a. The speed change mechanism 65 includes, for example, a first pulley and a second pulley. Details of the first pulley and the second pulley are not shown. The first pulley is wound around the drive belt 63. The second pulley is wound around the transmission belt 67. The speed change mechanism 65 rotates the second pulley by transmitting the driving force from the drive belt 63 to the first pulley. The second pulley drives the transmission belt 67. The speed change mechanism 65 transmits the driving force of the frame moving motor 61 to the transmission belt 67 according to a reduction ratio corresponding to the ratio of the diameters of the first pulley and the second pulley.

[0048] The transmission belt 67 transmits the driving force to the moving portion 70. The transmission belt 67 is an endless belt that is stretched between the speed change mechanism 65 and the main pulley 13. The main pulley 13 is arranged on the second base member 11b.

The first leg 73a is secured to the transmission belt 67 via the first belt connection portion 79a. When the transmission belt 67 is driven in a circular motion, the first leg 73a transmits driving force via the first belt connection portion 79a. The movable portion 70 moves along the Y-axis by the driving force transmitted to the first leg 73a.

[0053] The second leg 73b is disposed at a position in the +X direction of the main frame 71. The second leg 73b is engaged with the second guide shaft 51b. The second leg 73b is guided by the second guide shaft 51b. The second leg 73b is movable in the +Y direction and the -Y direction along the second guide shaft 51b.

[0054] The carriage support frame 81 supports a carriage 91 to be described later. The carriage support frame 81 is a plate-shaped member disposed along the X-axis. The carriage support frame 81 is supported by the main frame 71.

[0055] The carriage drive motor 82 generates a drive force for moving the carriage 91 . The carriage drive motor 82 is supported by the carriage support frame 81 . Figure 2 The carriage drive motor 82 shown is arranged at a position in the −X direction of the carriage support frame 81 .

[0056] The transmission mechanism 83 transmits the driving force generated by the carriage drive motor 82 to the carriage drive belt 85. The transmission mechanism 83 includes a transmission pulley 83a, a secondary transmission pulley 83b, and a transmission belt 83c. The transmission pulley 83a is fixed to the drive shaft of the carriage drive motor 82. The transmission belt 83c is an endless belt stretched over the transmission pulley 83a and the secondary transmission pulley 83b. The secondary transmission pulley 83b includes a small pulley and a large pulley with a larger diameter than the small pulley. The large pulley is wound around the transmission belt 83c. The small pulley is wound around the carriage drive belt 85. The transmission belt 83c is driven to circulate by the rotation of the carriage drive motor 82. The transmission belt 83c rotates the large pulley. The rotation of the large pulley by the transmission belt 83c rotates the small pulley. The small pulley drives the carriage drive belt 85 to circulate. The rotation of the carriage drive motor 82 is transmitted to the carriage drive belt 85 at a reduction ratio corresponding to the ratio between the diameters of the large pulley and the small pulley.

[0057] The carriage guide shaft 84 guides the carriage 91. The carriage guide shaft 84 is fixed to the carriage support frame 81. The carriage guide shaft 84 is arranged along the X-axis. The carriage guide shaft 84 guides the carriage 91 along the X-axis.

[0058] The carriage drive belt 85 moves the carriage 91. The carriage drive belt 85 is an endless belt that is stretched across the transmission mechanism 83 and a carriage drive pulley (not shown). The transmission mechanism 83 is located at the -X direction relative to the carriage support frame 81. The carriage drive pulley is located at the +X direction relative to the carriage support frame 81. The carriage drive belt 85 is arranged along the carriage guide shaft 84.

[0059] The printer 100 may also include a height detection unit 88. The height detection unit 88 detects the height of the print medium M placed on the worktable 31. The height detection unit 88 includes a contact plate 89 that protrudes downward from the lower end of the main frame 71. The contact plate 89 is a plate-shaped component. It is mounted relative to the main frame 71 so that it can rotate about a virtual rotation axis parallel to the X-axis. The contact plate 89 rotates when it contacts the print medium M or the medium support 31m. An arm (not shown) is formed on the contact plate 89. The arm displaces as the contact plate 89 rotates. The displacement of the arm is detected by a displacement sensor (not shown). The displacement sensor is provided on the height detection unit 88. The displacement sensor is a magnetic sensor, a reflective optical sensor, or a transmissive optical sensor. The displacement of the arm is detected by the displacement sensor, allowing the height detection unit 88 to detect the rotation of the contact plate 89. The height detection unit 88 detects the height of the print medium M by detecting the rotation of the contact plate 89.

[0060] The recording unit 90 prints on the print medium M. The recording unit 90 is supported by the moving unit 70 . The recording unit 90 includes a carriage 91 and a printing unit 93 .

[0061] The carriage 91 carries the printing unit 93. The carriage 91 is connected to the carriage drive belt 85. When the carriage drive belt 85 is driven in a circular motion, the carriage 91 moves. The carriage 91 is supported by the carriage guide shaft 84. The carriage 91 is movable along the carriage guide shaft 84. The carriage 91 is movable in the +X direction or the -X direction along the X-axis. The carriage 91 moves along the X-axis between an end position in the -X direction and an end position in the +X direction. The carriage drive belt 85 is driven by the carriage drive motor 82, thereby moving the carriage 91 between an end position in the -X direction and an end position in the +X direction.

[0062] The end position in the -X direction is indicated as the initial position. The initial position is a position different from the position on the printing medium M. The initial position is a position close to the -X direction or the +X direction relative to the printing medium M. Figure 2 In the illustrated printer 100, the initial position is the position in the -X direction of the print medium M and the medium support portion 31m supporting the print medium M. The carriage 91 in the initial position may be positioned opposite a maintenance mechanism that performs maintenance such as flushing or cleaning of the print unit 93. The maintenance mechanism is not shown. The maintenance mechanism is located at a position facing the carriage 91 in the initial position, or adjacent to the position. Figure 2 The recording section 90 at the initial position is shown by a dotted line.

[0063] The end position in the +X direction is the return position. The carriage 91 stops at the return position. The carriage 91 moves in the +X direction from the initial position. From the initial position, the carriage 91 passes over the print medium M and stops at the return position. The return position is a position closer in the +X direction to the initial position. After stopping at the return position, the carriage 91 moves in the -X direction. From the return position, the carriage 91 passes over the print medium M and moves to the initial position.

[0064] The printing unit 93 prints on the print medium M. The carriage 91 moves along the X-axis, thereby moving the printing unit 93 in the +X or -X direction. The main frame 71 moves along the Y-axis, thereby moving the printing unit 93 in the +Y or -Y direction. The printer 100 can move the printing unit 93 along the X-axis and the Y-axis relative to the table 31. The printing unit 93 can eject ink onto the entire print medium M supported on the table 31.

[0065] Figure 3 The cross-sectional structure of the printing unit 93 is shown. Figure 3 The printing unit 93 includes a print head unit 94 and a UV (Ultraviolet) lamp 96. The printing unit 93 includes a first UV lamp 96a, the print head unit 94, and a second UV lamp 96b in this order from the position in the -X direction along the X axis.

[0066] The print head unit 94 includes one or more print heads 95 . Figure 3 The print head unit 94 shown includes a first print head 95a, a second print head 95b, a third print head 95c, and a fourth print head 95d. Figure 3 The print head unit 94 shown includes four print heads 95 , but the present invention is not limited thereto. The print head unit 94 may include one or more print heads 95 . Preferably, the print head unit 94 includes a plurality of print heads 95 .

[0067] The print head 95 ejects liquid ink onto the print medium M. The print head 95 has multiple nozzles (not shown) for ejecting ink. The nozzles open on the -Z direction surface of the print head 95. When the print head 95 ejects ink from the nozzles, the ejected ink flies from the -Z direction surface of the print head 95 toward the print medium M placed on the stage 31. The ink lands on the print medium M.

[0068] The ink ejected from the print head 95 is an ultraviolet curing ink. The ultraviolet curing ink mainly contains a resin material, a photopolymerization initiator, and a solution.

[0069] The resin material is a material that forms a resin film. The resin material is liquid at room temperature. The resin material has crosslinkable groups. Preferably, the resin material is a material that can be polymerized. Preferably, the resin material is in the form of an oligomer. It is even more preferred if the resin material is in the form of a monomer.

[0070] The photopolymerization initiator functions as a curing agent. The photopolymerization initiator acts on the crosslinkable groups of the resin material to cause a crosslinking reaction. An example of a photopolymerization initiator is benzyl dimethyl ketal.

[0071] The solution is a solvent or dispersion medium. The solution adjusts the viscosity of the resin material. By adding the solution to the UV curable ink, the UV curable ink is adjusted to a predetermined viscosity.

[0072] UV-curable inks can also contain pigments and functional materials. These pigments impart inherent functionality to UV-curable inks. Pigments include pigments or dyes. Examples of pigments in UV-curable inks include cyan, magenta, yellow, and white. For example, the functional material is a surface-modifying material that imparts lyophilic or lyophobic properties.

[0073] The multiple print heads 95 each eject UV-curable ink onto the print medium M. Preferably, the print head unit 94 ejects multiple or more types of UV-curable ink onto the print medium M using the multiple print heads 95. The multiple inks may differ from one another in at least one of the resin material, photopolymerization initiator, and solution. The multiple inks may also differ in the pigments and functional materials added thereto.

[0074] The multiple UV-curable inks ejected by the print head unit 94 may also include a clear ink. Clear ink contains a photopolymerization initiator and a polymerizable compound. Clear ink is used to protect coatings formed with other inks or to adjust the gloss of printed materials. Preferably, the pigment content in the clear ink is 0.2% by mass or less relative to the total amount of the clear ink. More preferably, the clear ink contains no colorant.

[0075] As an example, the first print head 95a, the second print head 95b, the third print head 95c, and the fourth print head 95d each eject a different type of UV-curable ink. The first print head 95a ejects a cyan ink containing a cyan pigment. The second print head 95b ejects a magenta ink containing a magenta pigment. The third print head 95c ejects a transparent ink. The fourth print head 95d ejects a yellow ink containing a yellow pigment.

[0076] The UV lamp 96 cures the ultraviolet curable ink ejected onto the print medium M. UV stands for ultraviolet. The UV lamp 96 irradiates the print medium M with ultraviolet light. By irradiating the print medium M with ultraviolet light, the UV lamp 96 cures the ultraviolet curable ink ejected onto the print medium M.

[0077] The UV lamp 96 may be composed of a metal halide lamp, a xenon lamp, a carbon arc lamp, a chemical lamp, a low-pressure mercury lamp, a high-pressure mercury lamp, or the like. The UV lamp 96 may also be composed of an ultraviolet light emitting diode, an ultraviolet light emitting semiconductor laser, or the like. The UV lamp 96 emits ultraviolet light having a wavelength of 365 nm or more and 410 nm or less. The peak irradiation intensity of the UV lamp 96 is preferably 200 mW / cm 2 More than 800 mW / cm 2 above.

[0078] exist Figure 3 The printing unit 93 shown in FIG. 1 includes a first UV lamp 96a and a second UV lamp 96b as UV lamps 96. While the printing unit 93 includes the second UV lamp 96b, the present invention is not limited thereto. The printing unit 93 may also include the second UV lamp 96b. Preferably, the printing unit 93 includes the second UV lamp 96b.

[0079] The printing unit 93 can print Braille characters 400. The print head unit 94 ejects ultraviolet curing ink onto the print medium M. The print head unit 94 ejects ultraviolet curing ink onto the print medium M, thereby forming protrusions on the print medium M. These formed protrusions function as dots 403 of the Braille characters 400. The printer 100 can print Braille characters 400.

The number setting value is the total number of Braille patch images 411 that have one setting value that differs from each other but the same other setting values. For example, if the reference setting value group includes three setting values: diameter setting value, height setting value, and curvature radius setting value, the number setting value is the total number of Braille patch images 411 that have different diameter setting values but the same height setting value and curvature radius setting value. The number setting value sets the number of Braille patch images 411 included in the Braille test chart 410.

[0116] The confirm button icon 550 receives input from the user. The confirm button icon 550 receives input indicating that input into each setting field has been completed. After the user has input into each setting field displayed on the first braille pattern setting screen 500a, the user performs an input into the confirm button icon 550.

[0117] Although Figure 8The first braille pattern setting screen 500a shown includes a spacing setting column 530 and a patch number setting column 540, but the present invention is not limited thereto. The first braille pattern setting screen 500a may not include at least one of the spacing setting column 530 and the patch number setting column 540. Preferably, the first braille pattern setting screen 500a includes at least one of the spacing setting column 530 and the patch number setting column 540. By including at least one of the spacing setting column 530 and the patch number setting column 540, the user can generate a detailed braille test chart 410.

[0118] When the user performs an input operation on the decision button icon 550, the input unit 230 receives the setting values etc. inputted into the respective setting fields. The input unit 230 receives the reference point setting information and the Braille spacing information related to the respective setting values.

[0120] Braille spacing information is a set of adjustment values set in the first spacing setting field 530a. The adjustment value set includes at least one of a diameter adjustment value, a height adjustment value, and a curvature radius adjustment value. Braille spacing information corresponds to the difference between the reference parameter and the adjustment parameter. If the first Braille pattern setting screen 500a does not include the spacing setting field 530, the input unit 230 retrieves the predefined Braille spacing information from the storage unit 220. The storage unit 220 stores the predefined Braille spacing information in advance. Braille spacing information corresponds to an example of spacing information.

[0121] If the first braille pattern setting screen 500a includes a patch quantity setting field 540, the input unit 230 receives the number setting value. If the first braille pattern setting screen 500a does not include a patch quantity setting field 540, the input unit 230 retrieves the predefined number setting value from the storage unit 220.

[0122] The print control device 200 includes an input unit 230 for receiving reference point setting information for setting reference parameters. The reference point setting information includes at least one of a reference setting value group and a specification setting value.

[0123] The user can set the shape of the reference point 403a of the reference Braille patch image 411a included in the Braille test chart 410. The user can set Braille characters 400 of various specifications or arbitrary sizes as the reference Braille patch image 411a.

[0124] Preferably, the input unit 230 receives a number setting value for designating the number of the plurality of Braille patch images 411 included in the Braille test pattern 410 .

[0125] The user can adjust the number of Braille patch images 411 included in the Braille test chart 410 .

[0126] After receiving the reference dot setting information, the Braille character spacing information, and the number setting value, the input unit 230 transmits the reference dot setting information, the Braille character spacing information, and the number setting value to the data generating unit 253 .

[0127] The data generation unit 253 receives the reference dot setting information and the Braille spacing information as setting data. The data generation unit 253 uses the reference dot setting information, the Braille spacing information, and the number setting value to generate test pattern printing data. The test pattern printing data includes reference parameters and adjustment parameters. The data generation unit 253 generates the reference parameters and adjustment parameters.

[0128] The data generation unit 253 generates reference parameters using the reference point setting information. The data generation unit 253 determines whether the reference point setting information is at least one of a standard setting value and a reference setting value group.

[0129] When the data generation unit 253 determines that the reference point setting information is a specification setting value, it reads the specification value data set corresponding to the specification setting value from the storage unit 220. The specification value data set includes a diameter specification value, a height specification value, and a curvature radius specification value. The specification value data set is pre-stored in the storage unit 220. The data generation unit 253 generates reference parameters containing the specification value data. The diameter specification value, the height specification value, and the curvature radius specification value are generated by the data generation unit 253 as the reference parameters for the diameter setting value, the height setting value, and the curvature radius setting value, respectively.

[0130] When the data generating unit 253 determines that the reference point setting information is a reference setting value group, it generates reference parameters using the reference setting value group. The data generating unit 253 generates reference parameters including a diameter setting value, a height setting value, and a curvature radius setting value.

[0131] The data generation unit 253 can also convert the height setting value into the ink layer number setting value. Figure 6The data generation unit 253 generates a reference parameter including an ink layer number setting value instead of a height setting value. The ink layer number setting value indicates the number of ink layers 407 corresponding to the height setting value. The ink layer number setting value corresponds to an example of a first layer number setting value.

[0132] When the data generation unit 253 determines that the reference point setting information is a standard setting value and a reference setting value group, it reads the standard value data group corresponding to the standard setting value from the storage unit 220. The data generation unit 253 compares the reference setting value group with the standard value data group. The data generation unit 253 replaces the setting values included in the standard value data group that differ from the setting values included in the reference setting value group with the setting values included in the reference setting value group. The data generation unit 253 generates a revised reference setting value group. The data generation unit 253 generates reference parameters that include the revised reference setting value group.

[0133] After generating the reference parameter, the data generating unit 253 generates a plurality of adjustment parameters using the reference parameter, the interval information, and the number-specified value.

[0134] The data generation unit 253 determines the number of braille patch images 411 for each set value based on the number setting value. The braille test chart 410 consists of one reference braille patch image 411a and multiple adjustment braille patch images 411b. The data generation unit 253 uses the number setting value to determine the number of adjustment braille patch images 411b. If the number setting value is 3 and the set values are the diameter setting value, the height setting value, and the curvature radius setting value, the braille test chart 410 consists of 27 braille patch images 411. The braille test chart 410 consists of one reference braille patch image 411a and 26 adjustment braille patch images 411b.

[0135] The data generation unit 253 generates adjustment parameters corresponding to the multiple adjustment Braille patch images 411b. The data generation unit 253 generates the adjustment parameters using the reference parameters and the spacing information. If the reference parameters include a diameter setting value, a height setting value, and a curvature radius setting value, the data generation unit 253 generates the adjustment parameters using one of the diameter adjustment value, the height adjustment value, and the curvature radius adjustment value. The adjustment parameters include an adjustment diameter setting value, an adjustment height setting value, and an adjustment curvature radius setting value. The data generation unit 253 makes at least one of the adjustment diameter setting value, the adjustment height setting value, and the adjustment curvature radius setting value included in the adjustment parameters different from the diameter setting value, the height setting value, and the curvature radius setting value included in the reference parameters. The data generation unit 253 makes the reference parameters different from the adjustment parameters.

[0136] As an example, the data generation unit 253 makes the diameter adjustment value included in the adjustment parameter different from the diameter adjustment value included in the reference parameter. The data generation unit 253 generates the diameter adjustment value included in the adjustment parameter by adding or subtracting the diameter adjustment value from the diameter adjustment value included in the reference parameter. The data generation unit 253 generates the diameter adjustment value included in the adjustment parameter by adding or subtracting a multiple of the diameter adjustment value from the diameter adjustment value included in the reference parameter. The data generation unit 253 generates the height adjustment value and curvature radius adjustment value included in the adjustment parameter in a similar manner.

[0137] When the reference parameter includes an ink layer count setting value instead of a height setting value, the data generation unit 253 generates an adjustment parameter including an adjusted ink layer count setting value. The data generation unit 253 converts the height adjustment value into an ink layer count adjustment value. The ink layer count adjustment value is the number of ink layers 407 corresponding to the height adjustment value. The data generation unit 253 uses the ink layer count setting value and the ink layer count adjustment value to generate the adjusted ink layer count setting value. If the height adjustment value is set, the adjusted ink layer count setting value is different from the ink layer count setting value. The adjusted ink layer count setting value corresponds to an example of the second layer count setting value.

[0138] After generating print data including the reference parameters and the plurality of adjustment parameters, the data generation unit 253 transmits the Braille test pattern print data to the printer 100 via the communication control unit 255. The printer 100 receives the Braille test pattern print data and prints the Braille test pattern 410 based on the Braille test pattern print data.

[0139] After having the printer 100 print the Braille test chart 410, the print control device 200 receives a user's evaluation result of the Braille patch image 411. The user performs a designation input operation on the input device 310 to designate the desired Braille patch image 411. The input unit 230 inputs designation data corresponding to the designation input operation. The designation data includes patch designation information representing the desired Braille patch image 411. The input unit 230 transmits the designation data to the data generation unit 253. The data generation unit 253 uses the patch designation information to specify the Braille patch image 411. The data generation unit 253 causes the storage unit 220 to store Braille parameters for printing the specified Braille patch image 411. The Braille parameters are a reference parameter and one of a plurality of adjustment parameters. Upon receiving a print instruction to print the Braille patch 400, the print control device 200 generates print data including the Braille parameters. The print control device 200 causes the printer 100 to execute printing based on print data including Braille parameters.

[0140] The print control device 200 includes a data generation unit 253 for generating test chart print data, which causes the printer 100 to eject ink and print a braille test chart 410 composed of a plurality of braille patch images 411, including a reference braille patch image 411a and an adjustment braille patch image 411b, and a communication control unit 255 for transmitting the test chart print data to the printer 100. The data generation unit 253 causes the reference parameters associated with the reference points 403a included in the reference braille patch image 411a to differ from the adjustment parameters associated with the adjustment points 403b included in the adjustment braille patch image 411b.

[0141] When printing Braille using printer 100, the printing results vary depending on the type of recording paper, etc. The print control device 200 can cause printer 100 to print a Braille test pattern 410 containing Braille characters 400 under different printing conditions. The user can evaluate Braille test pattern 410 and determine the printing conditions for printing the desired Braille characters 400.

[0142] The input unit 230 receives the Braille character spacing information indicating the difference between the reference parameter and the adjustment parameter. Preferably, the data generating unit 253 generates the adjustment parameter based on the reference dot setting information and the Braille character spacing information.

[0143] The user can adjust the difference in shape of the plurality of Braille patch images 411 within the Braille test chart 410 to a desired difference.

[0144] Preferably, when the input unit 230 receives reference point setting information including a height setting value, the data generation unit 253 generates a reference parameter including the number of ink layers 407 corresponding to the height setting value, i.e., an ink layer number setting value, and generates an adjustment parameter including an adjustment ink layer number setting value different from the ink layer number setting value.

[0145] The print control device 200 can convert the shape of the dot 403 into data that easily corresponds to the printing conditions of the printer 100 .

[0146] The print control program PG causes the print control device 200 to execute the data generation unit 253 for generating test chart print data, which causes the printer 100 to print a braille test chart 410 composed of a plurality of braille patch images 411, including a reference braille patch image 411a and an adjustment braille patch image 411b, and the communication control unit 255 for transmitting the test chart print data to the printer 100. The data generation unit 253 causes the reference parameters associated with the reference points 403a included in the reference braille patch image 411a to differ from the adjustment parameters associated with the adjustment points 403b included in the adjustment braille patch image 411b.

[0147] The print control program PG can cause the printer 100 to print a Braille test chart 410 including Braille characters 400 with different printing conditions. The user can evaluate the Braille test chart 410 and thereby determine the printing conditions for printing the desired Braille characters 400.
