Hand-made impositions are still often taken for a considerable part of the printing industry in China. If the imposition workers do not pay attention to small details when they make a layout, they will have more or less influence on product quality and economic efficiency.
1. In the hot season, the imposition workers should have their hands sweated when they have sweat (we can wash them with sweat regardless of the number of times). Because of the sweat in the hands, you will get a film or sulfate paper. Sweat fingerprints will appear on the film or sulfuric acid paper. It is also easy to get dirty (especially if you take a film with fine color products).
2. It is best to use new adhesive tape or clean adhesive tape when making the imposition. There are many varieties of adhesive tape on the market today. Be sure to choose thinner, better-tape tapes when purchasing.
3. When working on sulfuric acid paper, be sure to pay special attention to weather changes. Because on the rainy day or when the humidity in the air is high, the swelling and shrinkage of the sulfuric acid paper is particularly large, which is disadvantageous to overprinting (except air conditioning).
4. The imposition worker must carefully and carefully draw the desk paper. First, choose a material with small stretchability to make a table paper, and pay attention to its accuracy when drawing, because the low accuracy of the paper will have a bad influence on the product quality.
5. If you use red tape to do the color mark, back ridge mark, have a certain distance from the position of the graphic and text. In addition, the size of the back ridge is also very important, it is best not to exceed 2mm.
