Matte oil concentration is unstable

The problem of printing a long version of the work is more prominent. In order to reduce the gloss of UV varnish or water varnish to achieve the matting effect, a large amount of silica needs to be added, which causes the viscosity of the varnish to increase, directly affecting the performance of the varnish. If a debonding agent is added, the curing speed is affected, causing streaks and stains on the coating. Solution: Choose a matt varnish suitable for long-run printing.
