Embodiment 1

[0031] A high-precision printing equipment color registration control system, the system includes: a first analysis unit, used to analyze the analog voltage signal generated by the photoelectric sensor in the automatic color registration system, and obtain the key parameters of the analog voltage signal; the extraction unit uses Extracting an effective voltage signal in the analog voltage signal according to the key parameter, the effective voltage signal is a signal generated when the photoelectric sensor detects a color mark; an error analysis unit is configured to, based on the effective voltage signal, Perform data analysis on the voltage signal to calculate the overprint error of the automatic color registration system; the color registration adjustment unit is used to adjust the operation of the color registration system according to the calculated overprint error.

[0032] Specifically, the so-called special printing is to use special equipment and special technology to ...

Embodiment 2

[0037] On the basis of the previous embodiment, the error analysis unit includes: a signal preprocessing unit, a signal specification unit, a signal standardization unit, an algorithm prediction unit, and a modeling analysis unit; the signal preprocessing removes signal information in sequence Unique attribute, processing missing value and outlier detection processing; the signal specification unit is used to perform specification processing on the signal after signal preprocessing, so that the signals after the protocol processing are irrelevant to each other, but keep the original information; The signal standardization unit scales the signal processed by the protocol to make it fall into the set interval; the algorithm prediction unit performs signal modeling according to the signal processed by the signal standardization unit; the modeling analysis unit uses The accuracy calculation is performed on the customer satisfaction signal generated by the calculation model and the ...

Embodiment 3

[0039] On the basis of the previous embodiment, the method for the signal standardization unit to perform signal standardization processing performs the following steps: perform signal standardization processing, and scale the signal to make it fall into the set interval; wherein, the following conversion is used Function, linearly transform the signal so that the result falls into the [0,1] interval, the conversion function is as follows: where x * is the result of signal normalization processing; x is the signal to be processed; min is the minimum value in the signal; max is the maximum value in the signal.

[0040] Specifically, before data analysis, we usually need to normalize the data first, and use the standardized data for data analysis. Data standardization is the indexation of statistical data. Data standardization processing mainly includes two aspects: data homogeneity processing and dimensionless processing. Data homogeneity processing mainly solves the proble...

The color register control system has the advantages of being high in intelligent degree and automatic in control.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a high-precision printing equipment color registration control system and method. Background technique [0002] In the printing and dyeing industry, how many colors need to be printed and dyed on a product is called several sets of colors. The printing color sequence of four-color printing can have 24 different permutations and combinations. Only by selecting the printing color sequence that conforms to the characteristics of the ink and the overprinting rules can the color of the printed matter be more faithful to the original manuscript, and the image level and dots are clear. gray balance. [0003] Color registration generally needs to ensure the following requirements: [0004] (1) The color sequence of the ink with poor transparency and strong hiding power is at the front, and the color sequence of the ink with good transparency is at the back; [0005] (2) Black is in ...
