Chapter 8 Digital Printing
The biggest difference between digital printing and traditional printing is that the process of printing out paper and printing on paper is omitted. The imaging principle is also different from offset printing. It is suitable for small batches, personalized prints. Fewer, up to 100. If you want to have several books of your own, such as commemorative albums, travel notes, photo albums, etc., the use of digital printing is the most economical and ideal.
The working principle of the digital printing machine is that the charging device charges a layer of charge on the surface of the recording drum, and the dot matrix information of the printer controller to print content (such as characters) is irradiated in the form of a laser beam to the surface of the recording drum that has been charged to put If the recording drum is rotated to the toner cartridge, the charge at the position required by the printing point will attract the toner, and the recording drum with the toner font will rotate until it turns off. At the printing device, the printing paper is located between the recording drum and the transfer device. The stronger reverse charge applied to the transfer device will draw the toner on the recording drum to the printing paper. The heating portion The carbon powder on the paper will be melted and dried, and it will be firmly stored on the printing paper to complete the printing process.
There are three types of digital printing print sizes: A4 (297mm x 210mm), A3 (420mm x 297mm), and SRA3 (450mm x 320mm). Digital printing is suitable for printing paper with a thickness between 80g and 250g.
Digital printing can be applied to a variety of documents. In addition to professional production software, office software and even printed documents can be used. Of course, the most standard is to provide electronic files in PDF format, which will make the printing process quick and accurate. Digital printing can do it right: it's better than others.
