印刷時出現干燥效果的五個影響因素

來源:http://www.703248.com/   發布時間:2022-06-06
在日常的印刷工作中,印刷廠家常常會對印刷產品質量進行檢查,不免會發現有問題出現,比如印刷時出現干燥效果,那么影響因素是怎樣的呢?
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?
印刷機排氣系統對干燥的影響
Influence of exhaust system of printing press on drying
如果印刷機的排氣系統不能保持暢通,印刷時會造成揮發的溶劑不能及時清除。如果烘箱中的溶劑過高,也會阻礙溶劑更快揮發,影響印品的干燥程度。
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.
油墨對干燥效果的影響

(1)溶劑型油墨中混合溶劑對揮發速度的影響直接決定了油墨的干燥性能,不同組合在混合溶劑中的揮發速度也會不同。一些混合溶劑產生的不同溶劑和不同比例的溶劑,很容易改變油墨的溶劑揮發速度,從而提高干燥性能。
(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與PH值有關。同等條件下,PH值越低,油墨的干燥速度越快。相反,油墨的干燥速度會比較慢。一旦油墨干燥速度慢,很容易造成印品背面臟污現象。
(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.

印刷速度對干燥效果的影響

不同的印刷速度對干燥性能有不同的要求。速度要求還是比較高的,對烘箱的加熱距離和干燥效率有比較高的要求。
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.
印版對干燥的影響

濟南印刷包裝廠家認為對于凹版印刷,印版單元的深度對干燥速度有很大影響。例如深度為33μm的網孔和深度為18μm的網孔,前者印刷油墨的干燥時間是后者的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.
環境條件的影響
Impact of environmental conditions
一般在20℃以下的溫度環境下印刷,油墨的自然干燥減弱。在30°C以上的環境中打印時,墨水的自然干燥趨于加速??諝鉂穸雀邔Ω稍锏挠绊懀阂皇强諝庵械乃诌M入油墨,導致溶劑的綜合揮發性變差;其次,空氣中大量水分的存在會抑制溶劑的揮發。
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.
