Two basic principles are generally followed when choosing the number of screens for color coding: 1. It is recommended that the number of screen lines on the color scale be the same as the number of screen lines used in printing operations. This is mainly because the expansion of dots will be affected by the number of screens. The higher the number of screens per inch, the greater the expansion of the dots. Using the same number of screen lines as the actual production to screen the color standard can truly reflect the operating conditions of the printing press, which is consistent with the halftone color separation method. Second, it is recommended that the color standard use a slightly higher number of screen lines than the printing operation. The basis of this principle is that because the number of screen lines is more refined, the color mark is more sensitive to changes in the printing process, which can reflect various changes through dot expansion and dot sharpening faster than actual production. Personnel make necessary process adjustments before the image begins to show visual changes, reducing waste. The number of screen lines between 133 and 150 lines per inch is minimally sensitive to errors. When measuring the color scale, the difference between the method used and the inherent measurement difference on the device can cover any difference brought by the color scale plus the number of network cables. There are currently two different views on the discussion of the shape of dots. Some people think that the color patches should use the same dot shape as the color separation film to provide the best correction. It is also suggested to use round, square and oval dots. Each shape of dot has its own advantages, and the replication difference caused by the shape of the dots is very small, and it is the same as the number of screens. The changes are much smaller than those caused by copying or copying color-coded film. The following methods are recommended: Consistently using the same number of color-coded screen wires is more important than correlating color-coded screen wires with the actual number of screen wires produced. With the continuous accumulation of experience, operators, managers, etc. have begun to link objective measurements with the appearance of images. The use of color codes with different numbers of screens will hinder the understanding of these changes, introduce chaotic factors, and increase the complexity of quality control. When possible, you can use a color scale that matches the actual number of screens. The number of screen lines of the color scale is consistent with the number of screen lines of the dichroic film printed side by side. When measuring, it can be easily connected to each part through the visual appearance of the image, reducing the confusion caused by the difference in screen lines The smallest. The color mark can adopt any dot shape, as long as the dot shape is consistent on all applied films and all objects containing these color patches.
Palletizing capacity:
1, sinolion Palletizing Robot than traditional stacking machine, manual palletizing are much higher;

Whether a color standard with a higher number of screens will be more sensitive to process changes, investigation and research on this issue show that this principle is theoretically correct:
3, the main components of a small number of parts, maintenance costs are very low;
4, sinolion Palletizing Machine arm can be installed in a narrow space, the use of the site of high efficiency, flexible application;
5, all operations can be done in the control cabinet screen touch type, the operation is very simple;
6, palletizing machine arm is very flexible, different products of a machine arm can handle up to 6 production lines. Product updates, only need to enter new data, after the calculation can be carried out, without the hardware, equipment, and set up the transformation;
7, stack type and stacking layers can be arbitrarily set, palletizing neat, convenient storage and transportation.
