Description

Technical Field

[0001] This invention relates to the field of digital printing technology, and more specifically to a precise color control printing method. Background Technology

[0002] There is no unified color matching standard for digital printing of textiles. The colors in the standard color library in the software will vary slightly from the printed colors due to differences in printing equipment, ink, and fabric. This means that patterns designed by designers using colors from the standard color library in the software will appear differently on the printed fabric, making it impossible to completely reproduce the designed pattern. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a precise color control printing method.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A precise color control printing method includes the following steps:

[0006] Creating a standard color chart library in digital color software;

[0007] Based on the size of the printing equipment and the width of the printing fabric, a layout diagram is generated from the standard color card library;

[0008] The printing equipment prints the layout diagram to form a physical color card;

[0009] The colors of each printed physical color card are collected to generate a printed color card library;

[0010] The colors in the printing color chart library are matched with the colors in the standard color chart library in the digital color software to generate a color matching file containing printing device information, ink information, fabric information, and color number information.

[0011] Authorize the color matching file to the designer;

[0012] Designers use the colors from the standard color chart library in digital color software to create the pattern to be printed based on the matching file, and then send the designed pattern to the corresponding printing device for printing.

[0013] As a preferred option, the standard color library is either the Lab color library or the Pantone color library.

[0014] Preferably, a remote printing platform is set up, which includes a server with a pattern upload module, a printing device driver module, an access control module, and a storage module. The matching file is stored in the remote printing platform; the control of the remote printing platform is authorized to the designer; the designer uses the colors in the standard color card library in digital color software to create the pattern to be printed based on the matching file, uploads the pattern to the remote printing platform, and the remote printing platform controls the corresponding printing device to print.

[0015] As a preferred option, the server is equipped with an information security protection module.

[0016] As a preferred option, the color swatches in the layout diagram are arranged in a matrix.

[0017] Preferably, the color card is a 20mm*20mm square or a 20mm diameter circle.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the printing colors match the standard color card library, the actual colors that the designer wants when designing the pattern can be selected from the corresponding standard color card in the software, and the designed pattern can perfectly reproduce the designer's idea after printing, without affecting the effect due to color difference, thus achieving color accuracy; the designer can also remotely control the printing, without being limited by space and time. Detailed Implementation

[0019] A precise color control printing method includes the following steps:

[0020] In digital color software, a standard color chart library is created. The standard color chart library is either the Lab color library or the Pantone color chart library.

[0021] Based on the size of the printing equipment and the width of the printing fabric, the color cards in the standard color card library are arranged to form a printing layout diagram. The color cards in the printing layout diagram are arranged in a matrix. The shape of the color cards is a 20mm*20mm square or a circle with a diameter of 20mm. In this example, the printing layout diagram has 60 columns, the spacing between two adjacent columns is set to 5mm, each column has 60 color cards, and the spacing between the color cards is set to 2mm.

[0022] The printing equipment prints the layout graphics onto the fabric to form a physical color card. The fabric is made of common materials such as cotton, rayon, and chemical fiber to increase versatility.

[0023] For physical color cards, colors are collected one by one using a color pen or colorimeter and entered into the computer to generate a printable color card library.

[0024] The colors in the printing color chart library are matched and associated with the colors in the standard color chart library in the digital color software to generate a color matching file containing printing device information, ink information, fabric information, and color number information;

[0025] Authorize the color matching file to the designer;

[0026] Designers need to find the corresponding standard color chart in the color library for the colors they want to present on the fabric by matching files. Designers then use the colors in the standard color chart in digital color software to create the pattern to be printed on the fabric. The designed pattern is then sent to the corresponding printing device for printing, resulting in fabric with accurate colors.

[0027] In the above printing method, the designer's computer and the printing device need to be on the same network to directly send the pattern to the corresponding printing device. To achieve remote printing, a remote printing platform needs to be set up to connect the designer's computer and the printing device. The remote printing platform includes a server with a pattern upload module, a printing device driver module, an access control module, a storage module, and an information security protection module. The color matching file is stored in the remote printing platform and named according to its serial number in the storage module. The designer is granted control of the remote printing platform. The designer uploads the designed pattern and the serial number of the color matching file to the remote printing platform. The remote printing platform controls the same printing device with the same ink to print on the corresponding fabric based on the information in the corresponding color matching file.

[0028] Fabric color printing uses either direct-to-garment digital printing or thermal transfer digital printing. When fabric color printing uses direct-to-garment digital printing, the printing steps include sizing, printing, steaming, washing, setting, and finishing. When fabric color printing uses thermal transfer digital printing, the printing steps include printing on thermal transfer paper and transferring it to the fabric.

[0029] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
