Paper Properties: Thickness

Paper thickness refers to the thickness of paper or cardboard directly measured under a certain pressure between a pair of measuring boards, expressed in mm or . Paper thickness is a basic performance index of paper, which has a certain influence on the opacity and compressibility of paper.

During offset printing, according to the thickness of the paper and rubber, use the roller eccentric sleeve to adjust the center distance between the rubber cylinder and the impression cylinder. For example, adjust it according to a certain paper standard thickness. The transfer of ink is inconsistent, and the imprint is different in depth, which affects the printing quality.

The uneven thickness of paper has a great influence on the post-processing of printed products. Due to the uneven thickness of the paper during hot stamping, the hot stamping pressure varies from place to place, so the hot stamping effect is also different. The binding also has a great relationship with the thickness of the paper. If the thickness of the paper is inconsistent, the thickness of the spine is not consistent, which seriously affects the quality of the printed matter.
