The characteristics of pre-printed gravure A. advantage of pre-printed gravure the production of color gravure printing pre-printed Carton Can get high-quality, green ink Print Products
Gravure Printing ink than other printing methods on large, Gravure Ink full, ink thickness, with three-dimensional; Color Gorgeous, rich layers, high-definition. In a variety of printing methods, the best printing quality and printing quality is stable. Gravure printing machine machine tension control system stability control, automatic color register control system to ensure accuracy ± 0.1 mm overprint. Gravure printing of each color after the full drying, the printed product stronger. After ordinary gravure printing products screen line up 200L/in, even with the higher surface roughness under the premise of the paper, gravure printing can be very high quality. Pre-printed using water-based gravure printing Ink , Non-toxic pollution, comply with environmental requirements. Currently, domestic production of gravure printed on paper, ink and so is relatively mature, can withstand Corrugated paper Line 200 high temperature and hot-plate friction requirements. Gravure printing and coating can also be varnished once completed.
gravure printing plate pre-printed resistance of high strength, suitable for printing high volume production requirements carton
As Intaglio is chrome plated steel electric carving intaglio, the entire layout from the layer of hard chrome layer of protection, so even when in print layout constant contact with the blade still retains high resistance to Indian forces, generally up to 300 ~ 4 million to India for carton quality, high volume print production requirements.
suitable for gravure printing pre-printed pattern continuous stretch
Offset is to package the prepared plate on the plate cylinder, and therefore, there is always a cylinder surface area for the fixed plate. Intaglio is different version as gravure Plate Operation is carried out directly on the drum cylinder, so as long as the image on the drum to achieve seamless, you can get in the continuous rolling substrate pattern.
gravure printing pre-printed corrugated box production of higher strength
Because of pre-printed corrugated box production is done in the production line, in making corrugated Cardboard Formed when certain heating time, than the traditional method of using veneer machines get higher strength corrugated boxes and printed on the cartons to avoid causing direct damage, enhance and improve the strength of corrugated boxes and punching strength of resistance.
pre-printed gravure printing speed, high efficiency
Because of pre-printed web gravure printing machine by way of printing, each color printing has finished drying device, do not Dusting , Can enter into the next process, the printing speed of up to 150 m / min. High-speed gravure printing process, a roll of material in a short time you can print complete, with non-stop automatic roll changing device Coil Replacement, can greatly improve the printing efficiency. After printing on corrugated cardboard production line well made of corrugated board, than traditional veneer machine much faster.
B. Pre-printed gravure deficiency: Gravure plate-making complex, Make An electric carving intaglio chrome steel drum cycle is generally 5 to 10 days, and higher prices are soft version of the 8 to 10 times; gravure printing of more complex technology, processes more numerous, the entire production line Investment Greater.
(3) the characteristics of flexo pre-print
A. flexo pre-print of advantages: toxic pollution and help protect the environment, is a green printing, food boxes, Drugs Printed in green cardboard box that has a great advantage.
can be printed Large Format Multi-color, high-quality color box. Abroad the most wide-web flexographic printing surface up to 1.8 meters, satellite-based flexographic printing unit could be made into six colors. Can print wide format, multi-color, high quality, high-precision color carton
low cost. Flexo low cost broad consensus has been formed in a foreign country, there are different views in the country. Main is currently used flexo press, flexo plate most of the imports, which led to higher costs. The offset and gravure printing in this relatively low cost. Flexo equipment and plates with and in China Localization Production, the cost will be gradually reduced.
line with different screen printing, print design fine print uniformity. Can be used 100L/in, 133L/in, 175L/in expression patterns, dot delicate, vibrant colors.
tissue paper in corrugated paper and corrugated production line will be mounted a complex bonding can enhance and improve the strength of corrugated boxes and punching strength of resistance.
printing speed and high yield. Satellite-type flexographic printing press of the machine speed can reach 250 to 300 general m / min, to meet a number of automatic corrugated production line needs.
wide range of printing materials, paper from 80 ~ 400g/m2 Dengjun can be printed.
B. Flexo Pre-print of less than
draft of the tone plate process, the design of high-light parts, network polarization was evident, either small network (less than 8% of outlets) had lost time in the burn out and become absolutely network; or network by Dalv too large, as close to the middle tone of the network. Part in the shadows, about 85% of the network will also level, in the ground state. It can be seen to use flexible printing network for AM tone is issued replication can replicate the tone narrower, about 8% to 85%. That is, printing more than 85% of the region, due to dot gain, will produce and class phenomenon, which darkened area lay dead, no hierarchy; print area below 8%, due to network too small, difficult to plate on "Stop." The design of less than 8% of the network, in the actual performance of the printing process is not apparent. Therefore, some multi-layer flexible version of manuscript on the difficult level and presents its rich color.
print screen lines from the point of view, the maximum offset and gravure flexo lines than high. Flexo better screening lines generally 150L/in less than 175L/in, will increase the difficulty of flexo plate making, and also will shorten the life of plate.
not use too small and too small lines of text. As flexo distortion in the printing process will be, so too fine lines, text easily deformed. If the tiny white anti-white or anti-line, as shallow relief, the phenomenon is very likely to lay dead. So try to use a little rough lines, decorative lines and main lines of color contrast to be bigger.
