有印刷人員反映在印刷東西期間出現(xiàn)某些問題是難免的,比如說飛墨現(xiàn)象的出現(xiàn)便是常有的問題,那么要想解決問題就需要來找到原因。
Some printers reflect that it is inevitable to have some problems during printing, such as the phenomenon of flying ink is a common problem, so in order to solve the problem, we need to find the cause.
印刷時,空氣的相對濕度低,促進(jìn)了飛墨的產(chǎn)生。當(dāng)濕度增加時,電荷減少,飛墨量變小。如果油墨中潤版液過多,粘度會急劇下降,墨絲變短,會造成嚴(yán)重的飛墨現(xiàn)象。排斥油墨,造成金屬墨輥脫墨。
When printing, the relative humidity of the air is low, which promotes the generation of flying ink. When the humidity increases, the charge decreases and the amount of flying ink becomes smaller. If the ink version of the solution is too much, the viscosity will drop sharply, the ink becomes short, will cause serious flying ink phenomenon. Repulsive ink, resulting in metal roller deinking.
墨輥上的墨層越厚,飛墨越大。當(dāng)紙張性能對油墨附著力不好時,很容易造成墨輥積墨,造成飛墨現(xiàn)象。高分子量油墨的粘合劑在油墨分裂時容易拉長絲,造成飛墨。此外,當(dāng)墨輥表面凹凸不平,表面干燥開裂時,部分墨層變厚,墨霧量增加,這也是造成飛墨現(xiàn)象的因素之一。如果速度太快,導(dǎo)致墨水飛濺的概率會更高。
The thicker the ink layer on the roller, the bigger the flying ink. When the paper performance of ink adhesion is not good, it is easy to cause ink roller accumulation, resulting in flying ink phenomenon. High molecular weight ink adhesive in ink splitting easy to elongate wire, resulting in flying ink. In addition, when the surface of the ink roller is uneven, the surface is dry and cracked, part of the ink layer thickens, the amount of ink mist increases, which is also one of the factors causing the phenomenon of flying ink. If the speed is too fast, the chances of ink splattering are higher.
濟(jì)南印刷人員在此提醒大家,如果油墨的粘度太大,油墨會在墨輥出口處被拉伸,容易產(chǎn)生飛墨,同時也會造成油墨轉(zhuǎn)移不均勻,使紙張拉毛和粉化,紙張將難以從毯子上剝離,容易壓花和掉落。如果粘度太小,墨層分裂不好,容易產(chǎn)生飛墨。同時容易乳化油墨、糊版、擴(kuò)大網(wǎng)點(diǎn),影響印品質(zhì)量。
Ji 'nan printers here to remind you that if the viscosity of the ink is too large, the ink will be stretched at the exit of the ink roll, easy to produce flying ink, but also cause uneven ink transfer, so that the paper wool and powder, paper will be difficult to peel from the blanket, easy to embossing and falling. If the viscosity is too small, ink layer splitting is not good, easy to produce flying ink. At the same time easy emulsion ink, paste version, expand dot, affect the quality of printing.
為什么印刷時會出現(xiàn)飛墨現(xiàn)象?以上便是問題的出現(xiàn)原因了,如果想順利的完成印刷過程并有好的質(zhì)量,那就注意預(yù)防。更多內(nèi)容就來網(wǎng)站buiy.cn咨詢吧。
