Ask the knowledge of the printing factory.

1: Microcomputer operation for typesetting and publishing. Pay attention to the size of printed pages, whether there is enough bleeding, whether printed film or CTP is printed with light characters, and ensure that the blank part is completely clear when ps plate is exposed, and the dot imaging does not change much and cannot be lost.

2. In the operation of the printing machine, the printed matter should be basically consistent with the original as far as possible, such as color brightness, depth, etc., to ensure that the finished product has enough printing loss, including the following processes, to prevent printing from returning to work.

3. Bookbinding products can be roughly divided into two categories, books and periodicals and packaging.

Books and periodicals include folding, page matching, binding (binding, wire binding, sewing, etc.), cutting finished products and packaging. When matching pages, pay attention to whether there are missing pages, wrong pages and correct page number sequence, whether there are missing pages when binding, the depth of back milling, the fullness of glue hanging on the back glue, whether the back glue is squeezed into the side glue part when clamping the back, and pay attention to the size of the book when cutting to avoid skew and inconsistent sizes.

General packaging printing plants only have business packaging, not carton packaging. There are many brochures and pages in commercial packages. The finished products of books are the same as books and periodicals, only pay attention to the pages when cutting.
