What is the classification of gravure presses and gravure presses?

Conventional printing presses are no longer accustomed to the development of the age, in order to get used to a certain demand, we need a gravure printing machine. But before using the gravure press, we must have a certain understanding of it. Then, let's introduce you to what is the classification of gravure presses and gravure presses.

When printing on the gravure printing machine, the ink in the blank part of the plate is scraped off with a squeegee to leave the ink in the graphic part, and then the paper is embossed on the back side of the paper by the impression cylinder, so that the ink of the concave part is directly Transfer to the paper surface, and finally the printed matter is piled up or re-rolled through the delivery section.

According to the plate making method, it is divided into two categories: embossed gravure and corrosion intaglio.

(1) Mechanical engraving gravure

The mechanical engraving gravure is made by mechanically manipulating the knives on the outer surface of the plate cylinder. It reduces the repetition and cumbersome labor of the craftsmanship. The plate making speed is faster, the cycle is shorter, and the plate making cost is lower.

(2) Craftsmanship

The hand-carved engraving gravure is made by a technician using a knives on the outer surface of the plate cylinder according to the original artwork. The plate material can be made of copper or steel. Craftsmanship is cumbersome, the cost of plate making is large, and the cycle is long. However, the gravure lines of the craftsmanship are clear, and the printed matter has a strong sense of hierarchy and is difficult to be faked by others. Mostly used in the production of printed intaglios for securities and high quality art.

(3) Electronic engraving gravure

This version is mainly controlled by an electronic control device to sculpt the surface of the plate cylinder. Using the electronic engraving machine, according to the photoelectric principle, the engraving knives are controlled, and the cells are carved out on the outer surface of the drum, and the area and depth thereof change together.

Things must keep pace with the times, we must learn to use better products in a more suitable place.
