Test Principle ：

The equipment consists of a stainless steel bracket, precision engraved metal anilox roller and solvent-resistant rubber roller. Fixed-volume cells are engraved on the surface of the anilox roller to control ink loading and ink film thickness. The pressure between the rubber roller and anilox roller is adjustable. Place a small amount of ink into the roller nip. Pull the manual proofer at a constant angle and uniform speed. The anilox roller transfers a fixed quantity of ink onto the surface of the substrate to produce a continuous, uniform color strip in one pass, for visual color comparison or spectrophotometric color measurement. Different anilox line counts (LPI) correspond to different ink loading rates, matching various printing conditions such as solid areas and halftone dots.
