Prospective intelligent control method and device for fluid printing color film

Abstract

The invention provides a prospective intelligent control method and device for a fluid printing color film. A color quantity of a printing process is controlled by controlling a thickness of a printing color film. The method comprises the following steps: firstly, setting a color film thickness standard, and starting a material storage groove and outputting a raw material to a grinding system so as to evenly grind the raw material to form a color film, enabling the color film to pass through a sample rotating shaft; measuring the color film on the sample rotating shaft by a measuring instrument, and comparing the acquired data with a reference target by an analyzer, wherein a neutral grey balance production process is adopted in the reference target; and transmitting a color film correcting value in real time to a production equipment control console by the analyzer. The feeding of the material storage groove is controlled by a raw material grinding production system so as to correct the thickness of the produced color film and repeatedly operate in a circulating manner, thereby being capable of reaching the optimum pigment volume and the minimum error tolerance, precisely controlling the production of high-quality products and reducing loss. Changing the hysteretic control in a system for monitoring finishing products into the prospective intelligent control is the great improvement for the printing color film control and the device.

Description

technical field [0001] The invention relates to a control method and device for producing fluid printing color film. Background technique [0002] In the printing industry, the color value of the printing color film is a very important indicator that affects the printing quality. Accurately using the appropriate color value for printing is an important issue to improve the printing quality. [0003] To measure the color value in the traditional printing process, an optical densitometer or spectrometer is used to obtain the density color value. To obtain the measurement value, it is necessary to add a measurement function color block with a test sample on the printed matter to read the density and color value data for the purpose of adjusting the color value. [0004] The detection method in the existing technology is the "hysteresis" detection method, and the conveying system of the traditional production process is not equipped with monitoring equipment.

AI Technical Summary

Problems solved by technology

"Automatic" means that the product quality monitoring system is set in the downstream of the production process, with a specially designed color stick, which contains the color gradation composed of each primary color, and is printed on the product together, but the color stick can only monitor each primary color. Solid color density, providing color value variation results

No matter which method depends on the completion of the product, the need for hysteresis confirmation and correction will greatly delay the adjustment time and increase the number of defective products produced.

The traditional method adopts the hysteresis test method, and all the testing processes basically have the following disadvantages: the detector is set in the downstream of the production process, and it is "lag" to test the quality of the finished product; the traditional method that needs to print out the test target is commonly used The color bar is used to provide the testing environment. The testing environment only simulates the quality status of the product, and it is impossible to 100% actually reflect the quality results of the full coverage area of ​​the product; based on the "hysteresis" testing method, the testing results require analysis time and setting Correct the plan and then carry out the corrective action. The corrected result is a delayed response and leads to an error in the corrected completion time.

This is not a "direct" control quality value, but the simulation information in the "second and third round" color sticks is selected for correction, and the "indirect" detection results are obtained, which greatly increases the number of defective products
