Accurate color measurement tools can help you test your paper for color and consistency, resulting in a higher-quality final product. Image source: Pexels user Tim Gouw While visiting a friend’s home, I noticed an enormous, beautiful painting hanging above the fireplace. Up close, I could see what looked like real paint clinging to the surface […]
ERIC stands for Effective Residual Ink Concentration and is a control parameter used to quantify the amount of residual ink left in recycled or de-inked pulp (DIP) and paper before and after de-inking and/or bleaching processes. Other parameters measured are brightness and dirt content. Based on joint research by PAPRICAN (Pulp And Paper Research Institute of […]
Contrast Ratio Opacity measurement quantifies how opaque a sheet sample using two readings. One reading is taken with the black glass or light trap backing the sample at the port. The second reading is taken with the sample backed by a white tile or the white sample clamp insert. EasyMatch QC will prompt you for […]
