Flexographic Technology Introduction

The rapid development of flexographic printing has benefited from its own three major characteristics: the environmental protection of water-based inks; the high printing rate and low printing costs. At present, it is mainly used in the field of packaging and newspaper printing. However, it is speculated that the future flexographic printing market will reach a balanced proportion with the lithographic market, which currently has a large occupancy rate. The rapid development of flexographic printing has benefited from the development of flexo printing technology. In prepress plate making, many current RIP manufacturers have added a dot system for flexographic printing in the RIP screening system. And, like the Raithow equipment of Imation company, this kind of function is provided. DuPont's Digital Cromalin software can also use spectral distribution patterns to simulate the various requirements of flexographic printing to produce the best printing version. For the production of flexographic printing plates, there is currently a direct plate making method in addition to exposure exposure. The laser engraving method, this method makes the printing plate more convenient for the user's use. Moreover, the continuous development of the sleeve technology enables the user to make a flexo plate directly on the sleeve. Laser-engraved seamless plates can be used directly on sleeves. In terms of printing equipment, the automatic register control system added to the flexo press has greatly increased the printing accuracy of the flexo printer, and has greatly improved the printing quality and efficiency. Some merchants use an annulus structure where two flexible plates are wrapped around the two rollers, end to end. This structure can reduce the diameter of the plate cylinder, and the distance between the two rollers can be varied by adjusting the distance. The length of the printed image can be changed. This structure increases the flexibility of the roll to accommodate images of different lengths. Allied's flexo presses and Euramex Packaging's Polymark flexographic presses use this structure. Also, there has been a combination printer that combines gravure printing and flexo printing. For example, the FG500 series produced by Comprint, which was mainly produced by gravure printing machines, belongs to this type. This type of printing press can be adapted to the use of more printing materials. Flexo presses are not only in combination with gravure printers, but also in some types such as digital printing devices or rotary screen printing equipment. In this way, not only labels, product advertisements but also packaging products can be printed. Post-printing of finished products can be done online. In order to be suitable for the use of packaging and newspapers, general flexo printers will be equipped with glazing, drying, die-cutting, cutting, rewinding, slitting and other devices behind the printing group. This will greatly increase the operating efficiency of the operator and reduce its labor intensity.
