How to improve the printing problem of digital printing machine?
The phenomenon is: the image is blurred; there are incomplete graphics in the image: the fineness of the nozzle is not properly adjusted. This is mainly due to the fact that the selected ink jet resolution does not match the grey cloth.
Solution: Due to the weaving method of the gray fabric, the fabric surface cannot be as smooth as paper. Most digital printing machines generally use 360~720dpi inkjet lines. Fine fabrics, such as silk fabrics, rarely squirt to 1440dpi. If the image clarity is infinitely improved, there is no effect. Affects the increase in injection speed. In order to increase the difficulty of hardware and software, the resolution should be reasonably selected according to the fineness of the pattern and the smoothness of the cloth. The height of the nozzle should be adjusted according to the thickness of the fabric: the nozzle is too low, it is easy to block the printhead, affecting the color of the pattern: the printhead is too high. The ink moves with the printhead. A certain height from the fabric. It produces a parabolic angle. The boundaries of the printed pattern are blurred. Poor accuracy. The color is not bright enough. So when printing. Adjust the printhead to the proper height.
The color scale of the digital printing machine is not rich enough. Phenomenon: There are two knots in the pattern, the transition of the layer is not natural; the tone expression is not strong; because the dye is not properly selected or not suitable for gray fabric, the level is smoother.
Solution: The digital printing machine sprays a few stars of water to change the color. Inkjet printing as a point drawing. It is okay to display dark colors with high density. Sometimes a little hierarchical. Or because of the redundancy of the color mixing points, it is easy to produce gray and dark colors, which reduces the color brightness and solves the problem of light areas. The use of two color materials, dark and light materials and two-color materials, can increase density. Another method is to pre-mix colors. Also known as "special color" inkjet printing. However, a color matching system and an automatic pulping system must be provided. And the color will be limited
In the printing process, the digital printing machine has coarse surface particles or ink flow. Formed due to improper adjustment or damage of the ink jet port.
Solution: The choice of printing accuracy. Worsted fabrics are generally printed with high precision from 720 dpi to 720 dpi. Print accuracy is directly related to the resolution of the printer. 720dpi resolution for fabric printing. High printing accuracy, can reach the accuracy of 360dpi~360dpi. This not only improves the printing speed, but also satisfies the printing accuracy.

Thicker surface particle size or ink flow
Solution: The choice of printing accuracy. Worsted fabrics are generally printed with high precision from 720 dpi to 720 dpi. Print accuracy is directly related to the resolution of the printer. 720dpi resolution for fabric printing. High printing accuracy, can reach the accuracy of 360dpi~360dpi. This not only improves the printing speed, but also satisfies the printing accuracy.
