The influence of paper on the gloss of printed matter

The main factors affecting the gloss of printed matter are the surface smoothness, ink absorption and gloss of paper.

      In the packaging and printing industry, the gloss of paper is determined by the flatness of paper surface, which is related to the type of fiber, the degree of grouting and calendering, the content ratio of filler and sizing material and sizing method.

     The main factors affecting the gloss of printed matter are the surface smoothness, ink absorption and gloss of paper.

The influence of paper on the gloss of printed matter

       The surface smoothness of paper refers to the time required for a certain area of paper to deflate under a certain pressure, in seconds (s).The influence of paper on the gloss of printed matter

      The surface smoothness of various papers is different. Ordinary paper with smoothness below 80s is low smoothness paper, above 80s is medium smoothness paper, and 300 ~ 600s is high smoothness paper.

     For example, the smoothness of coated paper is 800s, and the surface gap of paper is 2.5 μ M or so. The smoothness of domestic 150g / m2 super grade double-sided coated paper is 500s, while that of foreign coated paper with the same gram weight is more than 1000s.

      Domestic 150g / m2 high-grade art coating paper, with smoothness of about 100 ~ 1500s, is the paper with the highest smoothness standard in China. In fact, the size of the paper surface gap is the size of the paper surface gap, and the smoothness is more than 1000s. Therefore, the smoothness has a great influence on the gloss of the finished product.The influence of paper on the gloss of printed matter

      The paper with high smoothness has good contact with ink, which can ensure the complete reproduction of dot and make the finished product have better luster. After the ink is transferred to the paper surface. The influence of paper on the gloss of printed matter

     The surface flatness of the ink film formed on the paper is also relatively high, and a certain “specular reflection” is formed after light irradiation;, Show a certain brightness.The influence of paper on the gloss of printed matter

      On the contrary, the paper and printing ink film with poor smoothness and rough surface are uneven, the light can only form diffuse reflection, and the finished product lacks luster.

 The ink absorption of paper refers to the absorption performance of paper to ink connecting materials.

     The coarser the paper, the larger the fiber gap, and the stronger the absorption capacity of the connecting material. Different types of paper have different ink absorption.The influence of paper on the gloss of printed matter.

      When the ink layer is dry on the paper, after a large amount of ink connecting materials are absorbed, pigment and other particles float on the printing surface to form diffuse reflection and can not produce luster. 

      The ink absorption of paper is too small and the penetration of connecting materials is less, which can obtain printing with bright colors and high gloss.The influence of paper on the gloss of printed matter.
