Technical Communication: A Direct Offset Printing Corrugated Cardboard

Corrugated board directly offset the technical characteristics of

Corrugated direct offset printing equipment in recent years, the main packaging printing speed of development in China at the forefront of the printing industry. The output value in 2005 accounted for 32% of the entire printing industry. Up 12% over the previous year. In packaging and printing industry, color box and they account for a large proportion. With economic development and rising consumption levels, people have become increasingly demanding product packaging, color box to protect not only facilitate the transport of goods and the role of the original goods also require a true reflection of the product packaging, the play shows the quality of goods, to promote sales role. Therefore, the color boxes is a commodity product protection and advertising functions in one, a new vector of commodity promotion. Printing technology is key to the development of color box factors, this article briefly a color box printing?? Direct offset printing corrugated board.

Direct offset printing corrugated board market prospects

Corrugated board printing technology evolved from a simple monochrome text printing to monochrome halftone image printing up to today's color halftone image printing, corrugated box printing toward the high-quality, multi-color, dimension, good visual direction. Currently corrugated flexo and offset printing to gravure most widely in China also have a certain market share. In processing technology and the general mounted again with the first printing, pre-printing and direct printing of ways. First is the first printing and then printed on tissue paper mounted then the composite to corrugated board, then cutting molding. Pre-printing method is the use of web flexographic printing press or web gravure printing machine, printing is still in web form after the closing material, and then printed color face as carton surface web made of corrugated paper, corrugated board production line and then cutting molding. Direct printing is the printing press printing directly on corrugated board. Direct flexo corrugated due to limited equipment and related technology mainly used for the printing medium and low current carton, printing quality needs to be further improved. The direct offset printing corrugated board is quite fast in recent years the development of a printing. As with the equipment and techniques to improve corrugated board has a direct offset mature, can well meet the direct offset printing multicolor corrugated cardboard, high-quality development requirements, while relatively low cost. As a direct offset printing corrugated board technology, which in some areas of the printing corrugated box will gradually replace flexible printing. Direct offset relative to corrugated flexo, offset printing again mounted the first printing has the following advantages:

1. Relative to the flexible printing

high quality printing, you can print out the very fine text and complex halftone images, line screens up to 200 lines / inch.

low cost, low-cost plate offset printing plate, offset the high degree of standardization will also help reduce printing costs. In addition, compared to offset printing equipment flexo printing equipment, small investment, and higher flexibility of the equipment from another aspect of this reduced production costs.

relatively short printing assisted living for the short version is more economical.

performance of various special printable information can obviously improve the surface finishing such as laminating, varnishing, etc., print quality and more stable.

2. Relative to the first offset printing tissue paper and then mounted on the processing method on

corresponding reduction process: eliminating the mounting of the processing operation of the processing costs and materials saved correspondingly. In addition, the entire printing process to reduce the relative shorter processing time and improve the efficiency of processes is also a corresponding reduction in the waste between the same time, labor is also reduced.

Overs less paper. Present, direct offset printing corrugated board, there are some limitations

printing equipment can not be as flexible as can be achieved linkage cardboard production, production efficiency is relatively low.
