What issues should I pay attention to glass ink printing?

Answer:

Reasons for improper clearance between screen plate and glass. The gap between the screen and the glass is not too small, the gap is too small in the printing screen version can not be scraping out of glass, the screen plate is raised, the bottom plate stuck on some ink, it is also easy to cause the paste board;

The reason for the ink, in screen printing ink pigment and other solid particles larger, it is easy to plug the mesh phenomenon. In addition, the mesh size and the area of the hole and the ink particle compared to a small, one of the coarse particles of ink through the mesh and is not easy to block phenomenon is the reason. Because of the larger particles of ink caused by the paste version, you can start from the manufacture of ink to solve, the main method is to strictly control the fineness of ink.

Paste version also known as the blocking version, refers to the screen plate image through hole part cannot will appear in printing ink transfer to the substrate of this phenomenon will affect the print quality, serious and even unable to carry out normal printing. Screen printing process is produced

Reasons for screen printing. The screen plate can be rinsed with water before use and can be used after drying. If the system has been placed too long after printing, it will not be printed in time. In the preservation process, more or less will adhere to the dust, printing if not cleaned, it will cause paste version;

The reason: glass glass surface is not clean, there are watermarks, printed, mimeograph, fingerprints, dust particles and other contaminants. Therefore, the paste is produced; the causes of temperature, humidity and ink properties in the workshop are caused. Screen printing workshop requirements to maintain a certain temperature is about 20 DEG C and a relative humidity of 50% or so, if the temperature is high, low relative humidity, evaporation of the solvent in the ink will quickly evaporate, screen printing ink viscosity becomes high, and through the mesh. Another point should be noted that if the downtime is too long, it will produce paste version phenomenon, the longer the paste version of the more serious. Next, if the environment temperature is low, the ink fluidity is bad, also easy to produce pastes the edition;
