使用树脂版要得到高品质的印刷品必须要有优秀的设计稿和高品质的菲林片。好的设计稿是高品质印刷品的根本,以确保好的再现性,设计时应注意:
To get high-quality printed matter, we must have excellent design draft and high-quality film. Good design draft is the basis of high quality printed matter, so as to ensure good reproducibility.
1.如果采用照相制版,所制作的墨稿中所有的线条、文字要墨度一致,否则会导致不必要的照相修正和手工修饰才能制出满意的菲林片。
1. if the photographic plate is used, all the lines and words in the produced ink will be the same. Otherwise, it will lead to the unnecessary photographic correction and manual modification to make the satisfactory film.
2.在满足客户要求的情况下,尽量使阳字笔划变细,阴字笔划变粗,这样就加大了笔划之间间隔,不容易造成印刷糊版。
2. to meet the requirements of the customer, as far as possible to make the pen stroke thinner, Yin character strokes thickening, thus increasing the interval between strokes, not easy to create a printing paste.
3.尽可能避免网点和大面积色块图案在同一块版上印刷,如果大面积色块图案和细线条图案分开单独版印刷,压力调整和颜色控制要简单得多。
3. as far as possible to avoid printing on the same block on the same block, if the large area color block pattern and the fine line pattern are printed separately, the pressure adjustment and color control are much simpler.
4.如果在一种颜色内部套印另外颜色,并且颜色之间要求不留空隙,设计时就要考虑印刷机的精度,使两种颜色的版面进行叠加印刷,叠加部分的宽度为印刷机的印刷偏差。
4. if there is another color inside one color, and no gap is required between the colors, the precision of the printer should be considered when the design is designed, and the print of the two colors will be overprinted. The width of the superposition is the printing deviation of the printer.
5.设计稿必须考虑树脂版的延伸率。制版时,版不会发生收缩和伸长,而当版装到印版辊上时,在绕版辊的方向版会延伸,而树脂版延伸率是可以计算的:树脂版延伸率=版辊+双面胶带和衬垫厚度÷(版辊+双面胶带厚度+树脂版版厚)×10%
5. the design draft must consider the elongation of the resin plate. When the plate is made, the plate does not shrink and elongate, and when the plate is mounted on the plate roll, it extends in the direction plate of the roll, and the elongation of the resin plate is computable: the elongation of the resin plate = version roll + double side tape and the thickness of the liner (the plate and the thickness of the double side tape + resin plate thickness) * 10%
