柔版印刷油墨都有哪些特點?印刷塑料薄膜時一般選擇哪種柔印油墨?想必大家對這些問題都很好奇,下面濟南書刊乐天堂国际官网廠家就在本文逐一解答,希望大家可以認真閱讀,對大家有所幫助!
What are the characteristics of flexographic printing ink? Which flexographic ink do you usually choose when printing plastic film? Presumably you are curious about these questions, the following Jinan publications and magazines printing manufacturers answer one by one in this article, I hope you can read carefully, to help you all!
由于柔印油墨的應用范圍及其普遍,承印資料多種多樣,所運用的柔性版油墨應與之相匹配,但就柔性版油墨的主要組成而言,它們都是由著色劑、樹脂、溶劑和助劑等組成的。多數是以揮發性枯燥為主的液體油墨,但也有少數以氧化結膜、浸透枯燥等方式的枯燥油墨。
Flexographic inks should be matched with flexographic inks due to their wide range of applications and various printing materials. However, as far as the main components of flexographic inks are concerned, they are composed of colorants, resins, solvents and auxiliaries. Most of them are liquid inks which are mainly volatile and dry, but there are also a few dry inks which are oxidized conjunctiva and immersed in dry way.
柔性版印刷油墨具有兩個顯著的特性:
Flexographic printing ink has two distinct characteristics:
低粘度與快速枯燥,正是由于低粘度,柔印機才干采用簡單的網紋傳墨輥輸墨系統,使傳墨性良好。由于柔印油墨的快干性,枯燥疾速,相鄰兩色也可完成干疊印,不只可防止枯燥不良惹起的疊印毛病,還可到達較高的印刷速度,并使柔印工藝合適于非吸收性資料的印刷。
Low viscosity and fast dryness, it is precisely because of low viscosity, flexo printing machine can use a simple mesh ink transfer roller inking system, so that good ink transfer. Because of the fast drying and dryness of flexographic ink, two adjacent colors can also complete dry overlapping, which can not only prevent the overlapping defects caused by dullness, but also achieve a higher printing speed, and make flexographic process suitable for printing non-absorptive materials.
柔印油墨的分類
Classification of Flexographic Inks
1、水基型油墨(主要用于紙張的印刷)
1. Water-based ink (mainly used for paper printing)
水基型油墨的更大特性是采用水溶性或水分散性樹脂作為連結料,明顯的減少了有機揮發物的排放,與溶劑型油墨相比擬,它能夠完整消弭某些有毒的物質對人體的危害和對包裝商品的污染。
The greatest characteristic of water-based ink is the use of water-soluble or water-dispersible resin as binder, which significantly reduces the emission of organic volatiles. Compared with solvent-based ink, it can completely eliminate the harm of some toxic substances to human body and the pollution of packaging commodities.

水基油墨使得對環保的投入少,不需求設置防火安裝、溶劑回收、無污染排入安裝。水基油墨運用中黏度穩定,不需黏度控制設備。印刷機的清洗便當且費用低,著色力強。水基油墨的缺陷是不適合薄膜印刷,枯燥速度慢,光澤度較差,耐水性較差,影響紙的伸縮性以及對印刷機有腐蝕等。

Water-based ink makes less investment in environmental protection and does not require installation of fire protection, solvent recovery and pollution-free discharge. The viscosity of water-based ink is stable in operation, and no viscosity control equipment is needed. Printer cleaning is convenient, low cost and strong dyeing power. The defects of water-based ink are not suitable for film printing, slow drying speed, poor gloss, poor water resistance, paper flexibility and corrosion to the printing press.
2、溶劑型(包括醇溶性)油墨(主要用于塑料印刷)
2. Solvent-based (including alcohol-soluble) inks (mainly for plastic printing)
溶劑型油墨是各種印刷方式普遍采用的一種油墨,有顏色鮮艷、枯燥速度快、光澤度好等特性。
Solvent-based ink is a kind of ink widely used in various printing methods. It has the characteristics of bright color, fast dryness and good gloss.
近年來,在塑料薄膜的包裝印刷中,柔性版印刷油墨正在鼎力推行應用醇溶性油墨,由于醇溶劑是有機溶劑中毒性更小的一類,而且對柔性版沒有溶蝕和損傷。良好的醇溶性油墨具有活動性好、枯燥速度快、附著結實、光澤度強、顏色鮮艷等熱點。當然醇類溶劑對環境和平安有一定的危害性。
In recent years, in packaging and printing of plastic film, flexographic printing ink is vigorously promoting the application of alcohol-soluble ink, because alcohol solvents are the least toxic organic solvents, and there is no corrosion and damage to flexographic. Good alcohol-soluble ink has good activity, fast drying speed, strong adhesion, strong gloss, bright color and other hot spots. Of course, alcohols are harmful to the environment and peace.
3、柔性版UV油墨(通用型,紙張和塑料薄膜都可印刷)
3. Flexographic UV ink (universal, paper and plastic film can be printed)
UV油墨是應用一定波長的紫外線輻射,經過光化學反響,使液態的UV油墨變成固態油墨,UV油墨的特性為:平安牢靠,無溶劑排放,不易燃,不污染環境,適用于食品、飲料、煙酒、藥品等衛生條件請求高的包裝印刷品。柔印UV油墨在國外儀器包裝范疇以應用多年,沒有呈現任何問題。
Ultraviolet ink is a kind of solid ink which is made of liquid UV ink by photochemistry reaction. The characteristics of UV ink are: safe and reliable, solvent-free, non-flammable, non-polluting environment. It is suitable for packaging and printing products with high hygienic requirements such as food, beverage, tobacco, alcohol, medicine and so on. Flexographic UV ink has been used in the field of instrument packaging abroad for many years without any problems.
