white cardboard is a kind of strong, thick and quantitative thick paper.

In fact, it is also a kind of paper jam. The most common card does not color, commonly known as white card. If the color, according to the color called color card

high stiffness, bursting resistance and smoothness are also required for the white card paper (except for the white card paper with embossed pattern), and the paper surface shall be smooth, free of streaks, spots and other paper defects, as well as warpage and deformation

single copper paper has bright surface, uniform coating, fast ink absorption, good printability and fine color printing. For the purpose of fine printing, the surface of base paper is coated and polished by super calender

double copper paper is divided into one-sided coated paper and double-sided coated paper. According to the Japanese paper classification standard, the coating amount of each side is more than 10g / m2, which is one of the most commonly used paper types in cultural publishing, advertising design, printing and binding, and instrial and commercial instries

double gummed paper refers to printing paper, also known as offset paper.
