subject: Carton Printing Processes Commonly Used Features Of Three Types Of Printing - Paper Box, Printing - [print this page] Carton Products used in the printing process, mainly Offset printing , Letterpress (flexo) and three types of gravure printing processes. These three have their advantages in printed form, so the actual situation according to the factory and product characteristics, Full balance, select the appropriate technology for print production, print production to better reduce costs, increase productivity and printing products in the printing quality.
1. Offset Printing More color offset printing technology group, multi-functional web peace paperboard machine, the former high production rate can be suitable for large-volume print production, product structure and a fixed pre-printed cartons, tissue paper, printing After the production line with corrugated Corrugated paper Direct mounting of plate bonding. Which print speeds up to 10,000 or so per hour, suitable for printing in small batches of carton products, tissue paper, printing specifications can be flexible. Flat-panel models can be directly printed paper, corrugated paper thin, the overlay accuracy should be higher than the former, the quality is relatively more stable. Offset printing ink technology more suitable for trapping or thin overlay of fine lines and multi-color textured version of the printed version, with dot high resolution, print-level layout is rich in tone boundaries clear, soft colors, print reproduction effect, India version made easy, fast, loading, easy-school version of the lower production costs and the plate edge, widely used in color printing pre-printed cartons tissues.
2. Gravure printing process Web gravure printing process has divided the peace paperboard printing, color group has a variety of models and functions, the printing plate technology has higher resistance to printing, printing speed is fast. As the gravure printing ink layer thick, printing ink and full and rich three-dimensional, page printing rich layers, texture strong, fast drying printing ink, is more suitable for large area, thick ink printed products. Gravure printing process can fit the field, spot color line version, but also printing fine textured version, and offset, flexo or screen printing processes such as comparison, the process is not easy to produce the most color printing, carton printing Product quality is the most stable and best. As the gravure Plate After plating of steel roll materials, processing technology such as electric carving handle made of, its plate-making process more complicated, plate material and is also more expensive, and the operation is relatively trouble-for version, it is especially suitable for large number of pre-printed batch carton print production, to better reduce production costs.
3. Flexible printing technology Flexible printing process is also multi-color web printing press of the peace paperboard points, which presses the printing plate of paper tissues in Pre-printer Type, there are direct printing on corrugated board, and can be completed on-line cutting, creasing, slotting the unit. Flexo printing process compatible with the relief, the advantages of lithography and intaglio printing process, as is the flexible printing plate, printing pressure to be much lighter than any other technology, the printing pressure with less, solid ink printing, imprinting a clear anti-Indian plate rate of the main features. The process can print a good surface gloss cardboard, paperboard can print rough surface; can print non-absorbing material, but also a strong cardboard printing absorbent; both print thin paper, thick paper can be printed; both suitable for printing fine textured version of the line version, but also for spot-color print version or on the ground version of the line. Flexo printing plates with rubber version and the version of the sub-resins, rubber version of the main materials are natural rubber and synthetic rubber. The plate has hand engraving, laser engraving and casting plate of three. The use of rubber version, it should be noted printability, such as ink from the rubber pro, transfer ink, covering power and reproducibility considerations, use water-based ink printing, used natural rubber than synthetic rubber plate version material better.
Butyl rubber plates are more suitable for use solvent-based inks. When using nitrile rubber plate should avoid using solvent-based inks, printing plates to be solvent in order to prevent corrosion damage. There is also a rubber version of the shortcomings of easy deformation and cracking, therefore, not suitable for printing fine products. The photosensitive resin plate platesetter technology is simple, its platemaking faster than hand-carving and casting rubber version is much faster-loading easy operation, transfer ink printing plate performance, print quality stable. Better tolerance of the plate, can reproduce high-precision optical network than the level that can reproduce more than 2% of the network and the 150 line of textured print version. Solid resin version of the expansion rate of the liquid resin than the rubber version and a much smaller version, is more suitable for the production of multi-color overlay of the textured version and version lines. However, the solid resin, more expensive version of the price, production costs are relatively high. Therefore, more suitable for printing in large-scale Package Products.
