Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] An embodiment of the present invention provides a method for judging the color difference of tipping paper, which includes the following steps:

[0022] S1: When mixing tipping paper, first formulate a color similar to the standard sample based on experience, and then use a colorimeter to detect it. According to the colorimeter measurement, the △E and △Lab values ​​of the standard sample and the tested sample are displayed. Adjust the color scheme, supplemen...

Abstract

The present invention provides a tipping paper chromatic aberration determination method. The method comprises the following steps of burdening a tipping paper, measuring the delta E and the delta Lab, and adjusting a color scheme to manufacture samples; establishing a product match color database; determining whether the products exist the chromatic aberration by carrying out the match color data comparison on the samples and a master standard; finding out the permissible deviation of the color and the luminosity of each product, and determining the chromatic aberration of the products to determine the values of delta E; collecting and gathering the values of the delta E of the products, and establishing a database to obtain a chromatic aberration determination condition model. According to the present invention, by establishing the product match color and examination standards, the match color and chromatic aberration examination operation links are standard, the burdening time and the unit consumption are reduced, and the production efficiency and the product quality are improved.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging, in particular to a method for judging the color difference of tipping paper for cigarettes. Background technique [0002] Cigarette tipping paper is an important material for the production of cigarettes. It uses tipping paper base paper as the base material, and through pre-press design, printing processing (or coating) and post-press processing, the filter tip and cigarette sticks are combined. A kind of special paper that is connected. Among the control indicators of tipping paper, chromatic aberration is the focus and difficulty of control. [0003] Color difference refers to the size of the color difference between the printed matter and the original manuscript. Only when it is controlled within a certain tolerance range, the printed matter is qualified. At present, most domestic enterprises use the "visual method" to color match and inspect printed products. This method has th...
