How to control the color accuracy of textile digital printing?
Digital printing technology is a convenient and cost-effective printing service, which saves the process and cost of traditional printing plate making. The key practical technologies of digital printing are color, pattern and color fastness. The expression of the pattern can be achieved by color separation and design software, and the color can be achieved by using several different coloring methods.
screen display
Adjust the color of an image by adjusting the colors displayed on the screen, usually by selecting or adjusting colors through an on-screen color menu. This method is very useful when color matching or initial color matching, and it is a commonly used color matching method for designers. However, due to the color development principle of the display screen and the color development principle of the dye on the fabric (the screen is produced by mixing three RGB electron beams, and the dye expresses the color by absorbing certain colors of light), the colors on the screen cannot be all Shown on fabrics, the slight color differences exhibited by dyes also cannot be clearly displayed on the screen. Therefore, this is a rough color grading method and cannot be used for accurate color matching.
Color card method
It is a simple, intuitive and effective method to color the pattern through the color card. International general color cards include RGB color cards, CMYK color cards, Lab color cards, and PANTONE color cards. Pantone is the most common way. Compare the sample with the Pantone color, find the same or similar color code in Pantone, record the corresponding value or number, and enter the color value in the drawing software to adjust the color of the image.
The color tone method is to measure the color of the target color block by a colorimeter, and transmit the measurement result to the PC to print the color. This method uses instruments to determine color, eliminating many artifacts and environmental factors.
The speed and accuracy of the empirical color matching method in the operation process completely depend on the needs of the operator's continuous analysis and accumulation in his daily work. In the process of accumulating experience, it is necessary to continuously accumulate data, and paste the adjusted color with a mark for use when needed. The digital printing experience color method is similar to the traditional printing experience color method, but it is easier to master than the traditional printing experience color method.
