Problems solved by technology

[0002] When printing transparent ink (also known as varnish) on printed matter, since transparent ink is generally printed on colored patterns, in order to ensure product quality, it is usually necessary to take out the printed materials that have passed the machine for the first time for inspection. When printing graphics and text effects, it is often necessary to swing the product at different angles to judge whether the transparent printed pattern is complete and whether the effect is normal. Since the transparent printed lower layer pattern usually has more textures and colors, this inspection method is extremely difficult, and Often easy to miss, imprecise, unable to ensure the integrity of subsequent products

Abstract

The invention provides a method for detecting a gloss oil printing process. The method specifically comprises the following steps: after a plate material is loaded on a machine table, black card paperis taken to pass a machine; then whether a pattern printed by transparent ink on the black card paper is complete or not can be judged through naked eye observation; and when the pattern is complete,the pattern is qualified. The detection method disclosed by the invention is adopted for detecting the gloss oil printing of the plate material, and whether the gloss oil pattern is complete or not can be rapidly judged, so that the stability of subsequent production can be ensured, and the product quality can be ensured.
