Sample Scratch Card

A drawdown card is a tool used in the paint and ink industry to compare colors and hiding power. The principle involves using a standard drawdown blade to evenly spread the sample on a card, forming a film layer with gradually decreasing thickness. Its purpose is to visually display color distribution, leveling, and hiding effects. It is applied on the production site for quick color difference comparison, inspection of product hiding performance, and printability.
Selection
The selection of scratch sample cards should consider the substrate's whiteness and ink absorption, with medium-white card paper being commonly used; observe the coating uniformity in the scratch sample area; choose the corresponding size according to the testing standards; pay attention to the flatness and texture-free surface of the card paper; match the industry's general specifications to facilitate horizontal comparison.
