Paper stretch often occurs during printing, we discuss how to control the elongation of the paper
Ling Yun: Paper elongation often occurs during the printing process. We discuss how to control the elongation of the paper.
Xieyi887: The moisture is controlled to the minimum. If it is strict, you can print the water by air, especially for offset paper, so that it is easy to register and extend the paper.
Ling Yun: Try to use horizontal silk paper so that the paper can be stretched to achieve registration by changing the lining
Qjb2008_77: The most important thing is to have good pressure control. It's just water, so be it.
Qjb2008_77: If printing a letterpress on offset paper, generally it is better to run a water first. It is to turn down the pressure a bit, and the water should not be big. If it is a monochrome machine, it is better to print it first and then print it out. Film contrast, look and film sets live, this can be seen that you adjust the size of the pressure hand and discomfort, if the cover of the live, then you can open the printing, so the paper stretching is smaller. This is just the sign Offset paper.
Who are you: The first step is to dry the paper, the second step is to control the temperature and humidity of the workshop, and the third is to control the amount of water and pressure during printing. If it is a monochrome machine, try to reduce the interval between the two colors. Also arrange the printing sequence. Of these, I think these are the most practical.
Hwt314: First of all, we must control raw materials. The longer the date of paper is, the longer the stability of the paper is. The internal stress of the material itself is relatively small, and the moisture content of the paper must be adjusted according to the actual situation. In the south, it is relatively humid and the water content is correspondingly larger. We have used North American paper (dryer) and it is difficult to use. You can also store paper in a printing environment for a certain period of time, or cool paper. Select paper lines when selecting paper. If the paper is not flat enough to knock it. It is certainly a good practice to take the water once, but consider the issue of production efficiency. In addition, look at the color sequence, and put the undesired colors on the front (printing requirements are not high) on the front.
