Inkjet printing quality fuzzy evaluation method

Abstract

The invention relates to an inkjet printing quality fuzzy evaluation method which is characterized in that the image acquisition technology is used for realizing the transformation between inkjet printed images and digital images, and the evaluation performed by the human visual system to inkjet printing colors is simulated based on a S-CIELAB color space; by utilizing the mass distribution theory, the ink absorption amount of inkjet printing paper for a single pixel point is simulated; and by utilizing the measure theory, inkjet printing clarity quality is estimated. On a basis of the colors and the clarity quality and with a combination of human visual characteristics, an inkjet printing quality fuzzy evaluation algorithm is established, and a numerical value Image-QAIJP is given to the algorithm. The method has few test data and fast speed, effectively overcomes the defects that a printed image quality subjective evaluation method wastes time and money, and a conventional objective evaluation method is single or is not matched with an actual image quality, and provides an effective measure for inkjet printing quality analysis. In addition, the needed matched apparatuses are simple, are low in cost and convenient to use.

Description

technical field [0001] The invention relates to a fuzzy evaluation method of inkjet printing quality, which uses mathematical measurement formulas to objectively quantify the inkjet printing image quality evaluation results in the observer's mind, and is applicable to the method for detecting inkjet printing quality in the fields of printing and papermaking. Background technique [0002] Color inkjet printers involve more and more fields, and the corresponding increase in the consumption of inkjet printers and inkjet printing paper makes people have higher and higher requirements for the quality of printed images. Therefore, the quality information of images must be detected and Analysis, so as to control and improve the combination effect of paper and ink. In recent years, scientists have made many advances in the quality evaluation of printed images. [0003] The density value in the traditional measurement technology can not achieve the evaluation results of human eyes, ...

Therefore, the ISO13660 standard cannot be used for the evaluation of the printing quality of inkjet printing paper.

[0006] People have been able to evaluate the quality of inkjet printing on the micro and macro scales with the help of computer image analysis methods and digital image analysis methods, but there is still a gap between the image quality measured by mathematical measurement formulas and the image quality evaluation results in the minds of observers. difference
