Computer color matching
Color matching instrument
Computer toning formula and its management have been successfully used in plastic color matching.
The computer color matching instrument has the following functions:
1) Color matching
Establish a database of commonly used colors (dyeing) materials according to requirements (preparation and input of basic color palettes). Then input the incoming color palette into the computer under the software menu, click several candidate pigments in the keyboard, and immediately calculate a series of formulas, and list them in order of color difference and price for color matching;
2) Formula revision
Correct the computer to list formulas and formulas from other sources. When the color difference is unqualified, use the inconsistent reflection curve displayed on the display to directly increase or decrease the amount of pigment through the keyboard until the two curves basically overlap, and the revised formula is obtained;
3) Color measurement and color difference control
Measure the color strength of the colorant, the whiteness of the product, the color fastness of the product, and the color difference. Since the computer can quantitatively express the color performance index, it is conducive to the communication and transmission of information between the two parties;
4) Color management
The color samples, formulas, process conditions, production date and user information in daily work can be stored in the computer, which is convenient for retrieval, search and reference when modifying, which is convenient and fast, improves work efficiency, and facilitates confidentiality.
