Thanks for that. I'm not sure, though, how it addressed the question of why
an integrating sphere spectrophotometer is better for measuring colour
samples on canvas or other course materials.
According to the information on the Hunterlab web site,
0/45 instruments a designed to measure the appearance of
color. They "see" like we do, and allow for the effects
that gloss, texture and directionality on the color
appearance.
The integrating sphere instruments do the opposite,
they measure the color in a manner that is independent
of the gloss, texture and directionality. They
effectively measure the "underlying" color of
things, so are useful for checking color formulations and
product consistency, particularly for materials with difficult
optical characteristics (gloss, transparency, translucency,
texture).
