Abstract

The invention belongs to the technical field of printing, and particularly relates to a method for increasing the oiling amount through printing online oiling. The method comprises the following stepsof: feeding paper on a printer; printing by the printer; and performing online water-based varnish feeding, and applying the water-based varnish to an oil-based functional seat on the printer, wherein an oiling anilox roller is arranged on the oil-based functional seat, the mesh number of the oiling anilox roller is 60-80, and the viscosity of the water-based varnish is 77-95 seconds / 25 DEG C. According to the method, the online water-based varnish feeding step is added, the water-based varnish is applied to the oil-based functional seat, the mesh number of the oiling anilox roller coated with the water-based varnish is set to be 60-80 meshes, and the water-based varnish with the viscosity of 77-95 seconds / 25 DEG C is used for executing the step, so that the oiling anilox roller can effectively carry at least 50 g / m < 2 > of water-based varnish, according to the oiling amount of 10% of the oiling anilox roller transferred to printing paper, at least 5g / m < 2 > of the water-based varnish can be applied to the paper, oil flying and blockage can be avoided in high-speed printing, and it is ensured that the abrasion resistance and folding resistance of printed products are better.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a method for increasing the oiling amount by oiling the printing line. Background technique [0002] Today's society pays more and more attention to low-carbon environmental protection, and green concept printing has been deeply rooted in the hearts of the people. Because water-based varnish has the characteristics of non-toxic, odorless, strong transparency, no emission of volatile organic matter (voc), low cost, and wide source of raw materials, it can endow prints with good gloss, folding resistance, It is wear-resistant and chemical-resistant, and has good environmental protection performance. It is an environmentally friendly material, so it is currently widely promoted and applied in the market. [0003] At present, the flexo printing machine on the market is usually transferred to the paper at a time of 1.3g / m. 2 ~2.5g / m 2 , if off-line oiling is possible, ...
