Electronic engraving process

The electronic engraving method is a kind of plate making method that uses an electronic engraving machine to directly sculpt pictures on a plate making roller. It has the advantages of simple operation, low manuscript requirement, fast plate making speed, clear graphics, and rich layers.

The scanning head of the electronic engraving machine scans the original and outputs an electric signal that follows the change of the original to control the diamond engraving needle so that dots of different shades are carved on the surface of the roller. The dot is light and small, corresponding to the bright part of the manuscript; the dot is deep and large, corresponding to the dark part of the original.

The electronic engraving process is as follows:

1. Make a scanning original. Scanning originals can be used to reflect negative images, reflective positive images can be used, usually with a small stretchy white opaque polyester film photographed. If a color plate is used, the original must be a color separation that has undergone color correction and correction.

2. Derusting and degreasing of the plate rollers.
3, the plate roller mounted on the electronic engraving machine.
4. Mount the scanning original on the loading roller.
5, open the engraving machine, engraving plate roller.
