I need to profile a textile media for a large format printer
II have no specific experience with the instruments you mention, but I have worked with textiles. What differentiates textiles from most other media is their strong surface texture. The incident angle of the illumination can have a strong effect on the reading. For example, 45° illumination creates shadow areas behind each raised fiber which will be "seen" by a 0° sensor. Diffuse illumination may be useful to alleviate that problem. The above assumes that you are printing on fabric woven with a single weave - the usual case for printing. Dobby or Jacquard woven fabrics, which contain many different weaves, create a much larger set of problems... -- Garth Fletcher
