Optical Brighteners and UV in Paper Measurement
Understand how optical brightening agents and instrument UV content change paper and print measurements, and how M1, M2, ISO and D65 conditions should be controlled.
Technical guide · Read the guide →Aperture Size
Measuring Textured Coatings
Measure textured coating color with an aperture and sampling plan large enough to represent peaks, valleys and directional structure without hiding local variation.
Technical guide · Read the guide →Aperture Size
How to Measure Small Parts and Small Color Samples
Small-part color measurement depends on the true viewed and illuminated areas, precise targeting, controlled backing and a fixture that reproduces position and angle.

UV Control and Optical Brighteners in Color Measurement
Understand how UV included, UV excluded and UV calibrated conditions affect optical brighteners, whiteness and agreement between spectrophotometers.

Measurement Aperture Size Explained: Why It Matters
Aperture, illumination area and detector view are not always the same. Match the instrument’s usable measurement area to the sample and method.
Quick technical guide · Read the guide →Inter-Instrument Agreement
Spectrophotometer Repeatability vs Inter-Instrument Agreement
Repeatability shows how closely one spectrophotometer agrees with itself. Inter-instrument agreement shows how closely it agrees with another. Learn why both matter for reliable color control.
