Abstract: In the normal ink, varnish, and packaging printing or post-printing finishing technology, some people always attribute the secondary waste problems appearing on packaging printing to the quality of the substrate or the ink or coating oil (commonly known as coating ) The quality of low energy or fitness is not good. The reason why printers shirg their responsibility in a straightforward manner is related to their lack of scientific and systematic learning and mastering of packaging printing technology and finishing technology.

In normal inks, varnish and packaging printing or post-printing finishing technologies, some of them simply attribute the sub-scrap problems appearing on packaging printing to the quality of substrates or the quality of inks or coating oils (commonly known as coatings). The low energy or fitness is not good. The reason why printers refrained from responsibility in a straightforward manner is related to their lack of scientific and systematic learning and mastering of packaging and printing technology and finishing technology.
Through nearly 30 years of tracking services for ink production and printing operations throughout the country, the author summarized nearly 16 technical defects and remedial solutions. The practice proved the performance of inks or coating oils, the nature of substrates, and the Skills are the three major causes of technological defects. In order to solve these problems, I will talk about my own views from the following eight aspects.
Second, there are three major shortcomings of ink or varnish products:
1. Precipitation, precipitation, gelation, thickening, thickening, thickening, crusting, hair growth, color mixing, discoloration, discoloration, color, filler and precipitation often occur during the production and storage of packaging printing inks and coating oils. Caking. Poor pigment dispersion, poor resin compatibility. Incorrect solvent blending, pigment production, storage, bloating, gels. These defects severely hinder normal ink production, storage, and use.
2. There are sag, ink film whitening, bleeding, floating color, graphic and texturing, deformation, ink film softening, cracking, orange peel, wrinkle, non-flatness, bite during the process of packaging, printing, coating and finishing. Bottom, cross-color, shrinkage, shrinkage, pinholes, blisters, side rainbow, yellow, fade, and more.
3. Discoloration, fading, chalking, cracking, peeling and peeling of the ink layer, blistering, spoilage, pinholes, blooming, fogging, and the like often occur after the printing and post-printing finishing.
Before and after the two are mainly related to the quality of packaging printing inks or coating oils, and the middle is mainly related to the quality of inks or coating oils, and the design of printing and finishing processes, quality management of finishings, printing, and finishing environments. Therefore, the development and production personnel of ink and varnish must understand the difference between package printing and finishing products. The production process and environmental requirements are different, and the selected ink or varnish is different. For example, different temperatures in spring, summer, autumn and winter, different humidity in coastal and plateau, differences in sunny weather and rainy season, differences in printing machinery or finishing and coating machines, and differences in drying (infrared, ultraviolet, etc.) conditions may cause defects. It will not be the same.
