Printing technology is a systematic process, mainly divided into three major stages: pre-press, press, and post-press processing. Post-press processing refers to the production techniques that give the printed sheets their final desired form and functional performance after they come off the printing press.

Beautification and decorative processing of the surface of printed materials.For enhancing the glossiness of printed materials, processes like varnishing or lamination are used. To improve the three-dimensional effect of printed materials, embossing and debossing are applied. To add a shimmering effect to printed materials, gold and silver foil stamping are utilized.
Processing to give printed materials specific functions.
For example, making printed materials resistant to oil, moisture, wear, and insects. Some printed materials should have specific functions, such as being tearable for circulars, envelopes, and letterheads, or having the ability to make carbonless copies like NCR paper.
Shaping and forming of printed materials.
For example, trimming single-page printed materials to the design-specified size; binding books and magazines; and die-cutting and creasing packaging materials.

Printed materials are a combination of science, technology, and art. Whether printed materials are pleasing to the reader and irresistible depends not only on the content but also on the exquisite design of the drafts, the vivid layout arrangement, the bright color coordination, and the elegant and generous decoration processing. It is essential to give printed materials a soul of beauty.Nowadays, people's requirements for the appearance of printed materials are getting higher and higher. The main way to meet this demand is to carry out exquisite processing of printed materials, enhancing their quality through decoration and embellishment.
