What is the process of book printing?

Printing is divided into three stages:

1, prepress → fingerprinting, which generally refers to photography, design, production, typesetting, output film proofing, etc.

2. Printing → refers to the work in the middle of printing and the process of printing finished products with a printing machine;

3. Post-printing → refers to the post-printing work, which generally refers to the post-processing of printed matter including gluing (laminating), UV, oiling, beer, bronzing, embossing, mounting, binding and cutting. , mainly used for publicity and packaging printed matter.

The production of printed matter generally goes through five technological processes: the selection or design of manuscript, the production of manuscript, the drying of printing plate, printing and post-press processing.

That is to say, the manuscript suitable for printing is first selected or designed, and then the graphic information of the manuscript is processed to make the original (generally called positive film or negative film) for printing or engraving.

Then, a printing plate for printing is made from the original, and finally, the printing plate is installed on a printing machine, and the ink is coated on the surface of the printing plate by an ink conveying system, and the ink is transferred from the printing plate to the substrate by a pressure machine, so that a large number of printed sheets are processed after printing and become finished products suitable for various purposes.

Nowadays, people often refer to the design of the manuscript, graphic information processing and plate making as prepress processing, while the process of transferring the ink on the printing plate to the substrate is called printing. The completion of such a printed matter requires prepress treatment, printing and postpress treatment.

Extended data

Common print elements are:

1. Paper: There are many kinds of paper, which are generally divided into coated paper and non-coated paper. Coated paper generally refers to coated paper (matt copper) and matt paper (matt copper), which is mostly used for color printing; Uncoated paper generally refers to offset paper and newsprint, and is mostly used for printing stationery, envelopes and newspapers.

2. Color: Generally, the relief of printed matter has four colors: yellow, magenta, cyan and black, and there are also printing spot colors.

3. Post-treatment: Post-treatment includes many processes, such as gluing (film covering), UV, oiling, bronzing and embossing. , help to improve the grade of printed matter.
