印刷时出现干燥效果的五个影响因素

来源:http://www.xinfengyinshua.cn/   发布时间:2022-06-06
在日常的印刷工作中,印刷厂家常常会对印刷产品质量进行检查,不免会发现有问题出现,比如印刷时出现干燥效果,那么影响因素是怎样的呢?
In the daily printing work, printing manufacturers often check the quality of printing products, and inevitably find problems, such as the drying effect during printing. What are the influencing factors?
印刷机排气系统对干燥的影响
Influence of exhaust system of printing press on drying
如果印刷机的排气系统不能保持畅通,印刷时会造成挥发的溶剂不能及时清除。如果烘箱中的溶剂过高,也会阻碍溶剂更快挥发,影响印品的干燥程度。
If the exhaust system of the printing machine cannot be kept unblocked, the volatile solvent will not be removed in time during printing. If the solvent in the oven is too high, it will also prevent the solvent from volatilizing faster and affect the dryness of the printed matter.
油墨对干燥效果的影响

(1)溶剂型油墨中混合溶剂对挥发速度的影响直接决定了油墨的干燥性能,不同组合在混合溶剂中的挥发速度也会不同。一些混合溶剂产生的不同溶剂和不同比例的溶剂,很容易改变油墨的溶剂挥发速度,从而提高干燥性能。
(1) The influence of mixed solvents on the volatilization rate in solvent based inks directly determines the drying performance of inks, and the volatilization rate of different combinations in mixed solvents will be different. Some mixed solvents produce different solvents and different proportions of solvents, which can easily change the solvent evaporation rate of the ink, so as to improve the drying performance.
(2)水性油墨的干燥效果主要与PH值有关。同等条件下,PH值越低,油墨的干燥速度越快。相反,油墨的干燥速度会比较慢。一旦油墨干燥速度慢,很容易造成印品背面脏污现象。
(2) The drying effect of water-based ink is mainly related to pH value. Under the same conditions, the lower the pH value, the faster the drying speed of the ink. On the contrary, the drying speed of ink will be slow. Once the ink drying speed is slow, it is easy to cause dirt on the back of the printed matter.

印刷速度对干燥效果的影响

不同的印刷速度对干燥性能有不同的要求。速度要求还是比较高的,对烘箱的加热距离和干燥效率有比较高的要求。
Different printing speeds have different requirements for drying performance. The speed requirements are relatively high, and there are relatively high requirements for the heating distance and drying efficiency of the oven.
印版对干燥的影响

济南印刷包装厂家认为对于凹版印刷,印版单元的深度对干燥速度有很大影响。例如深度为33μm的网孔和深度为18μm的网孔,前者印刷油墨的干燥时间是后者的1倍以上。
Jinan printing and packaging manufacturers believe that for gravure printing, the depth of the printing plate unit has a great impact on the drying speed. For example, the depth is 33 μ M mesh and depth of 18 μ M mesh, the drying time of the former printing ink is more than twice that of the latter.
环境条件的影响
Impact of environmental conditions
一般在20℃以下的温度环境下印刷,油墨的自然干燥减弱。在30°C以上的环境中打印时,墨水的自然干燥趋于加速。空气湿度高对干燥的影响:一是空气中的水分进入油墨,导致溶剂的综合挥发性变差;其次,空气中大量水分的存在会抑制溶剂的挥发。
Generally, when printing at a temperature below 20 ℃, the natural drying of the ink is weakened. When printing in an environment above 30 ° C, the natural drying of ink tends to accelerate. The influence of high air humidity on drying: first, the moisture in the air enters the ink, resulting in poor comprehensive volatility of the solvent; Secondly, the presence of a large amount of moisture in the air will inhibit the volatilization of the solvent.
