Method for identifying primary color ink of spot color mixed ink and electronic equipment

Abstract

The invention discloses a method for identifying primary color ink of spot color mixed ink and electronic equipment, and the method comprises the steps: pre-establishing a database comprising the attribute information of a plurality of primary color inks and the attribute information of a plurality of standard spot color mixed ink, and recording each spectral reflectivity in the database as a first spectral reflectivity; obtaining the spectral reflectivity of the target spot color mixed ink, recording the spectral reflectivity as second spectral reflectivity, and performing difference pretreatment operation on the first spectral reflectivity and the second spectral reflectivity respectively to obtain a corresponding first processing result and a corresponding second processing result; comparing the first processing result with the second processing result, and selecting a predetermined number of ink matched with the color of the target spot color mixed ink from a database; calculatingthe probability of occurrence of each primary color ink according to the frequency information; and selecting a plurality of high-probability primary color inks as the primary color inks of the targetspot color mixed ink according to the probabilities. Therefore, the efficiency of spot color ink color matching can be improved.

Description

technical field [0001] The invention relates to the field of color matching of spot color inks, in particular to a method for identifying base color inks of spot color mixed inks and electronic equipment. Background technique [0002] The color matching of spot color inks is based on the color mixing theory, and the same color effect as the target color can be obtained by blending the base color inks (cyan ink, magenta ink, yellow ink, black ink, etc.). [0003] That is to say, spot color ink matching is a method of identifying which base color inks are used in the target ink. The traditional spot color ink matching method is to rely on the operator's many years of skill and experience to match the color through observation or comparison. It is generally suitable for small packaging printing with low color requirements. However, there are problems of large color difference from the original and high defective rate during use. [0004] In recent years, another spot color in...
