First, the color method is not scientific:
Traditional printing adopts color-block color-adjusting to color, and digital printing adopts the principle of four-color separation, so color adjustment can only be performed on a computer. At present, most of the digital colorists use Photoshop software for color grading, and Photoshop software color correction is mainly for the printing industry ink and paper, and its parameters are not scientific enough for textiles. In addition, colorists rely entirely on their personal experience for color grading and do not match the advanced equipment of digital printing.
Second, poor color reproducibility:
There are two main reasons for bad replay:
On the one hand, it is determined by the principle of four-color separation. The color separation principle of the four-color separation is to form a secondary or tertiary color after spatially mixing the reflected light of cyan, magenta, and yellow. Therefore, as long as any one of the three colors of cyan, magenta, and yellow is changed, the mixed colors will change greatly.
On the other hand, it is influenced by reactive dyes. Now most of the reactive dye inks used in digital printing are high-temperature K-type dyes. These dyes are highly sensitive to humidity, humidity in the air, humidity in the steam box, The moisture content of the fabric, if one of the factors is inconsistent, will significantly affect the shade of digital printing.
Third, the color is not bright enough:
If the color of the digital printing is dominated by three-colored ash, coffee, dark green, etc., that is, a color, three or four inks of cyan, magenta, yellow, and black are required to be mixed together. Then, the vividness of the color will deteriorate. This is because the three colors of cyan, magenta, and yellow are mixed to produce a certain grayscale.
Most of the colors of the printing are three colors, and three or four inks of cyan, magenta, yellow, and black are required to be mixed together, which will produce a certain gray scale. After the printing, the brightness of the products is not good enough.
In addition to the poor color vividness caused by color blending, the use of reactive dyes for digital printing can also cause the color to become less vivid.
The reasons are as follows:
Slurry water absorption and osmosis;
Absorption of fabrics and dyes;
Three primary color shades are not standard;
Reactive dye black ink problem .
Fourth, the ink droplet size can not be adjusted according to the pattern:
Many digital printers available on the market today can realize droplet size adjustment. However, this adjustment is entirely an overall droplet adjustment, that is, when the ink droplets 5PL are printed, all the nozzles can be supplied by 5PL; when the ink droplets 50PL are printed, all the nozzle droplet sizes are all 50PL.
Digital printing can not automatically change the size of the ink jet according to the different conditions of the pattern, and automatically changes the size of the ink jet according to different parts of the block surface and the line. In this way, it is impossible to satisfy the differences in different parts of the pattern, which will greatly reduce the beauty of the pattern.
Fifth, the sizing system is not perfect:
Mainly in the two major aspects of sizing equipment and additives must fully meet the needs of digital printing. However, there is no good special equipment for the uniformity of the sizing, skew control, speed, sizing on demand, etc.; auxiliaries are also lacking in personalization.
It is hoped that in the future development of digital printing, continuous improvements can be made, such as the development of nozzles and control software that can automatically adjust the size of ink droplets in accordance with the requirements of different parts of the flower pattern, and develop better quality sizing equipment and additives. Improve the sizing system; study the scientific color grading method, reduce the dependence on the colorist's experience, and develop a set of perfect process technology and special auxiliaries to improve the color reproducibility and vividness of digital printing.
