涂布纸和不涂布纸张给画册印刷带来的品质

涂布印刷纸是在原纸上涂上一层涂料,以颜料、胶黏剂、增黏剂、荧光剂、润滑剂等辅佐溶剂为主要成分的涂布液,干燥后再进行平滑处理,使纸张具有良好的光学性质及印刷适性等。主要用于印刷杂志、书本、商标、包装、商品目录等,是目前文化出版、广告设计、印刷装订及工商业界常使用纸种之一。由于涂布纸表面平滑、白度好,一般用于五颜六色印刷。涂布纸原纸一般多用道林纸,也有使用含磨木浆或脱墨浆原纸的涂布纸。

Coated printing paper is a coating liquid which is mainly composed of auxiliary solvents such as pigments, adhesives, tackifiers, fluorescent agents and lubricants. After drying, it is smoothed to make the paper have good optical properties and printing adaptability. Mainly used for printing magazines, books, trademarks, packaging, catalogues, etc., is currently one of the most commonly used paper types in cultural publishing, advertising design, printing and binding, and industrial and commercial circles. Because of its smooth surface and good whiteness, coated paper is generally used for multicolour printing. Coated paper base paper is generally multi-purpose woodland paper, but also coated paper containing ground wood pulp or deinked pulp base paper.

涂布纸是用涂布量的多少加以分类的。根据涂布量由多到少依次分为铜版纸、涂布纸、轻量涂布纸、微涂布印刷用纸。

Coated paper is classified by the amount of coating. According to the amount of coating, it can be divided into copper plate paper, coated paper, lightweight coated paper and micro-coated printing paper.

许多功能性质构成纸张的基本成分是植物纤维,这一特色决定了纸的许多性质,这儿称之为功能性质:纤维素是白色的,因而纸是白色的,除非含有木素杂质或是添加了染料以给予它色彩;纤维素很容易吸水,因而纸也吸水,印刷纸不得不进行特别处理来减小吸水能力以防止洇水;纤维素是吸潮的,因而纸是吸潮的,它会跟着相对湿度的改变而吸人空气中的水分或放出水分;非涂布印刷纸具有多相杂乱的结构要素成分在纸的成分中既有较长的,也有较短的不同来历的纤维,还有填料、胶料、染料和各种添加剂。由于纤维质料的品种和加工办法不同,它们的构造和性质也各不相同。填料、胶料等也因品种不同而有功能差异。

Many functional properties constitute the basic component of paper, which determines many properties of paper. Here we call it functional properties: cellulose is white, so paper is white, unless it contains lignin impurities or dyes to give it color; cellulose is easy to absorb water, so paper also absorbs water, printing. Brushing paper has to be specially treated to reduce its water absorption capacity to prevent soaking; cellulose absorbs moisture, so paper absorbs moisture, and it absorbs or releases moisture in the air with the change of relative humidity; non-coated printing paper has many disordered structural elements, which are both longer and shorter in the composition of paper. Fibers of different origins include fillers, adhesives, dyes and various additives. Due to the different varieties and processing methods of fiber materials, their structures and properties are also different. Fillers and rubber also have different functions because of different varieties.

非涂布的纸张在印刷的时分跟涂布纸是有差异的,就拿小编前次一次的阅历来说,客户在印刷台历,需求用到艺术纸,在数码打样的时分小编用的是涂布的纸张,在正式印刷的时分在细节上我忘记了,数码打样的色彩胜过传统印刷了,等上机印刷的时分色彩突然就很昏暗,终究的原因在纸张上,还好其时客户的数量和尺寸不是很大,当即印刷上就发现了,立马就停机了,才没形成很大的丢失,小编也算是吃一见长一智。数码印刷的墨路只是在表面上,所以色彩很鲜亮。

Non-coated paper is different from coated paper in printing time. Take the previous experience of small edition as an example, customers need to use art paper in printing desk calendar, while small edition is coated paper in digital proofing. In formal printing, I forget in detail that the color of digital proofing is better than the tradition. Printed, wait for the time of printing suddenly very dark color, the ultimate reason is in the paper, but at that time the number and size of customers is not very large, immediately found on the printing, immediately stopped, did not form a great loss, Xiaobian is also a long-term wisdom. Digital printing ink is only on the surface, so the color is very bright.

非涂布印刷纸的大多数结构都有双面性,即纸幅的双面性质不同这种双面性不只决定于上面已经指出的结构要素分布的各向异性,而且也决定于纸的双面状态不同。

Most structures of non-coated printing paper have two-sidedness, that is, the difference of the two-sidedness of the sheet depends not only on the anisotropy of the distribution of the structural elements mentioned above, but also on the difference of the two-sidedness of the paper.
