书刊杂志印刷出现油墨粉化的原因和预防方法!

书刊杂志印刷常常会出现油墨粉化,那我们要怎样避免这样的现象呢?小编特意请教了济南书刊杂志印刷公司,下面就让我们一起来了解学习一下吧。想要避免画册印刷油墨粉化,首先就要进行原因分析:
Pulverized ink often appears in the printing of books and magazines. How can we avoid this phenomenon? Xiao Editor specially consulted Jinan Book and Magazine Printing Company, let's learn about it together. In order to avoid the powdering of printing ink in picture albums, the reasons should be analyzed first.
(1)印刷时,由于油墨的粘着力太小,再加上纸张表面比较光滑,导致墨层和纸张表面不能很好的贴合,进一步导致墨层从纸面上擦落。
(1) When printing, because the adhesion of ink is too small and the surface of paper is relatively smooth, the ink layer and the surface of paper can not fit well, further leading to the ink layer from the paper surface scratch.
(2)由于油墨太稀薄,连结料很容易被纸张吸收,大量的连结料渗透到纸内,促使油墨中连结料与颜料成分离状态,造成颜料颗粒浮于纸面上,颜料失去连结料的粘附,其连结程度降低,从而不能良好地附着在纸面,引起脱落。
(2) Because the ink is too thin, the binder is easily absorbed by the paper, and a large number of binders penetrate into the paper, which makes the binder and pigment components separate from each other, resulting in the floatation of the pigment particles on the paper surface, the loss of the binder adhesion of the pigments, and the reduction of the degree of the binder, which can not be well adhered to the paper surface, resulting in peeling.
(3)使用的油墨乳化严重,不但降低粘度,干燥速度,增大渗透量,更重要的是乳化了的油墨结膜后不能与纸面很好的结合,附着力较差,而且膜层坚固程度极差,轻微的擦动就会使膜层破裂而脱落。
(3) The use of ink emulsification is serious, not only reduces the viscosity, drying speed, increase the permeability, more importantly, the emulsified ink conjunctiva can not be well combined with the paper surface, adhesion is poor, and the film is very weak, slight rubbing will make the film break and fall off.
(4)铜版纸是在原纸上涂布涂料而成,涂料和原纸都有较强的吸收性,而且纸质较厚,能吸收大量的连结料,加之涂层表面光滑,孔隙极细,不可能将颜料一起吸入,起到了过滤层的作用,导致颜料颗粒浮于纸面,因缺少连结料的包裹而脱落。

(4) Copper plate paper is coated with paint on the base paper. The coatings and the base paper have strong absorptivity, and the paper is thicker, which can absorb a large number of binders. In addition, the coating surface is smooth and the pore is very fine. It is impossible to inhale the pigments together, which acts as a filter layer, resulting in the floating of the pigments particles on the paper surface due to the lack of binders. The package fell off.

我们可以通过以下举措来预防油墨粉化现象的出现:
The following measures can be taken to prevent ink pulverization:
(1)不用吸收性较强的铜版纸(吸收性在30秒以下)印刷产品,否则必须用附着力强的树脂油墨来印刷。
(1) No copperplate paper (less than 30 seconds absorbability) with strong absorbability is used to print products, otherwise, it must be printed with resin ink with strong adhesion.
(2)适量加入0号调墨油或附着剂,以增强油墨对纸面的附着力。
(2) Proper addition of No. 0 toner or adhesives to enhance the adhesion of ink to paper surface.
(3)控制油墨的乳化,版面用水量要小。经常测定水斗溶液PH值,并调整到需要值,燥油要随用随加,减少油墨乳化以便于掌握干燥时间。
(3) To control the emulsification of ink, the amount of water needed for the layout should be small. Often determine the PH value of bucket solution and adjust it to the required value. Dry oil should be added as needed to reduce ink emulsification in order to grasp the drying time.
(4)已经产生粉化的精细产品,可采用上光或贴膜办法来解决。
(4) Fine products that have been powdered can be solved by polishing or coating.
