Dear Lorenzo,
I totally agree with Garth.
An instrument with a 45°:0° geometry is not the best way to measure textile samples for the reasons he mentioned.
——Disclaimer—
I’m working for Konica Minolta and we are developing color management solutions
——Disclaimer end—
We, our partners and also our customers get very good results when they do the profiling using our d:8° instrument CM-2600d automated on an xy-stage.
„Very good“ for our customers means:
a) Large color gamut
b) Smooth gradations in separations
c) Very low dEs when they reproduce a reference (such as a textile preproduction or a sample like a color fan)
d) Very good correlation between measured dEs and visual perception -> They easily get a visual match between their print and the color fan for example
e) They can simulate the color output of their textile printer using a regular inkjet proofing system
So should you use the tools you have be aware that maybe you spend more money for materials for trial&error and reprints than you would for a solution that works right from the start.
Should you want to have more details feel free to contact me off-list.
Best regards
Claas
