Printing color and latitude visual inspection system device and application method thereof

Abstract

The invention discloses a printing color and latitude visual inspection system device and an application method thereof. The printing color and latitude visual inspection system device is composed of a rectangular ruler-shaped main body and monitoring color bars, the main body is a neutral gray color value region and is formed by combining every primary color and every secondary color in percentage; the main body and a plurality of replaceable color lumps are all functional areas with visual inspection hue contrast information, the main body is also provided with color monitoring information areas for comparing an upper limit and a lower limit visually, the color monitoring information areas can directly provide hue latitude information, the monitoring color bars are provided with a series of monitoring overprinting indication functional areas which are closely connected, and the paralleling and the ranking correspond to a system main body. The printing color and latitude visual inspection system device utilizes a gray balance technology, accords with printing standard data and is applicable to mechanical and digital printing processes, measuring instruments are not needed in the application method, a scheme can be modified by directly comparing a set color value visually, rapidly and in a point to point mode, the production changes can be known timely, loss can be reduced, and the aim of controlling the operation in a high-quality production environment with the lowest error rate can be achieved.

Description

technical field [0001] The invention relates to a printing quality monitoring device and a using method, in particular to a printing color and latitude visual inspection system device and using method. Background technique [0002] The existing technology of primary color printing color control comparison is to use the image on the product as a direct comparison between the sample and the printed image in a large area, but the image interpretation is a full color gamut, and the result is that there is no established standard for the original color weight. There is no systematic sorting, the controller can only directly compare the content color difference of each image, rely on subjective estimation of the primary color value of each ink area to increase or decrease, there is no uniform way to determine the color value correction of each ink key area Program.

[0002] The existing technology of primary color printing color control comparison is to use the image on the product as a direct comparison between the sample and the printed image in a large area, but the image interpretation is full of colorful colors, and the result is that there is no established standard for the original color weight There is no systematic sorting, the controller can only directly compare the content color difference of each image, rely on subjective estimation of the primary color value of each ink area to increase or decrease, there is no uniform way to determine the color value correction of each ink key area Program.

[0003] In printing color management tools, some people claim that solid color blocks are used as functional color blocks, and printed on the product as a test target, which can be used for visual comparison. There is no connection and intercommunication information between the color block and the same color block of another cycle, so each independent color block is set in segments at a fixed distance, so the visual comparison cannot be implemented without technical support

[0004] In the prior art, the printing color detection method is to use the printing color blocks printed on the product, also known as color sticks, to provide the target color value information after the printing production is completed. The color information is messy and leads to visual confusion. This color stick is impossible. Visually determine the required color value of each independent primary color solid color, accurately provide dot value-added rate, clearly reflect the physical state of the machine, etc. The result is that the production is operating in an environment with a large error rate, and the waste products are also increased. question
