The knowledge of printing machine, do you know?

Nov. 15, 2019

Because our products are of good quality and excellent price, they have won unanimous praise from people inside and outside the industry. Now we have a lot of laser printing machine for sale. The digital printing machine and laser printing machine are our hat sale products.

First of all, i want tell you something about the laser printing machine. Laser printing machine. The laser phototypesetting technology originated in the late 1980s and became popular in the mid-1990s. It is a printing output device that combines laser scanning technology with electrophotography technology. The basic working principle is that the binary data information transmitted by the computer is converted into video signals by the video controller, then the video signals are converted into laser driving signals by the video interface/control system, then the laser scanning system generates a laser beam carrying character information, and finally the electrophotographic system images the laser beam and transfers it to paper. Compared with other printing equipment, laser printer has the advantages of fast printing speed, high imaging quality, etc. But the use cost is relatively high, the printer machine price in our company is suitable for everyone. Besides, i want to introduce the work theory to you. Its printing principle is to use a raster image processor to generate a bitmap of the page to be printed, then convert it into a series of pulses such as electrical signals and send it to a laser transmitter. Under the control of the series of pulses, the laser is regularly emitted. At the same time, the reflected light beam is sensitized by the received photosensitive drum. When the laser is emitted, a dot is generated, and when the laser is not emitted, it is blank, thus printing a line of dots on the receiver. Then the receiver rotates for a small fixed distance to continue repeating the above operation. When the paper passes through the photosensitive drum, the colorant on the drum will be transferred to the paper and printed into the bitmap of the page. Finally, after the paper passes through a pair of heating rollers, the colorant is heated and melted and fixed on the paper to complete the whole printing process, which is accurate and efficient.

 At present, digital printing machine is divided into two camps: in-machine imaging printing and variable data printing. In-machine image printing refers to taking the plate-making process directly to the printing machine to complete, omitting the intermediate steps of plate assembly, plate output, plate printing, plate loading, etc. From the computer to the printing machine is a direct process;  Variable data printing refers to the continuous printing of images and texts that need to be changed (so-called data) under the condition that the printing machine does not stop, i.e. the continuous printing of different images and texts on the premise of uninterrupted printing process.
