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

Embodiment 1

[0089] Embodiment 1: A forward-looking fluid printing color film intelligent control method and device

[0090] see figure 2 , including: production equipment console (7), production units 1, 2, 3 and 4, grinding system (52), scanner (5) and neutral gray balance analyzer (6). Its production color group units 1, 2, 3 and 4 are freely arranged according to requirements and placed black, cyan, magenta and yellow pigments on the storage tank. Input the preset black color value to the neutral gray balance analyzer (6) as a reference for neutral gray balance production. The analyzer prepares the correspondence table between the thickness of the printed color film and the amount of the monitored material in advance ( Figure 20 ) to determine the thickness of the grinding printing color film. Black, cyan, magenta, and yellow color zone scanners (5) measure the printing color film sampling thickness (9), and actively provide a neutral gray balance analyzer (6) and preset black colo...

Embodiment 2

[0091] Example 2: An independent regional production unit forward-looking fluid printing color film intelligent control device

[0092] see image 3 , Each production color group such as: Unit 1 can choose a special color for production. The scanner (5) extracts the color value data of its color group unit in a regional active look-ahead manner. Uneven color zone results will be directly sent to the color zone controller (8) of the color group for real-time cyclic correction without correction through the console (7). The operator can also use the device console (7) to select the color zone value. Other similarities with the above embodiments will not be repeated.

Embodiment 3

[0093] Embodiment 3: A forward-looking fluid printing color film intelligent control device with a built-in monitor

[0094] see Figure 4 , production equipment machine structure (13). The single monitoring instrument fixes the rotating shaft (10), and the measuring probe (5) operates back and forth in the direction of the arrow. Along the motorized rotating shaft (10), the probe is driven back and forth to scan the surface of the color film thickness sampling rotating shaft (9) accurately. The reading value of the film thickness is connected by optical, electrical and digital transmission (11), and the data is transmitted to the operation system of the PLC program control cabinet (12), and the conversion result becomes digital, which is used as an active and forward-looking production system for continuous monitoring and correction. use.

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. Check its eligibi...
