The imaging principle is also different from offset printing. It is suitable for small batches and personalized prints. It can be as few as 100 parts. If you want to have several books of your own, such as commemorative books, travel notes, photo albums, etc., digital printing is the most economical and ideal.

The working principle of the digital printing machine is that the charger charges a layer of charge on the surface of the recording drum, and the dot matrix information of the content (such as characters) to be printed by the printer controller is irradiated to the surface of the charged recording drum in the form of a laser beam to release Remove the charge at all positions that are not required by the printing point. When the recording drum rotates to the toner cartridge, the charge at the position required by the printing point will attract the toner. When the recording drum with the toner shape rotates to At the printing device, the printing paper is between the recording drum and the transfer device. The stronger reverse charge added to the transfer device will attract the zigzag toner on the recording drum to the printing paper. The heated part The toner on the paper will be melted and dried, and the glyphs already on the printing paper will be firmly stored to complete the printing process.
