Food packaging bag suction mouth bag design small text should pay attention to the problem
1. When the general electrogravure plate making process can not achieve clear effect for small characters below 4PT, it should be changed to be above 4PT to prevent the male characters from becoming thicker, the Yin space becoming thinner or paste dead. The width of independent thin lines should not be too thin, generally larger than 0.2mm. If laser engraving is used, clear small characters about 2pt can be made, which can be used for some special anti-counterfeiting marks and other products.
2. If there are small anti white characters on the surface color of some live parts, it is necessary to communicate with customers to explain that the depth of the field and the design of anti white small characters in the Gravure Engraving of food packaging bags can not be achieved at the same time. If the field density is ensured, the anti white small characters must not be smooth and look not clear enough. On the contrary, the small text is clear, often can not guarantee enough field depth.
3. The overprint accuracy of gravure printing can only reach 0.2mm. Therefore, the characters and graphics (especially the characters) with strokes less than 0.4mm can not be printed by multi-color superimposition, and can only be printed with single ink, otherwise it is easy to cause double image.
4. Single color hollowing out should be used for small text and pattern hollow printing, multi-color superimposed hollow printing should not be used for food packaging bags, and the background color of photos should not be used for direct hollow printing. For small words and patterns, it is not suitable to use text pattern hollow out overprint. http://www.dgbpk.com/
