Tips | How to improve the printing precision of digital printing?

01Reduce the size of ink dots and increase the number of ink dots per unit area

The core parameters of the print head are the smallest picoliter of ink dots, and the resolution is directly related to the printing fineness. The difference in the number of picoliters and resolution of the two different nozzles directly leads to the difference in printing fineness. So you can consider reducing the size of ink dots and increasing the number of ink dots per unit area to improve the fineness of digital printing.


02Add light-colored ink of the same color

Since the ink dots present a single color, the number of ink dots must be reduced to leave blank areas in order to express lower-density colors, which of course will result in a decline in image quality. Therefore, if you want to improve the printing precision, you can add light-colored inks of the same color. In the case of low-density output, light ink with more dots can be used instead of thick ink, so as to avoid the original low-density and few dots causing resolution Loss of rate and delicacy. Customers who pursue high-precision printing can use LightCyan and LightMagenta inks, and even black can be equipped with third-order inks (Black, Gray, LightGray).

03collocation combination spot color scheme

In order to express full color, different sizes and numbers of ink dots must be mixed. For example, magenta and yellow can form red and orange. However, the chroma presented by the subtractive color mixing of the three primary colors is not as bright as the direct use of the color ink, so inkjet applications have begun to add complementary color inks. At present, the common complementary color ink configurations are red, green, and blue (Red/Green/Blue) Or orange, green, purple (Orange/Green/Violet), which is what we often call spot color inks.
