Quality evaluation method of color ink-jet paper based on multi-layer grey relational evaluation

Abstract

The invention relates to a quality evaluation method of color ink-jet paper based on multi-level grey relational evaluation. The quality evaluation method comprises the following steps of: selecting a plurality of types of the color ink-jet paper which needs to be evaluated, and measuring basic physical performances of the paper; selecting a professional photo printer to sequentially print professional test versions, color scales and images on paper samples; measuring attribute printing performance of the printed images by an instrument; based on modeling which applies the multi-level grey relation technology to a comprehensive evaluation system, analyzing a plurality of evaluation data of the paper samples, calculating the relation degree of each type of the paper samples, finally establishing a printing quality evaluation system of the color ink-jet paper according to a multi-level grey evaluation model and then testing sensitivity of the system; and distinguishing the relationship among various influence factors according to a relation degree matrix. The quality evaluation method has the following beneficial effects that: a qualitative and quantitative evaluation result is obtained by applying the model based on the multi-level grey system to quality evaluation of the color ink-jet paper, thus solving the difficult problem that the overall quality of the color ink-jet paper is difficult to be scientifically and accurately evaluated in the printing field, obtaining the scientific and quantized comprehensive evaluation result of the paper quality, reaching a more scientific and accurate effect without judgment depending on subjective consciousness of a person, and playing a certain reference role in establishment of quality standard of ink-jet printing of the color ink-jet paper.

Description

Technical field [0001] The invention belongs to the field of printing or papermaking, in particular to a color inkjet paper quality evaluation method based on multi-level gray correlation evaluation, and is mainly applied to the quality evaluation of color inkjet printing paper (abbreviated as color inkjet paper). Background technique [0002] Paper products are mainly used as production materials, and more than half of them are used as printing materials. Color inkjet paper is a product of paper deep processing. It is a special coating treatment on the surface of ordinary printing paper to improve the surface quality of the base paper, so that the paper has good ink absorption and ink fixation, so as to maintain the original Some colors and clarity to obtain satisfactory printing results. Generally speaking, color inkjet paper is mainly divided into matte color inkjet printing paper and high gloss color inkjet printing paper. The image printed by high gloss color inkjet paper i...

Problems solved by technology

However, at present, people use these methods to detect the printing quality of inkjet printing paper or stay at the stage of detecting some performance indicators, and the results obtained are often only some discrete index data values, which can only define the printing performance of a certain aspect of the paper. In the end, people still judge which inkjet paper has better overall printing quality through subjective consciousness, and it is still impossible to get a scientific and accurate comprehensive evaluation result.
