1. Letterpress printing

 

In fact, the principle of letterpress printing is like a stamp. The part with text and images is raised upwards, the part without images is recessed, and then the raised parts are colored and printed directly on the paper. Letterpress printing is difficult to make, and it is difficult to grasp the uniformity of oil and ink when coloring. The printed sheet should not be too large, and it should not be over-opened. Moreover, as the number of printing times increases, the layout will continue to wear away, which limits the number of prints.

2. Lithography

 

Those who are familiar with lithography also know that it is also called offset printing. It is indirect printing, which was developed from the early lithography. The lithographic printed part of Shanghai box printing has no unevenness between the printed text and the unprinted text, which are all on the same plane. It uses the principle of immiscibility of water and oil to attach a patterned part to a layer of oil film rich in oil, while the part without characters and patterns absorbs water and forms an anti-ink effect.

 

Lithographic printing has basically no restrictions on color setting. The ever-changing colors can be overprinted by CMYK (CYAN blue, MAGNTA magenta, YELLOW yellow, BLACK black). Generally, lithographic printing is simple, low cost, good quality and suitable Mass printing.
