What's very interesting as well is measuring the base of the substrate ,
especially when there is a uv coating or other varnish on substrates other
than offset paper stocks. Seems that the fibers of the base combined with
the coatings can effectively be read by a sphere instrument lending to an
accurate white. Would the 100 readings then fare better in this case than
the 20 on the same spectro?
