What is the detailed process flow of printing?

Printing is a widely used manufacturing technology, which can print images, characters and other materials on various planes or workpieces. The following are several common printing processes:

Traditional lithography: lithography is a method of printing with flat relief. First of all, prepare the plate, make patterns, bar codes and other contents on the flat copper plate, then ink it, and transfer the printed contents to paper or other media through printing pressure.

Digital printing: Compared with lithography, digital printing uses computer-generated digital images and photosensitive consumables (such as inkjet ink) to complete the printing process in the printer. This printing method is simple and efficient, suitable for small batch printing and personalized customization.

Offset printing: Offset printing is usually used for dot printing (also known as four-color printing), that is, C/M/Y/K inks are printed and mixed for many times to obtain rich color expression. This printing method needs to make a complete offset printing plate first, and then install it on the printing machine. Subsequently, through the separation of ink and wash, it was transferred from offset printing plate to blank paper.

Gravure printing: Gravure printing mainly uses the pattern on the gravure plate to make a triangular cone or rectangular groove, then smears ink inside the groove, and then prints the flattened surface on paper for printing. The depth and number of intaglios can be adjusted to affect the printing effect of the printing plate surface.

The above is a common printing process, and the specific production process and method depend on the characteristics of different printers and printed products.
