Device for solving intaglio printing UV varnishing nonuniformity

Abstract

A device for solving intaglio printing UV varnishing nonuniformity comprises a printing ink tank and an ink transfer roller. The device is characterized in that the two ends of the bottom of the printing ink tank (2) are fixedly connected with four stainless steel cylinders (5) of the equal lengths, and compression springs (7) of the equal lengths are installed on the cylinders in a sleeving manner correspondingly; a stainless steel block (6) is installed on the upper portions of every two cylinders (5) at the same end, the compression springs (7) are made to tightly eject the lower bottom faces of the stainless steel blocks (6), and the spring force is made to act on the stainless steel blocks (6); and the ink transfer roller (9) is installed at the middle positions of the two stainless steel blocks (6) in a rotating manner. During work, a printing plate is not soaked in printing ink, the water filter sleeve ink transfer roller is soaked in the printing ink, the printing plate and thewater filter sleeve ink transfer roller are close together, the printing ink is transferred to the printing plate through the water filter sleeve ink transfer roller, and in this way, the varnishingnonuniformity problem caused by bubbles to the UV printing ink is solved.

Description

technical field [0001] The invention relates to a device for solving uneven UV glazing in gravure printing. [0002] technical background [0003] With the improvement of people's requirements for the appearance style and quality of commodity packaging, from design paper to production printing, the process technology is becoming more and more complicated, especially the printing is more complicated than before, from the original single-color printing to the later multi-color printing, and then Up to the current multi-color overlay printing, or several kinds of printing on the same package, the last color of printing must be varnish to protect the previous printing. The varnish has also changed from the original oily varnish to the later water-based varnish, and then to the current UV varnish. UV varnish contains almost no solvent, very little organic volatile emissions, and strong adhesion; the surface of printed matter after UV varnish is more wear-resistant, has the charac...
