[0002] Digital printing is widely recognized by the market and customers for its features such as no need for plate making, no restrictions on the number of color sets, high precision, rich layers and green environmental protection, and has been vigorously developed at home and abroad. At present, the upstream and downstream of digital printing still mainly rely on on-site sample viewing to determine the color, or mail samples to customers for sample viewing to determine the color. This method of viewing samples is not only high in distance cost, but also time-consuming, which is not conducive to digital printing's response to the fast fashion market.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] In order to facilitate the understanding of this embodiment, the technical terms designed in this application are briefly introduced below.

[0025] Digital printing refers to a printing method that uses digital technology to print design patterns directly onto fabrics or other materials. Compared with traditional printing processes, digital printing has higher flexibility and efficiency, can meet the production needs of small batches and multiple varieties, and can also provide richer color expression and higher pattern accuracy. In addition, due to the reduction of the plate-making process in traditional printing, digital printing also performs well in environmental protection, which can effectively reduce water and energy consumption and reduce wastewater discharge.

[0026] After introducing the technical terms involved in this application, the application scenarios and design concepts of the embodiments of this application are briefly introduced.

[0027] At present, the upstream and downstream cooperation in the digital printing industry mainly relies on on-site inspection or mailing samples to confirm the color. This method has the disadvantages of high cost and long time. In addition, since the colors of the monitors used by different terminals cannot be unified, the production end cannot accurately reproduce the designer's design intentions or respond to user needs, which not only affects the rapid development of the digital printing industry but also makes it difficult to meet the personalized needs of customers.

[0028] Based on this, an embodiment of the present application provides a remote sample viewing method for digital printing.

[0029] Example 1 The present application provides a digital printing remote sample viewing method, which is applied to a client, the client is communicatively connected with multiple digital printing factory terminals, and the client and the multiple digital printing factory terminals are integrated into a sample viewing device with the same configuration.

[0030] Combination Figure 1 As shown, the digital printing remote sample viewing method includes: S110, in response to the user's operation of confirming the name of the digital printing factory, determining a target digital printing factory end.

[0031] S120, sending a sample viewing request to a target digital printing factory; wherein the sample viewing request carries a target pattern.

[0032] S130, receiving a sample standard corresponding to the target pattern returned by the target digital printing factory.

[0033] S140, open the sample standard and load the icc color database on the specified fabric to simulate the color with soft proofing.

[0034] S150, in response to the adjustment operation of the color attribute parameters of the sample standard plate, updating the icc color database.

[0035] S160, sending the updated icc color database to the target digital printing factory.

[0036] In this embodiment, "client" refers to a computer or terminal device used by a user or operator; "multiple digital printing factory terminals" refers to multiple digital printing production facilities or machines located in different locations, which can receive instructions or data from the client. Since "the client is in communication connection with multiple digital printing factory terminals", it means that the client can exchange information with these digital printing factory terminals through the network or other communication means, such as sending design files, production instructions, etc.

[0037] In addition, "the client and multiple digital printing factories are integrated into a sample viewing device with the same configuration". The "sample viewing device" is usually used to preview the appearance of the final product before formal production to ensure that the color, pattern, etc. meet the expected standards. In this way, the factors that cause the color to be inconsistent due to different displays used by different terminals can be effectively reduced, which is conducive to improving production efficiency and product quality consistency.

[0038] In step S110, when the user confirms the name of a digital printing factory, the system will find the target digital printing factory end among the multiple digital printing factory ends for communication connection according to the name. In short, the "name of the digital printing factory" is used as a unique identifier or search basis, and based on the "name of the digital printing factory", it can be quickly determined which digital printing factory end the user wants to communicate with.

[0039] It can be understood that a one-to-one correspondence between multiple "digital printing factory ends" and multiple "digital printing factory names" is pre-stored in the client or in the cloud connected to the client, and the target digital printing factory end can be quickly determined through the one-to-one correspondence.

[0040] Afterwards, step S120 sends a sample viewing request to the determined target digital printing factory to access various information supported by the target digital printing factory for processing and production, such as fabric types, processing technology, color data, etc.

[0041] Then, wait for the sample standard sent by the target digital printing factory, and open the sample standard in step S140 and load the color database of the fabric to be digitally printed for soft proofing simulation to visually observe the simulation effect of digital printing. In this process, since the configuration of the sample viewing device corresponding to the user end and the target digital printing factory end is the same, the color difference problem caused by different displays can be effectively avoided; wherein, the simulation soft proofing software used in step S140 must meet the following conditions: it can load both RGB and CMYK color profiles icc and multi-channel color profiles icc. In the embodiment of the present application, the software can be selected from ATSoftProof independently developed by Honghua.

[0042] Afterwards, step S150 adjusts the color attribute parameters according to the personalized needs of the customer, and stores the parameter records in the adjustment process in the configuration file of the icc color database to update the icc color database.

[0043] Afterwards, step S160 returns the updated icc color database to the target digital printing factory, so that the target digital printing factory can make adaptive process adjustments based on the customer's personalized needs, thereby improving customer experience and satisfaction.

[0044] In combination with the first aspect, the sample viewing device includes: a sample viewing inclined platform 1, a display component 2, a D65 light source 3 and an ambient light interference prevention component 4.

[0045] Combination Figure 2 As shown, the anti-ambient light interference component 4 is arranged on the sample viewing inclined platform 1, and the anti-ambient light interference component 4 and the sample viewing inclined platform 1 are surrounded to form a sample viewing space with an open portion.

[0046] It is understandable that the anti-ambient light interference component 4 should have a certain strength and can prevent the influence of ambient light on the viewing. In this embodiment, the anti-ambient light interference component 4 is made of N75 gray non-woven fabric panel with good light absorption effect and less diffuse reflection, which is used to block the light directed into the viewing space.

[0047] The display component 2 is arranged inside the viewing space and opposite to the open portion, and the color gamut of the display component 2 covers at least 99% of the AdobeRGB color space.

[0048] It is understandable that the display component 2 here may refer to a device such as a display or screen that can display images or colors. The color range (color gamut) of the display component 2 can cover at least 99% of the Adobe RGB color space, which means that the display component 2 can present a very wide range of colors, almost covering all colors defined by the Adobe RGB standard. Among them, AdobeRGB is a color space widely used in printing and professional image processing. Its color gamut is wider than the common sRGB, so it can provide richer and more accurate color performance. In addition, the display component 2 should have good stability and a long service life. In this embodiment, the screen color difference of the display component 2 within a natural month should be less than or equal to 1, and the service life should be no less than 5000 hours.

[0049] The top surface of the sample viewing ramp 1 gradually decreases in height from the direction close to the display assembly 2 to the direction away from the display assembly 2. That is, one end of the sample viewing ramp 1 is higher, while the other end is lower, forming a slope, and such a design can be used to better adapt to or cooperate with the installation and use of the display assembly 2.

[0050] The D65 light source 3 is disposed above the display component 2 , and a specified distance exists between a side of the D65 light source close to the display component 2 and a plane where the display component 2 is located.

[0051] Among them, the D65 light source 3 is a standard light source, which is often used for color management and calibration. In this embodiment, the D65 light source should meet the light source requirements of ISO3664. In addition, the D65 light source 3 is placed above the display component 2 and maintains a certain distance from the plane where the display component 2 is located. This setting is usually to ensure that when evaluating or calibrating the color of the display component 2, the light on each plane in the viewing space has good uniformity, and the influence of the light source can be standardized, thereby ensuring the consistency and accuracy of the test results.

[0052] In combination with the first aspect, the tilt angle of the sample viewing ramp 1 is 45°. According to the principle of ergonomics, a sample viewing ramp with a tilt angle of 45° is provided and a standard white sample viewing background is used for easy viewing.

[0053] In combination with the first aspect, step S150 includes: S151, measuring first chromaticity values ​​of multiple colors of the color block combination unit of the sample standard plate on the display component, and second chromaticity values ​​of multiple colors of the color block combination unit of the sample test standard plate.

[0054] S152, for each color, calculating color difference evaluation data between the first chromaticity value and the second chromaticity value, the color difference evaluation data at least including lightness difference, chroma difference, and hue difference; S153, combining the color difference evaluation data, adjusting the color attribute parameters according to a preset adjustment sequence, and writing the adjustment information into a configuration file of an icc color database to obtain an updated icc color database.

[0055] It is understandable that in step S140, after the soft proofing software (such as the "ATSoftProof" software commonly used in color management and pre-printing preparation in the prior art, which usually has advanced color management functions, supports multiple ICC profiles, and provides flexible display setting options to adapt to different workflow requirements) is opened on the client to simulate the final printing effect on the display component 2, if the user is not satisfied with the effect of the soft printing or wants to make further adjustments, the parameters of the color management module in each direction can be adjusted on the software (wherein the adjustment may include dragging, clicking, inputting parameters, etc.). For users who use it for the first time or have little experience, there may be situations where the adjustment direction is wrong or the parameters cannot be adjusted accurately to meet the personalized customization needs. For example, a certain parameter (such as saturation) should be increased, but the user currently only knows that the parameter needs to be adjusted but does not know whether to increase or decrease the parameter. If the user decreases the parameter several times and finds that the adjustment direction is wrong and then increases the parameter again, this will undoubtedly increase the time for the user to adjust the parameter. In the present application, color difference evaluation can be used to help users quickly understand how to adjust the parameters, thereby shortening the time required for users to adjust the parameters.

[0056] Specifically, in Figure 2 The proofing device shown starts the soft proofing software, sets the soft proofing simulation parameters, opens the proofing standard sent by the target digital printing factory in step S130, and loads the icc color database of the fabric of the target digital printing factory in step S140, soft proofs to simulate the sample color, and obtains the sample test standard.

[0057] Afterwards, the chromaticity value of each color in the color block combination unit in the sample standard sent by the target digital printing factory in step S130 is measured by a spectrophotometer to obtain a plurality of first chromaticity values ​​corresponding to the plurality of colors. , and save it to the specified txt format document.

[0058] Similarly, the spectrophotometer is used to measure the chromaticity value of each color in the same color block combination unit of the sample test standard obtained by soft proofing in step S140 to obtain multiple second chromaticity values, and save them to the specified document. , and saved in a specified txt format document. It is worth noting that these two txt format documents can be the same document.

[0059] Then, in step S152, the brightness difference between the screen color and the sample color is obtained by using the CIE1976 chroma difference and hue difference calculation method. , color difference and color difference Specifically, it is calculated using the following formula:

[0060]

[0061]

[0062]

[0063]

[0064] in, is the chroma, For color difference, It is CIE1976 color difference.

[0065] Then, the brightness difference is combined with the color difference evaluation data , color difference and color difference Through these color difference evaluation data, users can quickly understand how to adjust the color to meet their personal color needs. Then, according to the user's color perception and personalized color needs, the color display effect is adjusted in sequence from hue, saturation, brightness, contrast, and R, G, B, and C, M, Y color channels, and the adjustment information in the adjustment process is written into the configuration file of the icc color database, thereby updating the icc color database and obtaining an icc color database that meets the user's personalized needs.

[0066] For example, based on steps S151-S152, the user perceives the color to be reddish and darker. As an example, the brightness can be adjusted by +5 and the red (R) color channel by -8 (the specific values ​​depend on the situation and are only examples here and are subject to limitation).

[0067] Example 2 This embodiment provides a remote sample viewing method for digital printing, which is applied to a digital printing factory end; the digital printing factory end is connected to multiple clients for communication, and the digital printing factory end and the clients are integrated into a sample viewing device with the same configuration. It can be understood that each digital printing factory end can be connected to multiple clients for communication to receive production order information from different clients, exchange information with each client to accept personalized color production instructions from each client, etc. The digital printing factory end and the client end are integrated into a sample viewing device with the same configuration such as Figure 2 The viewing device shown can effectively avoid color differences caused by different display components 2, which is conducive to achieving color consistency.

[0068] Combination Figure 3 As shown, the method includes: S210, receiving a sample viewing request sent by a client, wherein the sample viewing request carries target fabric information and target pattern.

[0069] S220, generating a test standard for remote soft proofing evaluation based on the sample viewing request, and retrieving an icc color database corresponding to the target fabric.

[0070] S230, sending the test standard plate and the icc color database to the client.

[0071] S240: Receive an updated icc color database sent by the client.

[0072] S250, performing digital printing according to the updated icc color database to obtain a target digital printing result.

[0073] When the digital printing factory receives the sample viewing request sent by the client, it calls the local database based on the target fabric information carried in the sample viewing request to select the digital printing machine icc color database corresponding to the target fabric, and generates a test standard based on the target image. Then, the test standard corresponding to the sample viewing request and the digital printing machine icc color database are sent to the client for the client to confirm the color data.

[0074] After the client confirms the color data or adjusts the icc color database, the final icc database will be returned to the digital printing factory, which will then accept the updated icc database and perform digital printing based on the icc database to meet the client's personalized color needs.

[0075] In combination with the second aspect, before step S210, the method further includes: S200, obtaining digital printing characteristic parameters of the historical product line corresponding to the digital printing factory.

[0076] S201, combining all digital printing characteristic parameters to construct an icc color database.

[0077] S202, establishing and storing a correspondence between an icc color database and the name of a digital printing factory, and obtaining an icc color database of a digital printing machine of the digital printing factory.

[0078] The digital printing characteristic parameters include at least: textile type, medium thickness, ink type, sizing type and printing parameters.

[0079] It is understandable that before actual application, each digital printing factory should first establish its own digital printing machine icc color database. Specifically, according to the factory's existing product line, the name of the digital printing factory is used as the only retrieval basis, and the digital printing machine icc color database is characterized by textile type, media thickness, ink type, sizing type and printing parameters (if the factory only provides thermal transfer process, there is no sizing type characteristic parameter) for computer monitors to simulate printer colors.

[0080] In conjunction with the second aspect, step S201 includes: S2011, create an initial color table.

[0081] S2012, for each fabric, an icc color database corresponding to the fabric is established according to the sizing type characteristic data and the printing characteristic data.

[0082] In conjunction with the second aspect, step S2012 includes: S20120, for each sizing type characteristic data and printing characteristic data, the fabric to be printed is sizing treated and marked with a sizing type label.

[0083] S20121, using a digital printing machine to print the initial color table on the sizing-treated fabric, and then steaming, washing, drying, shaping and stenting to obtain a flat color sample.

[0084] S20122, measuring the chromaticity value of the color sample to obtain spectral data.

[0085] S20123, convert the spectral data into LAB data, and generate the color profile icc of the fabric sample through the specified software.

[0086] S20124, naming the color configuration file icc according to a preset naming format, and obtaining the color configuration file icc corresponding to the sizing type characteristic data and the printing characteristic data on the fabric.

[0087] S20125, combine all color profiles icc to obtain the icc color database corresponding to the fabric.

[0088] The initial color table can be set and produced by yourself or obtained from a third party, which is not limited here. Afterwards, for different fabrics, according to the various characteristic data of the fabric, an icc color database of the digital printing machine for each fabric is established. Specifically, the establishment process of the icc color database of the digital printing of active cotton fabric in Factory A is taken as an example to explain: First, create an initial color table.

[0089] The cotton fabrics were then classified and given names, such as 40 poplin, according to their weaving structure, thickness, and color expression.

[0090] Afterwards, the fabric to be printed is sizing treated according to the order requirements and the corresponding sizing type of the digital printing factory, and the sizing type is marked.

[0091] Then, based on the setting of printing parameters, the initial color table is printed on the sizing fabric using a digital printing machine, and then after steaming, washing, drying, shaping and stretching, a flat color sample is obtained.

[0092] Then, the color sample is measured using a spectrophotometer to obtain spectral data, which is then converted into LAB data.

[0093] Subsequently, the data obtained in the above process is used to generate the color profile icc of the fabric sample through the software i1profiler, and the color profile icc is named with factory name + textile type + media thickness + ink type + sizing type + printing parameters + date.

[0094] Subsequently, according to the different fabrics, different sizing types, and different printing parameters, the steps of processing the fabric to generate the corresponding color profile icc are repeated to establish the icc color database of digital printing of active cotton fabrics in Factory A.

[0095] Similarly, the color database of Factory A is established with reference to other factories, so that the color database of each digital printing factory can be established. It can be understood that the color database constructed by the above method can also be connected to the terminal of the front-end designer for early preview, color design, etc.

[0096] Example 3 In a third aspect, the embodiment of the present application provides a personalized digital printing remote sample viewing device, which is applied to a client, and the client is connected to multiple digital printing factory terminals for communication. The client and multiple digital printing factory terminals are integrated into a sample viewing device with the same configuration. Figure 4 As shown, the device includes: a determination module 10, a request sending module 20, a sample standard receiving module 30, a soft proofing simulation module 40, an updating module 50 and a returning module 60.

[0097] The determination module 10 is used to determine a target digital printing factory end in response to the operation of confirming the name of the digital printing factory by the user.

[0098] The request sending module 20 is used to send a sample viewing request to a target digital printing factory; wherein the sample viewing request carries a target pattern.

[0099] The sample mark receiving module 30 is used to receive the sample mark corresponding to the target pattern returned by the target digital printing factory.
