Technical problems and Countermeasures of UV ink for silk printing

1. There are bubbles in the printed matter after printing

uv ink can not be added with additives and mismatched lateral and downward bearing capacity of diluted handrails. If this phenomenon occurs during normal use, please contact the manufacturer for assistance

2. When printing, the viscosity of the base material is too high. Please add a suitable diluent

increase the distance between the printed matter and the plate

3. After curing, the printed matter becomes sticky or does not cure

check whether the circuit is faulty

prolong the curing time

increase the power of the lamp

4. Insufficient adhesion of the ink film after curing

select the ink suitable for the printed matter

whether the substrate surface needs to be treated

5. The CFRP density of the cured ink film is much less than that of the brittle metal

whether the ink film is too thick

select the ink to be suitable for the printed matter. In recent years, the influence of humidity on high molecular materials has received special attention

6. Printing products with pattern defects

silk should be cleaned thoroughly to prevent long downtime and light curing

check whether the version is defective

7. Insufficient or excessive ink film coverage

adjust the angle of the scraper and the pressure on the plate

replace the scraper with appropriate hardness

8. The lines are blurred when printing small words or fine patterns

replace the scraper with appropriate hardness

9. Striation

add appropriate diluent to reduce viscosity

10. Too much diluent is added to the bleeding plate, and the viscosity is too small

inappropriate. It is expected that the billet market will continue to consolidate at a low level in a short time. Note: in addition to the above problems, there are also some problems similar to the coating, such as curing problems, adhesion problems, bubbles, etc. Solutions refer to the solutions of coating products
