Cups are often encountered containers in people's daily lives, as printing practitioners, we often encounter many customers asking how cups are printed? There are also many kinds of materials for cups, and in view of the length, we will only talk about the printing of plastic cups in this article. In the printing process in the industrial field, except for gravure printing on the cup has not been tried, the cup can be decorated by all other printing methods. For example, offset printing, flexographic printing. Screen printing, pad printing, hot stamping, thermal transfer printing, inkjet printing in special printing are more than extraordinary adaptability. In the mainstream printing field, whether it is flexographic printing or offset printing, the price is very expensive, suitable for the printing of very large quantities of cups, and for small batches of cups, special printing methods are more suitable.
