How much do you know about uv ink?How to improve the scratch resistance of
uv prints? After confirming that the uv ink is completely cured and has good
adhesion, if the scratch resistance of the uv print does not meet the customer's
requirements, it is recommended to polish the print first to protect the ink layer
surface; Secondly, if there is no subsequent processing technology for uv prints,
you can consider adding appropriate enhancers to the uv ink to increase the
smoothness of the ink surface and meet the scratch resistance requirements.
In addition, uv ink with fast curing speed and excellent scratch resistance can
also be selected to fundamentally solve the problem.
How much do you know about uv ink?Compared with ordinary ink, why is uv ink
more difficult to control when printing? Why is the gloss of uv printing poor? uv ink is
essentially different from ordinary ink. The binders in ordinary inks are modified
substances such as rosin resin or soybean oil, which have good wetting and dispersion
properties for pigments. However, the main components of uv ink are modified
polyester binders and acrylic monomers diluents, which lack the wettability and
dispersion of pigments, resulting in poor ink mobility and transfer,
which makes uv printing more difficult to control.
How much do you know about uv ink?In addition, in terms of the gloss of printed
matter, ordinary ink itself has good fluidity and transferability, and the natural
gloss of printed matter is good. In addition, the drying process of ordinary ink
depends on the combination of volatilization, oxidation of conjunctiva, and penetration.
The drying process is relatively slow, which gives the pigment time to
"wet and rearrange", thus improving the gloss of printed matter. However,
the uv ink can be completely cured within 1 second, and its own liquidity is
insufficient, so the gloss of the printed matter is not very high.
