How To Distinguish The Quality Of Uv Printer Varnish

In most cases, when we use UV printers, we go for varnishing. We usually make a back-up view after copying the pattern design to decide whether to go for varnishing. The quality of the varnish also determines whether the pattern is brighter and more beautiful. So we have to know how to judge the quality of the varnish when we buy the varnish, so let's share the relevant knowledge in the next editor!

1. Measure the composition of organic solvents. Put the varnish in a container with a ruler for 10 hours, and check the ruler to find out how much it has evaporated. Good glazing oil generally does not see the reduction of the surface area. If there is a decrease in the area, it indicates that there are more organic solvents in the glazing oil. It is a product that has been previously added with paint thinner.

The editor recommends that everyone choose high-quality varnish as much as possible when buying varnish. The application of high-quality high-quality varnish can make the copied products stronger and stronger. It is recommended to use the varnish sold by the v-printer manufacturer. This is the manufacturer's appropriate varnish after various inspections.

2. Smell the smell. The smell of a good varnish is very small, and its solid content is about 95%. Such a varnish has a small volatile matter and has a small taste after curing.

3. Leveling. We are spraying varnish on the printed matter after the process. Observe whether there are wavy patterns, which indicate that the leveling is not good. Everyone has used it to reduce the viscosity and increase the sizing and curing time.

4. Irritating to the skin. Put a small amount of varnish on the body and observe for 15 minutes up and down. If the skin appears red or blistered, it indicates that the varnish is of poor quality. It is not possible to purchase applications.
