Make flexographic printing more efficient.

Flexographic printing is the use of a flexible letterpress printing flexible way, it has less investment in equipment, high technology revenue, which will help reprinted wide printing adaptability, easy device operation, high printing efficiency and quality of the printing ink is relatively a series of significant advantages such as stability, and because the process uses environmentally friendly water-based inks for printing, the ink may be better to avoid contamination of print or interior products, therefore, more suitable for printing food, medicine and other packaging products, deep printed by manufacturers and customers, along with the trend of low-carbon economy continues to approach, flexible printing process will be more widely promoted and applied.


Analysis flexographic printing process characteristics.
Flexographic printing plate with the use of the process for the production of flexographic, there are solid or liquid resin plate for plate-making, printing properties of different materials and have different effects print quality. Due to the characteristics of the plate with a flexible, lighter printing pressure, printing adaptability, both thick corrugated board printing, but also thin and soft material printing printing plastic film; either printed strong absorbent paper towels, also can print a non-absorbing material such as aluminum foil. As a result of strong liquidity liquid ink, and the plate is soft and smooth, can better overcome the shortcomings of printed material surface roughness, and then get ink thick, colorful print quality results.

Plate design factors that should be considered.
Because flexographic plate is soft, has a certain elasticity and thickness is relatively large, when the paste on a cylindrical drum, corresponding to the printed version of the portrait of the circumferential surface of the drum would produce a certain bending deformation, especially the larger the plate thickness, surface graphics pasted plate deformation coefficients greater, thereby enabling the graphics and printing out the document size errors. If the print layout of the network structure, dot gain distortion is the main problem caused by printing color deviation.
