層次印刷不勻的因素可以分為兩種:梯度層印刷不平整和淺層印刷不平整。不均勻漸變印刷的主要原因是,無論如何選擇雕刻過程在制版過程中,很難避免點容易產生平行的地區,雖然在印刷過程中通過調整生產墨水的粘度可以改變一個平行的地區,但是不能避免點。因此,在制作過程中,梯度層的印刷不均勻是難以控制的,更好在制版中選擇一種更好的雕刻工藝,以減少奇怪的印刷不均勻現象。下面濟南包裝印刷公司將幫助您分析印刷不平整的因素和方案。
There are two factors of uneven level printing: uneven gradient level printing and uneven shallow level printing. The main reason for uneven gradient printing is that it is difficult to avoid parallel areas in the engraving process. Although a parallel area can be changed by adjusting the viscosity of the production ink in the printing process, points cannot be avoided. Therefore, in the process of making, it is difficult to control the uneven printing of the gradient layer. It is better to choose a better engraving process in the plate making to reduce the strange uneven printing phenomenon. Jinan packaging printing company will help you to analyze the factors and solutions of uneven printing.
淺層打印不均勻主要是由以下原因造成的:
Uneven shallow printing is mainly caused by the following reasons:
一是印刷過程中油墨粘度過高或溶劑揮發速度過快而引起的一組刀絲狀不勻。
One is a group of knife like unevenness caused by too high viscosity of ink or too fast volatilization of solvent in the printing process.
二是油墨在印刷過程中粘度過低,導致疊印過程中印版上的印品毛質不均勻,導致印刷不均勻。
Second, the viscosity of the ink is too low in the printing process, which leads to the uneven gross quality of the printed matter on the overprint plate and the uneven printing.
三是印版滾筒粗糙,有毛刺,導致刮刀刮不凈。
Third, the plate cylinder is rough and has burrs, which causes the scraper to scratch unclearly.
因此,可以采取以下措施來淺印不勻:適當降低溶劑的蒸發率,增加慢干溶劑;適當提高印刷車間溫度,降低印刷車間溫度;選用質量較好的油墨和印版滾筒。
Therefore, the following measures can be taken to solve the uneven light printing: properly reduce the evaporation rate of the solvent, increase the slow drying solvent; properly increase the temperature of the printing workshop, reduce the temperature of the printing workshop; select the ink and plate cylinder with good quality.
