The factors that affect glossing are paper properties, ink, temperature, and crystallisation:
(1) The smoothness of the paper is low and the gloss effect is poor because the gloss oil is absorbed by the rough paper surface. To solve this problem, you can have a casein base or two lights before you polish.
(2) The inks that require post-printing must be solvent-resistant and heat-resistant. Otherwise, there will be discoloration or wrinkling of the graphic information of the printed matter. When selecting printing inks, care must be taken to select alcohol-resistant, ester-based solvents. Acid-base ink. To select inks that are good for paper absorption. Use long-lasting, color-changing inks.
(3) The glazing temperature is between 18-20°C and the effect is good. In winter, the temperature of the coating oil is low, and the varnish is easily solidified, which causes the varnish on the varnish surface to be uneven and can be diluted with an appropriate amount of solvent.
(4) Crystallization Imagination is mainly due to the fact that the prints have been placed for too long, the ink area at the bottom of the print is too large, and the dry oil has been excessively added. To solve this problem, 5% lactic acid can be added to the varnish and used after mixing.
