Full Color Inner Frame printing "ghosts" come and go without a trace, eliminate it and print the ink roller to help!

There are two types of inking rollers in the printing press: uniforming rollers and stringing rollers. As the name suggests, the uniforming rollers are used to uniformize the ink. What about the stringing rollers? In addition to the ink distribution function, it also has the following four major functions.

First, it provides power for the ink roller to rotate. Among all the ink rollers, only the ink roller is the driving roller. Driven by the gear, the ink roller drives the other rubber rollers and the plate cylinder under the action of friction. Synchronous rotation ensures that the ink can be transferred to the printing plate synchronously by the plate roller.

Second, it is better to evenly distribute the ink. When the ink roller rotates, it only rotates in the circumferential direction. The existence of the ink roller can not only provide circumferential movement power, but also because of its axial movement, it can also rotate on the axis. Distribute the ink to the string.

Third, the adjustment of the ink supply, because the size of the graphics and text on the printing plate may not be the same, the bite may be large or small, and the ink supply of the ink roller needs to be adjusted according to the layout situation, that is, by adjusting the relative ink roller The starting position of the plate bite is achieved.

　　 Fourth, to reduce the influence of ghosts. What is a ghost? When the distance between the text part and the solid part is just within the diameter of the ink roller, it is very likely that the effect will appear after the printing process. A light mark will appear on the solid part, which is the ghost image often referred to in printing. There are several ways to eliminate ghost images, and increasing the string momentum of the string roller, that is, its axial movement distance, is one of the effective methods.

The existence of each part of the mechanical part of the printing machine has one or more functions. Only by constantly exploring and summarizing in our work, can we be more familiar and understand, and can flexibly adjust and make the ideal Full Color. The Inner Frame For Cigarette product came out, creating greater value for the enterprise.
