Classification of calendar printing by use, number of colors and plates
Print classification methods come in many forms. The use of printed matter can generally be divided into book printing, packaging printing, advertising printing and seed printing; according to the number of printing colors, it can be divided into single-color printing and multi-color printing; according to the type of printing plate, it can be divided into letterpress printing, gravure printing, Lithographic printing, stencil printing. Because the type of printing plate is closely related to the printing process and can better reflect the characteristics of various printing methods, the classification of printing plates is the most common.
In the printing process, printing is generally divided into two categories: pressure printing and pressureless printing. Due to the continuous emergence of new materials, people’s various demands for printing are increasing day by day. Sometimes the method of pressure and pressureless printing cannot achieve copying and conversion, and special printing emerges as the times require.
