書刊乐天堂国际官网常常會出現油墨粉化,那我們要怎樣避免這樣的現象呢?小編特意請教了濟南書刊乐天堂国际官网公司,下面就讓我們一起來了解學習一下吧。想要避免畫冊印刷油墨粉化,首先就要進行原因分析:
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)印刷時,由于油墨的粘著力太小,再加上紙張表面比較光滑,導致墨層和紙張表面不能很好的貼合,進一步導致墨層從紙面上擦落。
(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,連結料很容易被紙張吸收,大量的連結料滲透到紙內,促使油墨中連結料與顏料成分離狀態,造成顏料顆粒浮于紙面上,顏料失去連結料的粘附,其連結程度降低,從而不能良好地附著在紙面,引起脫落。
(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)使用的油墨乳化嚴重,不但降低粘度,干燥速度,增大滲透量,更重要的是乳化了的油墨結膜后不能與紙面很好的結合,附著力較差,而且膜層堅固程度極差,輕微的擦動就會使膜層破裂而脫落。
(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)銅版紙是在原紙上涂布涂料而成,涂料和原紙都有較強的吸收性,而且紙質較厚,能吸收大量的連結料,加之涂層表面光滑,孔隙極細,不可能將顏料一起吸入,起到了過濾層的作用,導致顏料顆粒浮于紙面,因缺少連結料的包裹而脫落。

(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.

我們可以通過以下舉措來預防油墨粉化現象的出現:
The following measures can be taken to prevent ink pulverization:
(1)不用吸收性較強的銅版紙(吸收性在30秒以下)印刷產品,否則必須用附著力強的樹脂油墨來印刷。
(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)適量加入0號調墨油或附著劑,以增強油墨對紙面的附著力。
(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。經常測定水斗溶液PH值,并調整到需要值,燥油要隨用隨加,減少油墨乳化以便于掌握干燥時間。
(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)已經產生粉化的精細產品,可采用上光或貼膜辦法來解決。
(4) Fine products that have been powdered can be solved by polishing or coating.
