Problems solved by technology

[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

Embodiment 1

[0110] Embodiment 1: A kind of printing color and latitude visual inspection system device and using method, such as figure 1 As shown, it is a schematic diagram of the system main body and the monitoring color bar of the device. The main functional ruler-shaped plate of the external device is compared with the special monitoring color control color bar. The material of the ruler-shaped plate (1) can be paper (board), metal, For wood, plastics, glass, synthetic thick materials, pottery, etc., the main part of the surface is to be coated with neutral gray (3), which is the basis of the neutral gray tone of the present invention as standardized color management. The color scale samples of each primary color and black solid color are (31, 32, 33, 34); the mid-halftone color scale samples are (41, 42, 43, 44), and the reference provided by these two areas matches the visual guide is a standardized color Manage the set color value and color gamut dot value-added rate. As long as th...

Embodiment 2

[0114] Embodiment 2: a kind of printing color and latitude visual inspection system device, such as Figure 5 As shown, it is a schematic diagram of the comprehensive structure of each primary color of the system main body of the device and the standard color area of ​​black and tolerance. The color blocks on the device main body (1) are all fixed color blocks, and one of the primary colors of the ruler-shaped plate of the external device main body and mid-halftones are merged with the color latitude ribbon into ( Figure 5 ). The standardized primary color solid color (31) and the standard dark color area (11) and the standard light color area (12) of the color tolerance are arranged on both sides; the standardized primary color halftone (41) and the standard dark color area of ​​the color tolerance (21) and the standard light-colored area (22) are arranged on both sides to become the merged functional area; Its standard tone depth (4) and light (5) such as neutral gray are ...

Embodiment 3

[0115] Embodiment 3: A printing color and latitude visual inspection system device, the main body of the system is divided into three parts: neutral gray tolerance scale, primary color and black tolerance scale, primary color, black and neutral gray standard color scale, see Figure 6-Figure 8 .

[0116] like Image 6 As shown, it is a schematic diagram of the gray tolerance structure of the system main body of the device, and a demonstration diagram of the gray tolerance structure of the ruler-shaped plate of the system of the device. The external plate is designed as an independent latitude visual inspection device. The color blocks for monitoring the upper limit (4) and lower limit (5) of the gray color value are constructed on the carrier (7) by printing, spray painting, dyeing, primary color casting, electroplating and coloring, and ceramic production. The carrier can be hard material or soft material. Manufactured from reversible material. The comparison method is to ...

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. [0003] In printing color management tools, some people claim that solid color blocks are used as functional color ...
