Flatbed automated screen printing loading system How to solve problems

How to solve problems with FlatBed Automated Creen Printing Loading System? We need to start from those aspects, about the principles of the silk and seal tension, net seal, ink, and glue scraping, please learn about it!

What is tension?

The definition of tension refers to the existence of the internal and interconnected force of the interoperability of the wire mesh when the silk mesh is tensile.

The relationship between tension and mesh

The surface distance between the bottom of the silk network and the surface of the printer is called mesh distance, and the mesh distance plays an important role in the printing process. Adjust the extension of the wire mesh to ensure the transfer effect of the ink. The network distance should not be too high or too low, such as too high, under the pressure of the scraper, or repeatedly stretching and friction in the super elasticity, it is easy to cause the silk mesh to break and produce permanent deformation of plasticity, so that the silk mesh makes the silk mesh Early relaxation affects its life and printing quality. If it is too low, there is no enough return on the silk network, causing the bearing and wire mesh to be cut off, which causes the network version and ink to separate and the ink's transfer rate and clarity, and at the same time, quality problems will occur.

The height of the mesh is determined by the size of the network version and the tightness of the silk mesh. Under the condition that the tension meets the requirements, the general mesh distance is 2-4 mm. With high strong silk mesh, tension is generally below 2mm at 20n/cm.

The relationship between tension and glue scraping

There are three functions during the printing process:

1. Squeeze the ink directly into the mesh and transfer it to the bearing.

2. The glue scraping pressure and the extension length of the wire mesh and the printing effect play a control effect. The glue scraping pressure is endless, and the friction resistance generated during movement movement is large. If the hardness of the glue scratch is insufficient, the glue scraping will be larger. In the case of high glue scraping hardness, the silk mesh may be relaxed and deformed.

When the tension and the pressure of the glue scraping is also large, the friction and resistance produced is also large, which will shorten the life of the silk network version. If the tension is small and the glue scraping pressure is large, the ink will develop, which will cause the printing department to be able Perform normally, causing thicker lines and distortion.

Therefore, a beautiful print must maintain the best ideal tension and glue scraping pressure of silk mesh. Only in this way can we achieve excellent printing effect.

The relationship between tension and possibility

The tension of the silk network has a lot of effect on the accuracy of the chapter. During the color printing, the reflection elasticity of the printing of different tension is different from its elongation, which will cause the chapter error. When the elongation rate is large, the size of the printing version and the size of the printing copy will be significantly deviated. Therefore, the tension of the precise colors printing version must be consistent, and the tension of the same network version must be uniform.

Of course, the tension of the silk printing version is absolutely uniform and consistent. In fact, there are errors that allow a certain range of range. Experts are mistaken for accurate alliances. The error is still acceptable in positive and negative 0.5/cm.

The transfer of tension and ink

In the process of screen printing, the main reason for the separation of Huibaichuan ink and the printing version of the printing is the internal agglomeration (that is, the force to prevent the separation of the ink). The angle of the ink and the adhesion of the ink. Since the adaptation of the ink is much stronger than the adhesion for the ink, the ink can be separated from the wire mesh under the screen tension of the silk mesh and quickly transferred to the bearing material.
