The installation of the printing plate should be in accordance with the specifications of the plate, and the appropriate backing paper can be printed to print the originals that are loyal to the original. However, how to correctly and quickly correct the printing plate is a necessary technology for the entry technician. Today, thanks to the blessing of printing technology, after the successful development of the cross-hair punching device, the previous set of plates must be completed in a dozen or twenty minutes under the adjustment of skilled printing technicians, but now it is greatly Shortened, the principle of its invention is to integrate the school-based technology that was previously regarded as the master's entry, that is, to work on the printing plate of the four-color crosshairs, and to move it out from the narrow space of the printing machine. On a platform puncher, the plate after the hole is finished can be installed on the plate of the printer by using the remote control device of the printer. It is very simple to make some adjustments, but the school plate technology is also labor-saving. After the successful development of chemical equipment, some traditional techniques are gradually neglected by a new generation of printing technicians. Here, the school edition technology is re-introduced. Although it is somewhat contrary to printing technology, the principle of the tube design and the school edition technology are intriguing. Think of the past printer In addition to the sharp ability to distinguish colors, it is also necessary to have both hands and feet. However, the hand and foot of the cockroach can be known by the speed of its school version. This technique naturally becomes the skill of Master's eating, and it must become a practice before the general apprentices get started. Important subject. Let us discuss the principle of this school technology one by one!
First of all, you need to know the number of threads of the screw on the plate, that is, the pitch of the screw. Usually, the screws with the 17 or 19 wrench as the calibration tool are 0.75m/m, 1.0m/m, 1.25m/. m or 1.5m/m pitch, but the printing tube manufacturing company's plate design is different. The printing master does not rotate the school plate screw when making the plate correction. Master adjusts just because of his feeling but how to handle it. You must be right, you have to be a master after you read this report (I didn’t want to learn the door before, Master’s school work is afraid of being taken away and still wearing a rag to cover up) Example No. 17 Wrench For a screw of 0.75 m/m, the screw rotates one turn (one rev) to produce a displacement of 0.75 m/m, and one turn is 0.125 m/m; that is two turns (two rev) = 12 angles (12 take), the plate displacement is 1.5m/m. Understand this design principle, pay attention to the parallel principle of the printing plate (pull the three take, remember that the opposite top to side of the three take the same reason, vice versa As long as you will base the four calculations, the calibration of each set of plate rules is fast and accurate through the brain calculation, then the school technology It is no longer a secret after a rag.
