The drying process includes all the processes after ink transfer. In these processes, ink curing is the primary condition for post-press processing and the premise for printed matter to be used in daily life. According to the composition of ink, drying methods can be divided into physical drying, chemical drying, and the comprehensive application of these two methods. The difference between ink and varnish requires different drying systems or the comprehensive application of several drying systems to get the
Several factors affecting the drying effect of printed matter
Printing is the process of transferring the graphic information on the manuscript to the substrate by printing plate or other means, and it can also be understood as the replication process of transferring the coloring agent/pigment (such as ink) to the substrate by using analog or digital image carriers.
Analyze the causes and solutions of slow drying of printing ink
If the ink can be fixed well, it will dry from the inside out. In this case, although the ink surface can resist static pressure after solidification, the ink layer can not resist friction. Ordinary ink for offset printing mainly depends on chemical reaction to dry, and the oxidation and polymerization of ink turpentine are promoted by desiccant and are important components of ink. If the ink is not dry enough to resist the pressure of the next printing color, the paper cannot print the second color. Worst of all, if the ink needs to be dried for a long time, the medium cont
