不同纸张印刷适度也不同!

不同纸质的印刷适性截然不同,包装盒印刷专家朗程介绍到如果没有“因材制宜”采取相应的工艺措施,就会给正常的生产带来些许问题。但即使采用同一类型纸品,由于不同品牌或不同厂家在造纸用料及工艺上的差异,也会使原纸的质量、印刷适性存在一定的差异。如有的白纸板、白卡纸、玻璃卡属于偏酸性,印刷之后墨色干燥较为缓慢,会导致半成品套印困难,不合格品率明显增加;有的低档白纸板、玻璃卡表面强度差,印刷过程中容易出现掉粉、掉毛、起泡或脱层等质量故障现象。

The printability of different paper is quite different. Langcheng, an expert in packing box printing, introduced that some problems would be brought to normal production if the corresponding technological measures were not taken according to the material conditions. However, even if the same type of paper products are used, the quality and printability of base paper will be different due to the differences of materials and processes between different brands or manufacturers. For example, some white paperboard, white cardboard and glass card are slightly acidic, and the ink drying is slow after printing, which will lead to difficulties in semi-finished overprinting and increase the rate of unqualified products; some low-grade white paperboard and glass card have poor surface strength, which is easy to cause quality problems such as powder dropping, hair dropping, foaming or delamination during printing.
图像的色彩分解,传递合成,早期的彩色印刷品是由九至十二块不等的印刷版叠印而成,不但费时费工,而且得到的只是接近彩色效果图片,直到十九世纪末在色彩学有关原色,间色,混色及分色成像理论上有突破性发现后,才使彩色技术发展到仅用黄、品红,青三色版即可叠印出和原稿接近的彩色印刷品,但由于印刷用的Y MC三元色墨活多或少含有杂色,其纯度并非理想的,造成在分色上及叠印过程中容易形成偏色,因此使用黑版能稳定图像暗调颜色,也解决黑色文字印刷。
Color decomposition, transmission and synthesis of images. In the early stage, color printing was made of nine to twelve printing plates, which not only took time and labor, but also got close to the color effect pictures. It was not until the breakthrough in the theory of primary color, intermediate color, color mixing and color separation and imaging in the end of the 19th century that color technology developed to use only yellow, magenta and cyan The tricolor plate can be used to produce the color printed matter close to the original. However, the purity of YMC ternary color ink is not ideal due to its high or low impurity, which makes it easy to form color deviation in color separation and overprint process. Therefore, the use of black plate can stabilize the image dark tone color and solve the problem of black text printing.

As printing paper is mostly determined by customers, printing enterprises are often in a passive state. However, even if we are faced with the unsatisfactory paper products selected by customers in order to reduce costs, we also need to carefully design the printing process to improve the quality as much as possible. After practice, the author obtains some experience and is willing to share with readers.
印刷厂不能光是有一些简单的,比如说(骑马订、折页机、覆膜机、轧车机等,)对于一些要求高些画册的要求,不光是这些简单的机器能做好的,里面还夹杂一些跨页,拉页等等就需要来研究这么做好这个装订方式,就比如说一些教辅书之类的画册,用在一些学龄前儿童的手上,他们对装订的方式比较高,小朋友对一些比较吸引人的图画,她或者他们对书本的翻的方式可能比叫夸张,容易造成掉页脱离等等一些情况的发生,这些就是要有的方式来控制怎么装订好。
The printing factory can't just have some simple ones, such as (horse riding, folding, laminating, rolling machine, etc.) for some picture books with higher requirements, it's not only these simple machines that can do it well, but also some cross pages, pull pages, etc., which need to be studied to do this binding way, such as some teaching auxiliary books and other picture books, which are used in some learning In the hands of pre-school children, their binding methods are relatively high. The children's way of turning over some attractive pictures or books may be more exaggerated than exaggeration. It is easy to cause page dropping and separation. These are the professional ways to control how to bind well.
