There is a vector/raster element here, but another factor is scanner versus
spectrophotometer... the light source in your scanner is not at all like the
one is your spectro... and the results may differ due to metamerism. Yet
another issue is that currently scanners are profiled with a photo based
target, which is not necessarily appropriate for other media. Using a fabric
based target with a custom data file built with the spectrophotometer would
assist in getting better results.
