濟南標簽印刷:哪三個因素影響印刷紙張的顏色

來源:http://www.seven2000.com   日期:2019-09-04

  1. 吸墨性。相同的油墨在相同的印刷條件下吸收不同的紙張,會產生不同的印刷光澤。印刷紙的結構決定了紙張表面有由植物纖維形成的凹凸孔洞。濟南印刷廠在印刷時,為了使紙張表面獲得良好的均勻性和平滑性,一般都會在印刷表面涂抹不同厚度的顏料。吸收率不同,必然使油墨層的顏色不同。

  1. Ink absorption. The same ink absorbs different paper under the same printing conditions and produces different printing gloss. The structure of printing paper determines that there are concave and convex holes formed by plant fibers on the surface of paper. In Jinan Printing Plant, in order to achieve good uniformity and smoothness of the paper surface, the printing surface is usually coated with different thickness of pigments. Different absorptivity will inevitably make the color of the ink layer different.

  2. Jinan Label Printing: Which three factors affect the color of printed paper 2. Gloss and smoothness. Printing glossiness depends on the glossiness and smoothness of paper. The surface of printing paper belongs to semi-glossy surface, especially coated paper.
  3、紙張白度。紙張的白度、油墨層的顏色都會有或多或少的影響。對于相同的白板,白度不一樣,油墨層的色差主要體現在專色油墨的黑色組成上,尤其是對于70多種顏色的亮度,影響尤為明顯,導致專色油墨的比例差別很大。因此,在實際生產中也應選用同樣白度的紙張印刷,以減少紙張印刷顏色的白度。
  3. Paper whiteness. The whiteness of paper and the color of ink layer will have more or less influence. For the same white board, whiteness is different, the color difference of the ink layer is mainly reflected in the black composition of spot ink, especially for the brightness of more than 70 colors, the influence is particularly obvious, resulting in the different proportion of spot ink. Therefore, in order to reduce the whiteness of paper printing color, paper printing with the same whiteness should also be selected in actual production.
