PP hollow sheet is not only practical, but also has a variety of different colors for choice, manufacturers can be customized in accordance with the color needs of customers, so how is the color of PP hollow board deployment?
1. Hollow board color matching: according to the requirements, the database of common colors (dyeing) is established (the basic color board is prepared and input). Under the menu of the software, input the color board into the computer, point out several candidate pigments in the keyboard, immediately calculate a series of formulas, and respectively by color difference and price order listed for color selection;
2.hollow sheet formula correction: correction of the computer listed formula, formula from other sources, when the color difference is not qualified, using the display of the inconsistent reflection curve directly through the keyboard to increase or decrease the amount of pigment, until the two curves basically coincide, get the revised formula;
3. Color difference control: measure the coloring strength, whiteness, color fastness and color difference of the colorant. Because computer can express the performance index of color quantificationally, be helpful for both sides information communication and transmission.
4. Color management: the color sample, formula, process conditions, production date, user and other information used in daily work can be stored in the computer for easy retrieval, search and reference for modification, which is convenient and fast to improve work efficiency.
