  通明油墨的挑选和运用
Selection and application of transparent ink
通明油墨的挑选运用要依据不同的承印物特色客户的要求等进行,归纳起来,首要从以下3个方面来考虑,合理挑选通明油墨。
The selection and application of clear ink should be based on the requirements of customers with different characteristics of the printed material. To sum up, the following three aspects should be considered first, and the clear ink should be selected reasonably.
1.依据承印资料选用与之习惯的油墨:如印刷表印镀铝膜时有必要挑选表印通明油墨:印刷BOPP薄膜又要复合镀铝时则应选用里印通明(复合)油墨。所以,能够这样说承印资料的种类决议了运用的油墨类型即使是同一种类的薄膜资料,也往往因种类和等级的不同而有所差异。别的留意,选用通明油墨印刷时一般在该色案下面不必白色垫底,因为白色起消光作用会大大下降其运用作用和价值。相对来讲,通明油墨印刷的色案处比有白色油墨垫底的地方薄O.Olmm。
1. Choose the ink that is used to it according to the printing material: If it is necessary to select the clear ink when printing aluminized film, it is necessary to use the clear ink when printing BOPP film and composite aluminizing ink when printing BOPP film. Therefore, it can be said that the type of printed material determines the use of ink types, even if the same kind of film materials, also often varies according to the type and grade. Otherwise, when using clear ink to print, it is not necessary to use white as the bottom of the color case, because white will greatly reduce its use and value. Relatively speaking, the case of brightly printed ink is O.Olmm thinner than that with white ink.
2.依据客户供给的样品挑选习惯的通明油墨:通明油墨的挑选包含色相和色泽.若要分配专色通明油墨时,有必要咨询出产供货商因为通明油墨专色的分配不同于一般专色油墨,其难度显着高于不通明油墨专色分配。

2. According to the customer's sample selection habits bright ink: clear ink selection contains color and color. To distribute spot color bright ink, it is necessary to consult the manufacturer because the distribution of spot color bright ink is different from the general spot color ink, the difficulty is significantly higher than that of opaque ink spot color distribution.

3.依据包装的实际情况和用处挑选相应的通明油墨:如包装印刷品耐高温、耐晒、耐透渗等参数,这些都有必要列入挑选的考虑领域。此外,通明油墨印刷要想取得高亮度和艳丽的色彩离不开镀铝膜或铝箔纸、铝箔等资料因为通明油墨的通明性极高与镀铝膜复合或直接印刷到上述资料上会发作改变以透出金属的光泽与色彩.使黄更黄、绿更绿、红更红作用更佳。
3. According to the actual situation and use of the packaging to select the appropriate clear ink: such as packaging printing high temperature resistance, sunlight resistance, permeability and other parameters, these are necessary to be included in the selection of areas of consideration. In addition, bright ink printing can not get high brightness and gorgeous color without aluminum film or aluminum foil paper, aluminum foil and other information because of the high brightness of bright ink and aluminum film composite or directly printed to the above information will be changed to penetrate the luster and color of the metal, so that yellow, green, red and green role better. .
通明油墨印刷中常见毛病的扫除
Elimination of common faults in ink printing
通明油墨在软包装印刷运用过程中,多用镀铝膜或铝箔垫底以进步印刷和视觉作用。但在实际运用过程中常常发作一些质量现象比如通明油墨印刷后有麻点、铺墨不平等现象这样就大大下降了其预期作用,因而要了解通明油墨的性质及印刷特色,分析扫除。
In the process of flexible packaging printing, transparent ink usually uses aluminum film or aluminum foil to pad the bottom to improve printing and visual effect. However, in the actual application process, some quality phenomena often occur, such as numbness and inking inequality after the printing of clear ink, which greatly reduces its expected effect. Therefore, it is necessary to understand the nature of clear ink and printing characteristics, analysis and cleaning.
1.通明油墨印刷时发作“麻点”现象
1. ink printing occurs when printing.
首要原因和处理办法这种毛病表现为印刷后的产品垫上镀铝膜后,其亮光作用就出来了,但仔细调查会发现其外表有针孔状,好像是未印刷上去。发作这个毛病的首要原因是:
The primary cause and treatment of this problem is that after the printed product is coated with aluminium film, its brightening effect comes out, but careful investigation will find that the appearance of the pinhole, as if not printed. The main reason for this attack is:
①压印胶辊外表不可细腻,或有尘埃等异物,形成此处油墨不可厚。应查看压印胶辊是否粘有脏物,并将其外表擦洗洁净;查看胶辊质量.替换合格的胶辊。
(1) the appearance of imprint cots can not be delicate or dust and other foreign matter. Ink can not be thickened here. Check whether the embossing cots are sticky with dirt and scrub them clean. Check the quality of the cots. Replace the qualified cots.
②薄膜中所含的增塑剂、光滑剂等浮到外表上阻碍了油墨的正常搬运和光滑。印刷前要将塑料薄膜预热等印前处理,实施薄膜加温印刷若还不可则应替换适宜的塑料薄膜。
(2) The plasticizer and smoother contained in the film float to the surface and hinder the normal transportation and smoothness of the ink. The plastic film should be preheated before printing, and the suitable plastic film should be replaced if the film heating printing can not be carried out.
③油墨钻度太高、枯燥过快或钻著剂缺少形成油墨搬运、湿润习惯性不良。应适当下降油墨钻度而且用缓千溶剂。
3. Ink drills are too high, drunks too fast or lack of drilling agents to form ink handling and poor wetting habits. Ink drills should be appropriately lowered and slow solvent should be used.
④印刷压力太小。可适当加大印刷压力并注惫操控好印刷压力(一般在4kg左右)。
(4) printing pressure is too small. Printing pressure can be increased appropriately, and printing pressure can be controlled (usually around 4kg).
⑤印版或压印胶辊的问题(表现为麻点比较有规则)应仔细查看印版及压印胶辊是否有缺点若有则应从头制版或替换好的胶辊。
_printing plate or offset roll problems (for pitting is more regular) should be carefully checked whether the plate and offset roll has any shortcomings, if any, should be made from scratch or replace the good roll.
2.印刷通明油墨后发作粘连现象
2. adhesion after printing.
首要原因和处理办法:在高温、高湿的梅雨季节塑料膜通过凹版印刷后收卷放皿期间易发作粘连现象,通明油墨被成块粘下来,在油墨处甚至不能与基层塑料膜分开,致使形成许多废品。印品发作粘连大多是由油墨发钻、环境湿度太高、压力太大等形成的。
Primary reason and treatment: plastic film in high temperature, high humidity Meiyu season through gravure printing during the roll-up and dish-release easy to occur adhesion, clear ink is sticky in pieces, in the ink can not even be separated from the basic plastic film, resulting in a lot of waste products. Most of the printed products are caused by ink drills, environmental humidity and pressure.
3.印刷通明油墨镀铝复合后光泽度不高
3. printing bright ink, aluminum plating compound after gloss is not high.
首要原因和处理办法:发作这种现象的首要原因是:①油墨自身的通明性差应替换通明性好的油墨。
The first reason and treatment: the first reason for this phenomenon is: 1. Ink itself poor brightness should replace good brightness of the ink.
②印刷时溶剂蒸腾太快钻度太低,应依据孺要选用适宜的慢干溶剂,查看并进步油墨钻度。③镀铝层均性不良,形成反光泽差要替换镀铝膜并确保其外表均匀、无针孔。④刮墨刀视点太大印版网穴浅要调整操控好刮墨刀视点,一般夹角操控在35度左右为宜。
(2) When printing, solvent transpiration is too fast and the drilling degree is too low, the suitable slow-drying solvent should be selected to check and improve the ink drilling degree. (3) Bad homogeneity of the aluminized layer, forming poor reflective luster to replace the aluminized film and ensure its appearance uniform, no pinholes. (4) The view of the scraper is too big and the screen hole is too shallow. It is necessary to adjust and control the view of the scraper well. Generally, the angle of the scraper should be controlled at about 35 degrees.
4.通明油墨发作结块现象
4. lump phenomenon
首要原因和处理办法:此现象一般发作在气温较低的情况下。此种情况下,应将油墨放里在35℃室温下热化。为避免意外,还有必要由专人看守。
First and foremost reason and treatment: this phenomenon usually occurs when the temperature is low. In this case, the ink should be heated at room temperature of 35 degrees. In order to avoid accidents, it is also necessary to be watched by someone.
总归溶剂配比失调、钻度操控不妥或工艺操作失误等都极或许导致许多毛病现象所以每一个环节都不能大意。因而在运用通明油墨印刷时,要想取得抱负的作用各个环节有必要严格把关,而且要依据印刷的实际情况挑选适宜的油墨。
The total solvent mismatch, improper drilling control or process operation errors are likely to cause many problems, so each link can not be neglected. Therefore, in the use of clear ink printing, in order to achieve the desired role of each link is necessary to strictly check, and according to the actual situation of printing to select the appropriate ink.
