Each element of the printing surface, on the one hand, requires accurate positioning on the product after cutting and folding, on the other hand, requires that each color separation of the printing must be accurately aligned with the color separation of the previous printing. Correct positioning and accurate overprinting are the most basic requirements of printing. In the process of offset printing production, a multicolor print from the output negative, plate printing to printing, due to the complex process, the application of more materials and equipment, there are many factors affecting the overprint accuracy, it is impossible to really achieve the ideal overprint accuracy, the so-called overprint accuracy, only the overprint error does not exceed the specified range. Even within the permissible margin of error, overprinting accuracy has an important impact on the clarity and cleanliness of color printing. Therefore, we should find out the factors affecting the overprint accuracy and control them in the process practice, so that the overprint error can be controlled in the minimum range.
