Book printing process is?

Printing is divided into three stages:

1, pre-printing → refers to the work of the pre-printing, generally refers to photography, design, production, typesetting, output film proofing, etc.;

2, printing → refers to the mid-printing of the work of the finished product through the process of printing presses;

3, printing → refers to the work of the printing of the later stage of the work of the printing of the printed matter generally refers to the post-processing of printed materials including over-gluing ( Laminating), UV, oil, beer, hot stamping, embossing, laminating, binding, cutting, etc., mostly used for promotional and packaging prints.

The production of printed matter, generally after the original selection or design, the original production, printing plate tanning, printing, post-press processing and other five processes.

That is to say, the first selection or design of the original manuscript suitable for printing, and then the original graphic information processing, production for the tanning or engraving plate plate (generally called the Yangtu or Yintu negative).

And then use the original plate to make printing plates for printing, and finally the plate installed in the printing machine, the use of the ink delivery system will be coated with ink on the surface of the plate, pressurized by the pressure machinery, the ink will be transferred from the plate to the substrate, so that a large number of replicas of the printed sheet, after printing processing, it will be adapted to the purpose of a variety of use of the finished product.

Now, people often the original design, graphic information processing, plate making collectively referred to as pre-press processing, and the ink on the plate to the substrate on the transfer process is called printing, so that the completion of a print needs to go through the pre-press processing, printing, post-press processing and other processes.

Extended information

Common printing elements are:

1, paper: paper classification is many, generally divided into coated paper, uncoated paper. Coated paper generally refers to coated paper (light copper) and matte powder paper (non-glossy copper), mostly used for color printing; uncoated paper generally refers to offset paper, newsprint, mostly used for letterhead, envelopes and newspaper printing.

2, color: general print is embossed by yellow, magenta, cyan, black four colors, in addition to printing spot color.

3, post-processing: post-processing includes many processes, such as over-gluing (lamination), over UV, over-oil, hot stamping, embossing, etc., which helps to improve the grade of printed materials.
