Digital printing refers to the printing of expected patterns and colors on textiles through digital technology. Digital printing is used for printing proofing and small batch production, both convenient and cost saving, which mainly saves the process and cost of plate making and network making. The key practical techniques for proofing and production of digital printing are color, graphics and color fastness. The expression of pattern can be achieved through color separation and design software. Color can be achieved through screen display, color card toning, color measurement, experience toning and other methods.
1. Screen display. To adjust the color of an image by adjusting the color displayed on the screen, usually by selecting or adjusting the color on the screen through the color menu. This method is very useful when matching colors or starting to mix colors. It is a common method used by designers. However, because the hair color principle of fluorescent screen is different from the hair color principle of dyes on fabrics, the colors displayed on the screen cannot be fully expressed by dyes on fabrics, and the subtle differences between the colors displayed by dyes cannot be clearly displayed on the screen. Therefore, this is a general method of color mixing, and cannot be used as an exact color mixing.
2. Color card toning method. Adjust colors by comparing the colors in the color card.
3. Color measurement. With the help of color measuring instrument, the target color block is measured, and the color measurement results are input into the computer, and then the color is printed. This method USES instruments to determine color and thus excludes many human and environmental factors.
4. Empirical toning method. The speed of its toning process, the accuracy of the results completely depends on this need operators in the daily work of continuous analysis, accumulation.
Digital printing technology and traditional printing technology are two completely different printing mechanism, digital printing machine proofing has become the mainstream production mode in the western printing industry. At present, more than 90% of the printing enterprises in Europe have adopted digital printing machine for proofing. These enterprises generally believe that digital printing machine has rapid response, low cost and good consistency of proofing effect. Digital printing machine has become an indispensable tool for the printing industry in Europe.
