Coated paper and coated card are often used
in book printing,
so what's the difference between coated paper and coated card? Generally
speaking, coated paper is lighter and thinner than copper card. The quality of glossy
cardboard is better. In terms of use, the two are also different.
Coated paper, also known as coated printing
paper, is called powder paper in Hong Kong and other regions. It is a
high-grade printing paper made of base paper coated with white paint. It is
mainly used for printing covers and illustrations of high-grade books and
periodicals, color pictures, all kinds of exquisite commodity advertisements,
samples, commodity packaging, trademarks, etc.
Coated paper is characterized by very
smooth surface, high smoothness and good gloss. Because the whiteness of the
coating is more than 90%, and the particles are very good, and it is calendered
by super calender, so the smoothness of coated paper is generally 600 ~ 1000s.
At the same time, the coating is evenly distributed on the paper surface, showing
a pleasing white. The requirements for coated paper are thin and uniform
coating, no bubbles, appropriate amount of adhesive in the coating, to prevent
the paper from dusting during book printing, in
addition, the absorption of xylene of coated paper should be appropriate.
The following are the detailed differences
between coated paper and coated card:
