柔版印刷油墨都有哪些特点?印刷塑料薄膜时一般选择哪种柔印油墨?想必大家对这些问题都很好奇,下面济南书刊杂志印刷厂家就在本文逐一解答,希望大家可以认真阅读,对大家有所帮助!
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!
由于柔印油墨的应用范围及其普遍,承印资料多种多样,所运用的柔性版油墨应与之相匹配,但就柔性版油墨的主要组成而言,它们都是由着色剂、树脂、溶剂和助剂等组成的。多数是以挥发性枯燥为主的液体油墨,但也有少数以氧化结膜、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两个显着的特性:
Flexographic printing ink has two distinct characteristics:
低粘度与快速枯燥,正是由于低粘度,柔印机才干采用简单的网纹传墨辊输墨系统,使传墨性良好。由于柔印油墨的快干性,枯燥疾速,相邻两色也可完成干叠印,不只可防止枯燥不良惹起的叠印毛病,还可到达较高的印刷速度,并使柔印工艺合适于非吸收性资料的印刷。
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.
柔印油墨的分类
Classification of Flexographic Inks
1、水基型油墨(主要用于纸张的印刷)
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树脂作为连结料,明显的减少了有机挥发物的排放,与溶剂型油墨相比拟,它能够完整消弭某些有毒的物质对人体的危害和对包装商品的污染。
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.

水基油墨使得对环保的投入少,不需求设置防火安装、溶剂回收、无污染排入安装。水基油墨运用中黏度稳定,不需黏度控制设备。印刷机的清洗便当且费用低,着色力强。水基油墨的缺陷是不适合薄膜印刷,枯燥速度慢,光泽度较差,耐水性较差,影响纸的伸缩性以及对印刷机有腐蚀等。

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、溶剂型(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)
溶剂型油墨是各种印刷方式普遍采用的一种油墨,有颜色鲜艳、枯燥速度快、光泽度好等特性。
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.
近年来,在塑料薄膜的包装印刷中,柔性版印刷油墨正在鼎力推行应用醇溶性油墨,由于醇溶剂是有机溶剂中毒性更小的一类,而且对柔性版没有溶蚀和损伤。良好的醇溶性油墨具有活动性好、枯燥速度快、附着结实、光泽度强、颜色鲜艳等热点。当然醇类溶剂对环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,纸张和塑料薄膜都可印刷)
3. Flexographic UV ink (universal, paper and plastic film can be printed)
UV油墨是应用一定波长的紫外线辐射,经过光化学反响,使液态的UV油墨变成固态油墨,UV油墨的特性为:平安牢靠,无溶剂排放,不易燃,不污染环境,适用于食品、饮料、烟酒、药品等卫生条件请求高的包装印刷品。柔印UV油墨在国外仪器包装范畴以应用多年,没有呈现任何问题。
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.
