Postpress Technology Basics Q&A

Printing technology is a systematic project, which is mainly divided into three major processes: prepress, printing, and postpress. Postpress is a general term for the production technique of obtaining the final required form and performance of the printed sheets printed by the printing press.

What are the types of post-press processing that can be classified according to the purpose of processing?

Printed products are a general term for various products produced using printing technology. Printed post-press processing can be divided into three categories according to the purpose of processing.

1 The beautification of the surface of printed materials. For example, to improve the glossiness of printed materials, coating or laminating processes; to improve the three-dimensional impression of printed materials, such as embossing and embossing or crystal three-dimensional plastic drop processing; to enhance the flicker of printed products, such as refraction and hot foil processing.

2 Get the print to get the processing of a specific function. Prints are for use by people. Different prints should have or strengthen certain aspects of their functions, such as oil, moisture, wear, and insect protection, because of their different services or purposes. Some prints should have a certain specific function, such as the tearing of stamps, introduction letters, etc., documents, forms, etc. can be rewritten, magnetic cards have anti-counterfeiting features.

3 Printed material processing. Such as single-page printed to the design of the size of the provisions of the size of the books and magazines bound; packaging materials, such as die-cutting indentation processing.

What is the importance of post-press processing?

Printed matter is a comprehensive product of science, technology, and art. Whether or not a printed matter makes readers pleasing to the eye and can not put it down, apart from the content, it depends on the exquisite manuscript design, the lively arrangement of layouts, the vividness of color deployment, the elegantness of decorating and processing, and so on. Give prints inspiration from the United States.

Today, people are increasingly demanding the appearance of prints. The main way to meet this demand is to finish the printing process, and to improve the quality of printed products through decoration and decoration. According to statistics, good packaging can increase sales by 15% to 18%. The investment in finishing costs after printing is far lower than the added value of product added value, product promotion rate, and safety and convenience. Post-press processing is an important means to ensure the quality of printed products and realize value-added. Especially for packaging and printing products, many of them use post-press processing technology to greatly improve quality and increase their special functions. In a sense, post-press processing is the key to determining the success or failure of printed products, often due to the quality of post-press processing, resulting in the predecessors of printed materials.

What is the development direction of postpress technology?

In 1999, China determined that China and the equipment and equipment industry will achieve the “28-character pre-press digital, network, multi-color printing, high-efficiency, multi-press, post-press, high-quality, and serialized” 28-character development policy requirements by 2010. Among them, “diversified and automated after printing” is the technological development direction of postpress.

What are the development goals of post-press processing technology before 2010?

1 By adopting a wide range of printing finishing techniques such as UV coating, calendering, laminating, gluing, waxing, embossing, bronzing, punching, marking, and spraying, etc. Gloss, abrasion resistance, corrosion resistance and water resistance.

2 Through the extensive use of automated, continuous production of high level of folding, page allocation, lock line, paper binding, binding, saddle stitching, hardcover, cutting, packing and other equipment, improve the appearance of books and products and intrinsic quality.

3 Through a variety of packaging molding processes such as die-cutting indentation, bronzing, folding gluing, windowing, veneering, compounding, slitting, bagging, etc., to meet the rapid growth of the packaging market, variety, high quality, short cycle Demand.

4 Focus on the promotion and application of glue binding technology, development and improvement of wireless plastic order machines and linkage machines, hardcover single machines and linkage lines, and automatic paper cutters.

5 Develop and widely use computer packaging design application software, computer-controlled die-cutting laser cutting machines, engraving machines, and tool forming machines, focusing on improving die-cutting accuracy and die-cutting processing speed.

6 Application and development of high-precision, high-speed multi-functional printing and post-press production lines.

7 Post-press processing equipment is moving toward automation and in-depth direction. The printed process and materials are developed according to the environmental protection, high quality, simple and cheap ideas.

What are the major types of surface decoration of paper prints?

Paper print refers to a product that uses a variety of printing methods to form ink-colored graphics on the surface of a paper substrate. The surface decoration process of paper prints mainly includes: surface gloss processing of printed materials, processing of gold and silver luster on the surface of printed matter, processing for improving the three-dimensional surface of prints, and processing of special gloss for prints.

The surface decoration of paper prints is the icing on the cake. Through the decoration process, the appearance effect of the printed matter can be improved and improved, and the effect of beautifying can be achieved. Through surface decoration and processing, printed materials are colorful, or gentle, or magnificent, or colorful, or unpredictable, not only increase the added value of products, but also enrich the diversity of print.

What is the purpose of glossy processing of paper prints?

Prints show their value through surface graphic prints. The so-called print quality is actually a comprehensive evaluation of the visual effects produced by people's prints. The gloss of the prints can enhance visual effects and become an important factor affecting the quality of prints.

Glossy processing technology of paper prints, including coating glaze, infrared drying, coating calendering, polishing, UV glazing, UV drying glazing, and a variety of paper-plastic composite, film, and process. Each of these methods has its own characteristics and advantages and disadvantages.

What is the glazing of prints?

Light is printed or sprayed on the surface of the print, printed with a layer of colorless and transparent paint, after the leveling, drying, calendering, and then formed on the surface of the print thin and uniform transparent bright layer of processing.

The purpose and significance of the glazing of prints can be summarized in the following aspects: (1) To enhance the appearance of prints. Glossing of prints, including full gloss and partial gloss, also includes high-gloss and matt-type, non-reflective gloss, and gloss. Either way, it can improve the appearance of prints, make the print texture more full and full, brighter and brighter colors, improve the gloss and artistic effects of prints, play a role in beautifying, make products more attractive, and enhance consumers’ Buying desire.
