New technology for die-cutting combination of pinholes in printed matter

When printing a print product that requires an injection hole, according to a conventional production process, the printing process is completed first, and then the print is used to print a pinhole with a special device. However, this kind of traditional craftsman not only has many production procedures, but also takes time and labor, and the quality of the products is not satisfactory: there are many pinhole burrs, which affect the appearance.

To deal with the above drawbacks, the point-line steel knife on the die-cutting process should be used to combine the printing layout with the printing layout. Simultaneously, two steps are used to complete the new process at the same time. This not only greatly improves the production efficiency, but also the product quality. Significant improvement.

The process is described as follows: Before printing, according to the layout size requirements, the point line steel knife cut out the corresponding length, in the bottom section of the side of the point knife, with a hacksaw knife to draw a trace of the appropriate size, so that Using a grinder, straighten the bottom of the steel knife and accurately grind off the excess 0.7mm so that the dotted steel knife is slightly lower than the normal printing height. In this way, when the point line steel knife is in accordance with the specifications of the finished product, and the plate is lined into the printing plate, the height of the spotted steel plate is lower than the printing plate surface, and a certain amount of clearance can be maintained with the ink roller in the normal position, so that the knife blade peaks at the point line. Less than ink, to ensure product quality. As the point-line steel knife is worn down, a certain gap is generated between the point-line knife peak and the drum lining surface, and the normal imprinting contact condition cannot be satisfied.

At this time, as long as the corresponding point in the pressure line marks on the lining, sticking the appropriate width and thickness of the white paper paper strip, you can make the product after the injection hole on the site to produce a significant hole mark, the process effect It is as easy and quick as using the quality of an injection machine. It is worth mentioning that the simultaneous marking of the point knife and the printing plate at the same time must emphasize the maintenance of the accuracy of the ink roller device and the normal adjustment of the ink roller. If the ink roller is eccentric or the shaft hole looses, even if the ink is in contact with the iron roller, it will cause irregular peaks on the point line, which will affect the product quality. Therefore, when printing, we should use a good circle of ink brush ink to ensure the stability of the printing quality.
