   Varnish is a kind of synthetic resin. Now it usually refers to the transparent varnish on the
 
surface. It is made of base materials and additives. It does not add any pigments. It is a kind of
 
paint that does not contain coloring substances. The main ingredients are resin and solvent or resin,
 
oil and solvent. After being applied to the surface of the object, a coating film with protection,
 
decoration and special properties is formed. But varnish also has disadvantages. Varnish is easier
 
to emulsify. As an auxiliary material, varnish has no disadvantages worth mentioning. Because
 
varnish is generally used together with varnish or other paints. So there is no obvious
 
difference after the varnish is applied.
 

   Ink is an important material for printing. It expresses patterns and characters on the substrate by
 
printing or inkjet painting. Ink is composed of resins, pigments, fillers, additives and solvents. It is
 
used for various printing of books, magazines, packaging and decoration, architectural decoration
 
and electronic circuit boards. With the increase of social needs.
 

   Glazing agent is also called glazing wax. It is a paste of beeswax, Brazil wax, etc. dissolved in
 
turpentine. After the surface of the coating film is painted, it can enhance the brightness of the
 
surface, play a role in waterproofing and protecting materials, prolong the service life, increase
 
the appearance of the surface, and improve the color of the paint surface.
 

   Sometimes varnish is added after the ink dries to improve the color, but repelling problems may
 
also occur, so what is the reason? uv ink dryness and ink failure are the main reasons for the above
 
phenomenon. Adding too much drying oil, varnish or tack remover to the ink, or adding anti-adhesive
 
additives such as silicone oil and crystallization of the ink surface, etc., will form repulsion with uv
 
varnish, resulting in inability to coat or uneven coating, and hair loss. Flowers, pitting, pinholes and
 
other phenomena. There is too much dust attached to the surface of uv ink after powder spraying.
 
uv varnish has low viscosity and the coating is too thin. uv varnish has high surface tension,
 
poor wetting, leveling and lipophilicity.
