The factors that determine the material in the printing of ceramic flower paper

1. Selection of screen

Printed fine patterns generally use 120-140T or S-type yellow, orange mesh; when you need a thick layer of color can be used when the 100-110T domestic mesh.

2. The tension of the screen

The importance of tension is reflected in two aspects. The screen tension of the ceramic flower paper is set to 18N/cm, and the mesh surface is flat and strong. When the photosensitive adhesive is coated, a uniform coating is easily obtained, and the resulting image is ideal. There will be inconsistent images in the middle and around. When the screen tension is less than 15N/cm, the printed pattern will be elongated. If the pressure of the blade is slightly larger, the accuracy of the color registration will be seriously affected.

3 photosensitive material

It is the second foundation for screen printing, and the screen is the first basis. If only good screens do not have good photosensitive materials, it is impossible to print good images. The use of domestic sensitized adhesives can be used to print general products. Foreign sensitized adhesives are more expensive, but they can make good screens.

4. Ceramic flower screen printing ink

It is made by mixing ceramic powder and varnish, and the volume of varnish affects the smoothness of printing and affects the depth of hue. The proportion of varnish and toner is not fixed, about 7:10, and detailed records should be made. In addition to quick drying and slow drying, the types of varnish are specially designed for the printing of large area patterns and for thixotropic printing of hierarchical dot pattern. The rogue type varnish is widely used. The thixotropic varnish is specially designed for the screen printing of the precision pattern. Its characteristic is that the dots printed by the screen are relatively fixed, and are not as easy as the rogue type ink. The dots are linked together due to the enlargement of the print, causing the image to be blurred. Rogue type varnish is characterized by its small amount of adjustment, easy to get dark results.
