1. What is the meaning of postpress processing?
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.
2. What are the types of postpress 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 and decoration processing of the printed surface. 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 Make prints obtain special-function processing. 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 print 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.
3. What is the importance of postpress 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.
4. What is the development direction of postpress technology?
In 1999, China determined that China and the equipment and equipment industry will achieve the â€œ28-character pre-press digital, network, multi-color printing, high-efficiency, multi-press, post-press, high-quality, and serializedâ€ 28-character development policy requirements by 2010. Among them, â€œdiversified and automated after printingâ€ is the technological development direction of postpress.
5. How to correctly understand the meaning of "multiple after printing"?
Post-print diversification refers to post-printing sequence processing, including post-print finishing, bookbinding, and package forming, and is accomplished using a variety of processes and equipment.
6. How to correctly understand the meaning of "automation after printing"?
Postpress automation refers to the widespread adoption of automated and continuous processes and equipment, gradually changing the backward conditions of manual and semi-mechanized production, fundamentally improving the quality of final products and production efficiency, and striving to achieve the general level of advanced countries.
7. What are the development goals of post-press processing technology before 2010?
1 Through the extensive use of a variety of printing products finishing process.
Such as UV coating, calendering, laminating, gluing, waxing, embossing, bronzing, punching, marking, jetting, etc. to improve the gloss, abrasion resistance, corrosion resistance and water resistance of printed products. .
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 internal quality.
3 through a variety of packaging molding process. Such as die-cutting indentation, bronzing, folding gluing boxes, windowing, veneering, compounding, slitting, bag making, etc., to meet the needs of the rapid growth of the packaging market, variety, high quality, short-term cycle.
4 Focus on the promotion and application of glue binding technology, development and improvement of wireless plastic order machines and linked machines, hardcover single machines and linkage lines, and automatic paper cutting machines.
5 Development and extensive application of computer packaging design application software, computer-controlled die-cutting laser cutting machine, engraving machine, and tool forming machine, with emphasis 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 development.
8 After the printing process and materials in accordance with environmental protection, high quality, simple, cheap ideas.
8. What are the main 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.
9. What is the function of surface decoration processing of paper 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.
10. What is the purpose of gloss 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.
11. What are the characteristics of the various methods of paper print gloss processing?
The glossy processing technology for paper prints includes coating coating, infrared drying, coating calendering, polishing, UV coating, UV drying, and various paper-plastic composite coating processes. Each of these methods has its own characteristics and advantages and disadvantages.
12. What is the glazing of prints?
Glossing is the process of coating or spraying or printing a layer of colorless and transparent paint on the surface of printed matter. After being leveled, dried and calendered, glazing will form a thin and uniform transparent bright layer on the surface of printed matter.
13. What is the purpose of glazing prints?
The purpose and significance of the glazing of prints can be summarized in the following aspects: (1) To enhance the appearance of prints. The glazing of prints includes full gloss and partial gloss, as well as high gloss and matt, non-reflective gloss finishes. 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 consumersâ€™ Buying desire.
