Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to an ink output control method, device, equipment and storage medium based on feathering. Background Art

[0002] Inkjet printers can turn colored liquid ink into fine particles through nozzles and spray them onto printing paper, thus forming words or patterns. Existing methods of printing images with inkjet printers include one-pass printing (single pass) and multiple-pass printing (multi-pass). Multiple-pass printing can be understood as printing a picture in several passes, which usually means that the same pixel is printed multiple times by the printer's nozzle. The more passes, the better the effect. The substrate can also absorb ink in batches, and the picture will be more delicate.

[0003] In many actual printing scenarios, it is necessary to increase white ink. For example, the pattern printed on the mobile phone case now needs to be printed on tiles. Due to the enlargement of the image and the presentation of the effect, the white ink needs to be doubled; or: the image printed on the plane needs to be doubled in order to present the three-dimensional and relief effects; or: T-shirts are printed on the bottom, and it is found that the white ink has a poor bottoming effect and there are loopholes. At this time, the white ink doubling function is needed to thicken the bottom white ink to avoid loopholes affecting the printing of color ink. In the prior art, when the white ink increase function is turned on, the white ink is doubled while increasing the feathering, and the feathering will reduce the number of ink points per pass of the color ink and white ink, so the number of ink passes (i.e., the number of prints) will increase, resulting in a decrease in printing output.

[0004] Take the printing mode of 360x2400-4pass with simultaneous ink output of white and color as an example. The printing accuracy of 360x2400 has a total of 2400 ink output points. When feathering is not turned on, 2400 ink output points are printed in 4 passes, and the actual number of ink output points per pass is 600 points. 4 passes print all 2400 points. When 100% feathering is turned on, 2400 ink output points are printed in 8 passes, and the actual number of ink output points per pass is reduced from 600 points to 300 points. In the end, both white ink and color ink will have 2400 points. When the white ink doubling function is turned on, the actual number of passes printed will double, and the printing output will also decrease accordingly. For example, if the thickness of white ink needs to be doubled, the function of double white ink will be turned on, and the 2400 ink points of white ink will become 4800 ink points. When 100% feathering is turned on, the image that was originally printed with 8 passes now needs 16 passes. Although this method realizes the function of doubling white ink, the number of passes for printing is also doubled, resulting in a reduction of half of the printing output. Summary of the invention

[0043] Embodiment 1

[0044] See also Figure 1 , Embodiment 1 of the present invention provides an ink discharge control method based on feathering, wherein: Figure 1 As shown, the method comprises the following steps:

[0045] S101, determining the initial ink output point number according to the printing accuracy;

[0046] Among them, the printing precision is determined according to the printing requirements, and different printing precisions correspond to different ink output points. For example: taking the printing mode of printing 360x2400-4pass with simultaneous white and color ink output as an example, the printing precision of 360x2400 has a total of 2400 ink output points, and the corresponding initial ink output point number is 2400. In the printing mode of simultaneous white and color ink output, the initial ink output point number is the initial total ink output point number of white ink and color ink. That is, in the printing mode of simultaneous white and color ink output, the initial total ink output point number of white ink is 2400, and the initial total ink output point number of color ink is also 2400.

[0047] S102, determining whether to enter the white ink adding mode;

[0048] For example, a user's instruction to start the white ink increase mode can be received through a preset button, and when the user presses the preset button, it is determined to enter the white ink increase mode. The situations in which the white ink increase mode is entered may include: a pattern printed on a mobile phone case now needs to be printed on a tile, and the white ink needs to be doubled due to the image enlargement and effect presentation; or: a flat printed image needs to have a three-dimensional and relief effect, and the white ink needs to be doubled; or: a T-shirt is printed on the bottom, and it is found that the white ink bottoming effect is poor and there are holes, and the white ink doubling function is needed to thicken the bottom white ink to avoid the holes affecting the printing of color ink.

[0049] S103, if entering the white ink increase mode, determining the corresponding feathering amplitude and the actual number of white ink points per pass according to the white ink increase multiple and the initial number of ink points;

[0050] Exemplarily, when entering the white ink increase mode, the white ink increase multiple input by the user can be received, and the actual number of white ink points can be determined based on the white ink increase multiple and the initial number of white ink points; the feathering amplitude and the actual number of white ink points per pass can be determined based on the actual number of white ink points.

[0051] Wherein: the white ink increase multiple can be determined according to the printing requirements, and can be a positive multiple or a decimal multiple. The actual number of white ink dots N1 = white ink increase multiple L × initial number of ink dots N0.

[0052] In this embodiment, the feathering amplitude and the actual number of ink points per pass of white ink can be determined according to the actual number of ink points of white ink in a variety of ways. In one example, the actual number of ink points per pass of white ink can be fixed first, such as setting the actual number of ink points per pass of white ink to a fixed value N, wherein N is greater than the actual number of ink points per pass of color ink, thereby ensuring that in actual printing, the number of ink points per pass of white ink is greater than the number of ink points per pass of color ink, thereby achieving the effect of increasing the thickness of white ink without increasing the number of passes. Preferably, N is the maximum number of ink points per pass. Then determining the feathering amplitude according to the actual number of ink points of white ink and the fixed value N includes:

[0053] S11, determining the actual number of printing passes according to the actual number of white ink dots and the fixed value N;

[0054] The actual number of printing passes = the actual number of white ink dots N1 / the fixed value N.

[0055] S12, determining the initial printing pass number according to the initial ink output point number and the maximum ink output point number of each pass;

[0056] The initial printing pass number refers to the number of passes required to print the initial ink dots without adding feathering. Then the initial printing pass number = initial ink dots / maximum ink dots per pass.

[0057] S13, determining the feathering amplitude according to the actual printing pass number and the initial printing pass number.

[0058] Wherein: Feathering amplitude = (actual printing pass number - initial printing pass number) / initial printing pass number.

[0059] In another example, the feathering amplitude may be fixed to a fixed value, and then determining the actual number of ink points of the white ink per pass according to the actual number of ink points of the white ink and the fixed feathering amplitude includes:

[0060] S21, determining the initial printing pass number according to the initial ink output point number and the maximum ink output point number of each pass;

[0061] The initial printing pass number refers to the number of passes required to print the initial ink dots without adding feathering. Then the initial printing pass number = initial ink dots / maximum ink dots per pass.

[0062] S22, receiving a fixed feathering amplitude and determining an actual number of printing passes according to the fixed feathering amplitude;

[0063] Exemplarily, a fixed value input by a user is received and used as a fixed feathering amplitude; wherein: actual number of printing passes = initial number of printing passes × fixed feathering amplitude + initial number of printing passes.

[0064] S22. Determine the actual number of dots of white ink per pass according to the actual number of dots of white ink and the actual number of printing passes.

[0065] Wherein: the actual number of dots of white ink per pass = the actual number of dots of white ink / the actual number of printing passes.

[0066] In another example, the white ink increase multiple and the initial ink point number can be used as the first parameter pair, and the feathering amplitude and the actual ink point number of each white ink pass can be used as the second parameter pair; before this step, the corresponding relationship between the first parameter pair and the second parameter pair is pre-configured; for example, the first parameter pair is: the white ink increase multiple is 2, the initial ink point number is 2400, and the corresponding second parameter pair is: the feathering amplitude is 100%, and the actual ink point number of each white ink pass is 600. When entering the white ink increase mode, the corresponding feathering amplitude and the actual ink point number of each white ink pass are determined according to the white ink increase multiple and the initial ink point number through the corresponding relationship.

[0067] S104, controlling the ink discharge of the white ink nozzle according to the feathering amplitude and the actual number of ink discharge points per pass of the white ink.

[0068] Specifically, the feathering of the feathering amplitude is turned on, and the white ink nozzle is controlled to print the actual number of dots of the white ink per pass. For example, if the feathering amplitude is 50%, and the actual number of dots of the white ink per pass is 400, then 50% feathering is turned on, and the white ink nozzle is controlled to print 400 dots per pass.

[0069] In addition, in the printing mode of simultaneous white and color ink discharge, color ink can be printed while printing white ink. Therefore, in this step, the actual ink discharge point number of color ink per pass can be determined according to the initial ink discharge point number and the feathering amplitude; the color ink nozzle is controlled to discharge ink according to the feathering amplitude and the actual ink discharge point number of color ink per pass. Among them: the feathering amplitude is the feathering amplitude determined in S103, and the actual ink discharge point number of color ink per pass = the initial ink discharge point number / the maximum ink discharge point number per pass × (1 + feathering amplitude).

[0070] Furthermore, if the result of the judgment in step S102 is: the white ink increase mode has not been entered, indicating that the current printing is performed in the normal printing mode, then the number of ink points per pass of the white ink is the same as the number of ink points per pass of the color ink. In the case of no feathering, the number of ink points per pass of the white ink and the number of ink points per pass of the color ink are both the maximum number of ink points per pass; in the case of feathering, the feathering amplitude input by the user is received, and the number of ink points per pass of the white ink and the number of ink points per pass of the color ink are determined according to the initial number of ink points and the feathering amplitude input by the user; then, the white ink nozzle is controlled to discharge ink according to the feathering amplitude and the number of ink points per pass of the white ink; and the color ink nozzle is controlled to discharge ink according to the feathering amplitude and the number of ink points per pass of the color ink. Wherein: the number of ink points per pass of the white ink / color ink = the maximum number of ink points per pass ÷ (1 + feathering amplitude); the feathering amplitude here is the feathering amplitude input by the user.

[0071] Embodiment 2

[0072] In the second embodiment of the present invention, the feathering-based ink discharge control method of the present invention is described by taking the printing mode of printing 360x2400-4pass white and color ink discharge simultaneously as an example. Figure 2 As shown, the method includes:

[0073] S1. Determine the initial ink output point number according to the printing accuracy;

[0074] The printing precision of 360x2400 has a total of 2400 ink points, so the corresponding initial ink point number is 2400. In the printing mode of white and color ink simultaneous output, if the white ink does not need to be increased, the number of white ink points and the number of color ink points are the same, both of which are the initial ink points.

[0075] S2, determining whether to enter the white ink adding mode;

[0076] The specific determination is based on the user input command. For example, if the user presses the white ink increase function button, the white ink increase mode is entered, otherwise, the white ink increase mode is not entered.

[0077] S3. If the white ink increase mode is entered, the corresponding feathering amplitude and the actual number of white ink points per pass are determined according to the white ink increase multiple and the initial number of ink points; the actual number of color ink points per pass is determined according to the initial number of ink points and the feathering amplitude;

[0078] For example, if the user inputs a white ink increase factor of 2, the actual number of white ink dots is 4800. When determining the corresponding feathering amplitude and the actual number of white ink dots per pass, the following three methods can be used:

[0079] Method 1: Fix the actual number of ink points per pass; determine the feathering amplitude based on the actual number of white ink points and the fixed actual number of ink points per pass: If the system fixes the actual number of white ink points per pass to 600, the actual number of printing passes is 8, the initial number of printing passes is 4, and the feathering amplitude is 100%.

[0080] Method 2: Fixed feathering amplitude, determine the actual number of dots of white ink per pass according to the actual number of dots of white ink and the fixed feathering amplitude: Wherein: the fixed feathering amplitude can be obtained through user input, for example, the user inputs the feathering amplitude as 50%, the actual number of printing passes is 6, the initial number of printing passes is 4, and the actual number of dots of white ink per pass is 800. At this time, the actual number of dots of white ink per pass 800 is greater than the maximum number of dots of white ink per pass 600, and the user can be prompted to correct the feathering amplitude, and the user re-enters the feathering amplitude, and the actual number of dots of white ink per pass is re-determined according to the new feathering amplitude.

[0081] Method 3: Use the white ink increase multiple and the initial ink point number as the first parameter pair, and use the feathering amplitude and the actual ink point number of each pass of the white ink as the second parameter pair; pre-configure the corresponding relationship between the first parameter pair and the second parameter pair; obtain the corresponding feathering amplitude and the actual ink point number of each pass of the white ink by searching the corresponding relationship. For example, in this embodiment, the white ink increase multiple input by the user is 2 times, and the initial ink point number is 2400. By searching the corresponding relationship, the corresponding second parameter pair is obtained as follows: the feathering amplitude is 100%, and the actual ink point number of each pass of the white ink is 600.

[0082] After the feathering amplitude is 100% obtained by any of the above methods, the actual number of ink points per color ink pass is determined according to the initial number of ink points and the feathering amplitude; the actual number of ink points per color ink pass is 300 points.

[0083] S4, controlling the ink discharge of the white ink nozzle according to the feathering amplitude and the actual number of ink discharge points per pass of the white ink; determining the actual number of ink discharge points per pass of the color ink according to the initial number of ink discharge points and the feathering amplitude;

[0084] In this embodiment: 100% feathering is turned on, the white ink nozzle is controlled to print 600 dots per pass, and the color ink nozzle is controlled to print 300 dots per pass, which can be completed through 8 passes. While doubling the white ink, the number of printing passes will not be increased, thereby improving the printing output.

[0085] S5. If the white ink increase mode is not entered, the white ink nozzle is controlled to discharge ink according to the number of ink discharge points per pass of the white ink, and the color ink nozzle is controlled to discharge ink according to the number of ink discharge points per pass of the color ink.

[0086] If the result of the judgment in step S2 does not enter the white ink increase mode, the normal white and color printing mode is followed, and the number of ink dots per pass of the white ink is the same as the number of ink dots per pass of the color ink. In the case of no feathering, the number of ink dots per pass of the white ink and the number of ink dots per pass of the color ink are both 600, and the printing is completed through 4 passes. In the case of feathering, the feathering amplitude input by the user is received, for example, if the feathering amplitude is 50%, the number of ink dots per pass of the white ink / color ink is 400, and the feathering is turned on by 50%, and the white ink nozzle is controlled to print 400 dots per pass, and the color ink nozzle is controlled to print 400 dots per pass, and the printing is completed through 6 passes.
