0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 1. Consider paper type and paper performance
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The effect of paper on gloss quality is mainly reflected in the smoothness of paper The impact of light quality. For high-smoothness paper, the effect after glazing is better, while for low-smoothness paper, the effect after glazing is poorer, because the surface of low-smoothness paper is rougher, and the adsorption of water-based varnish Stronger. In order to solve this problem, you can apply the primer last time before glazing, or glaze twice, or increase the amount of coating when glazing.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; In addition, dimensional stability is one of the key indicators for evaluating print quality It has a close relationship with the amount of water used in the printing process, the moisture content of the paper, the drying time and drying method, and the control of ink viscosity. Generally, thick paper has good dimensional stability and thin paper has poor dimensional stability. If the printed product uses paper with a quantity of 90 g / m 2 or less, please use water-based varnish with caution.

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The printing ink used for the printed products that must be polished after printing, must be It has solvent resistance and heat resistance, otherwise the graphics of the printed product will change color or cause wrinkles, ink skin and other failures after glazing. This requires that when selecting printing inks, alcohol-resistant, ester-based solvents, acid and alkali-resistant inks should be used; inks that are less susceptible to discoloration and good gloss should be used; and water-based varnishes with good adhesion to paper should be selected.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 3. Take the correct amount
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; even and proper amount of water-based varnish coating, gloss Good, high wear resistance. If the coating amount is too small, the water-based glaze cannot form a complete and continuous coating film on the surface of the printed product, resulting in poor gloss and insufficient protection and decorative effects. However, if the coating amount is too large, the coating film is too thick, which will not only increase the glazing cost, but also affect the drying speed. In serious cases, the printed product will stick back. We generally recommend that in order to prevent scratches on the printed matter and enhance the glossiness of the printed matter, the wet coating (or wet stacking) glazing treatment, the amount of water-based glazing oil coating is 2 ～ {{ 6}} g / m 2; if primering before UV glazing, the coating amount is 2 ～ 4 g / m 2; calender finishing In, the coating amount is 10 ~ 2 0g / m 2.
