1, the watermarked works are printed on the watermark by Fang Jie. Watermark refers to the traditional method of engraving and painting with wood in China. Water is used to blend pigments instead of oil, which is different from the general color printing method, so it is called watermark. Also known as watermark woodcut, paper money, certificates, securities, food stamps, etc. It is usually watermarked to prevent counterfeiting. For example, in the left margin of the 20 15 version of 100 RMB, you can see the head image through the light, which is the watermark.
2. A movie is a movie, an old translation of a movie. Now it generally refers to film, and it can also refer to negative film in printing and plate making. In order to ensure the readability of the bar code, it is suggested to print out the black and white draft first, scan and verify it with the bar code machine, and then make the film after it is qualified. What needs to be emphasized here is that. The size of the bar code should refer to the standard. Generally speaking, it can be enlarged appropriately within the range of no more than 2 times, so as to reduce the difficulty of plate making and printing and ensure the printing quality. The direction of the bar code should be consistent with the printing direction of the carton, so as to print a good quality bar code.
