When the printing ink is used for reverse printing, sometimes the composite fastness is good, and sometimes the composite fastness is very poor. What is going on? It may be that the concept and ink type are not clear!
The concept of surface printing inks and composite inks (printing inks) varies with respect to dry composite adhesives, that is, the adhesives used in dry compounding are not the usual two-component and single-group When the polyurethane is used, the original surface printing ink may be a composite ink. For example, some manufacturers use acrylate adhesive, and the original acrylate printing ink becomes the printing ink. Strictly speaking, the composite ink should be called a composite ink of a certain composite glue, so that it is complete and clear.
There are many kinds of surface printing inks for polyurethane glue, and there are three main types of commercially available products:
1. Acrylate ink, this kind of ink has no compatibility with PU glue. For example, if this type of printing ink is used for printing in dry curing, it can be easily peeled off on the printing surface after PU compounding;
2. Chloroacetate resin ink, which is an ink made of vinyl chloride-vinyl acetate copolymer as a binder, and has no compatibility with PU;
3, polyamide ink, also known as nylon ink, this kind of ink has some compatibility with PU, such as the use of such surface printing ink printing, there is still a certain degree of composite fastness.
