[UV Ink] UV Printing Ink Process Reasonable Distribution

Different properties of the printed matter should be selected for different inks. Consider the light transmission, curing rate, the coverability of the ink, and the gloss of the marks on the surface of the ink. In color printing, the ability of various pigments to absorb UVLED photons is different, and its pass rate is from high to low to M, Y, C, BK, so the degree of solidification of various colors of ink is also different. Through the rate directly affects the energy of photon's inspiration agent, so the printing color order should be arranged as BK, C, Y, M ink with poor light transmittability as much as possible to absorb the photon as much as possible and enhance its solidification effect. Using the wine fine -moisturizing system can reduce the surface tension of ink and promote solidification, and during the printing process, the liquid liquid can be used to strengthen the printing oil dredging area (blank part) The hydrophilic area does not have ink. Improve the ink formula and add the corresponding additives to increase the hydrophobicity of the ink, but excessive hydrophobicity can cause the image edge ink contraction, subtle layers of loss, unclear outlet boundary, etc., affecting the quality of the prints, etc., affecting the quality of the print. UVLED printing requires high surface strength on the surface of the paper, and the surface strength is not prone to pulling hair failure. When printed with gold and silver card paper, due to the smooth surface of these paper, the affinity of ink is less affinity. The second color is printed when the first color is printed. Color ink pull off. Therefore, in the UVLED printing, a paper with a large surface tension should be selected, and the color order should be arranged reasonably to adjust the related process parameters in the printing process to avoid and reduce the occurrence of the above phenomenon.
