Wood pulp carbonless copy paper is one of the common papers in daily life. It has been widely used in different industries, but the paper is still very different from ordinary paper, so there are many needs to use wood pulp carbonless copy paper. Pay attention to the problem.

Wood pulp carbonless copy paper is a kind of invisible paper, which has the function of direct copying and direct color development. Its color development is mainly: under the action of external force, the force-sensitive pigment and oil solution in the microcapsules overflow and come into contact with the color developer to cause a dyeing reaction, thereby playing the role of copying.

Wood pulp carbonless copy paper is a very versatile product. When buying, try to buy the same brand for the upper, middle and lower layers of paper, so that the ingredients will be the same and there will be no color difference. And the production date should not be too long apart, because the products of different manufacturers have different indicators such as whiteness, color rendering optical density, smoothness, thickness, stiffness, printing surface roughness, color paper tone, tightness, ink absorption, etc. The same, so be sure to buy products from the same manufacturer that do not have a long date interval.

Pay attention to the surface strength to determine whether or not to shed powder, lint, and produce paste; high opacity of carbonless copy paper can reduce print-through; good paper evenness can reduce printing wrinkles; smoothness determines printing pressure and ink consumption.

Characteristics of wood pulp carbonless copy paper The upper paper has a coating underneath, the middle paper has a coating on both sides, and the lower paper has a coating. Therefore, pay attention to the directionality when using it. If it is reversed, it will be impossible to copy. Excessive wetness will cause deformation of the base paper and damage to the coating, making it impossible to rewrite. Too low a temperature will affect the color rendering speed, but will not affect the color rendering effect.
