Problems solved by technology

In the prior art, a combination of the principle of minimum mean square error, spectral color matching and tri-stimulus value color matching proposed the "excited spectral color matching method" to study the spot color matching of offset printing inks. Compared with other color matching methods, this method fully embodies the The color pattern of the ink reduces the degree of metamerism and improves the accuracy of color matching. However, this method does not consider the cost of color matching inks and cannot effectively reduce the ink cost of the enterprise. Especially when fluorescent inks are matched with ordinary inks, color matching inks should be considered. Cost is particularly important, so further research is needed

Embodiment Construction

[0023] A method for matching offset printing spot color inks in consideration of cost, the method comprising the following steps:

[0024] Step (1): Save to the database, that is, save the price parameter P of all base color inks participating in color matching i , (i=1,2,...,M), M represents the number of base color inks involved in color matching, and the price parameter P i It can be obtained through market research, or obtained from the manufacturer. The base color ink is fluorescent ink or offset printing ink; use a spectrophotometer to read the spectral reflectance value ρ of the sample to be prepared s ; Use a spectrophotometer to read the spectral reflectance value ρ of the substrate t , the substrates are printing substrates and blank substrates;

[0025] Step (2): The purpose of building a database is to obtain Φ, which is used to characterize the color matching parameters of each ink participating in color matching, that is, the ink unit concentration value matr...

Abstract

The invention discloses an offset printing spot color ink color matching method considering the cost factor. The method comprises the following steps of (1) storage into a database: price parameters Pi (i is from 1, 2 to M) of base color ink are stored, and the M shows the price number of the base color ink participating in the color matching; (2) base building: the base building aims at obtaining fai, i.e. the value matrix of the ink unit concentration is obtained; (3) ink color matching precision and color matching cost considering: the solved target optimization function ci is the concentration of each kind of ink are is a parameter to be optimized; and (4) solving: the formula can be solved by a simplex search method, when the minimum value of the formula is solved, the ci value can be solved, and the cost of the ink participating in the color matching can be known through ci. The offset printing spot color ink color matching method has the advantages that the offset printing spot color ink color matching precision can be more precise, the color matching efficiency is greatly improved, meanwhile, the use cost of the offset printing spot color ink can be effectively reduced, and the industrial application prospect is realized.

Description

technical field [0001] The invention relates to a method for matching offset printing spot color inks, in particular to a method for matching offset printing spot color inks in consideration of cost. Background technique [0002] With the continuous development of printing technology, the requirements for the quality of printed matter are also continuously improved, and for color halftone printing, the color rendering effect of printed matter is one of the most important factors for evaluating the quality of printed matter. Therefore, it is very important and extremely complicated work to accurately grasp the color rendering mechanism of printed matters. [0003] The use of spot color inks can reduce the number of printing plates, the number of printings, and effectively use the remaining ink, so spot color inks are widely used in printing companies. In a market with many branded products, spot colors can reflect the brand effect of the product and have an advertising role ...
