Spectrophotometer for Paper Color Measurement

纸张颜色测定分光光度计

Tinted papers, coated grades and print proofs must match a target shade, and this spectrophotometer gives the numbers to prove it. It scans 360–750 nm at 10 nm steps with d/8° and 45/0° geometries. Repeatability is below 0.05 colour difference, and inter-instrument agreement typically below 0.2.
