I think some of the problems I'm having is due to the fact that many of the
greens and oranges on the printed profile target do not print as a flat
color. The swatches look very textured (marbled), much like the a metallic
paint finish on a car only enlarged. The blues print fine and most of the
reds print flat. The greens and oranges look almost multi-colored which
probably drives the spectrophotometer crazy. I'm getting these effects on
coated canvas and coated watercolor papers.
Yes Michael, there is someone out here with a similar problem and
Chris Murphy is mostly right when he says averaging over a series of
samples is the way to go. The other consideration you have to allow
for is whether or not the substrates on the media you are using can
accept the type and density of ink you are using.
Dye inks on textured media give you steadier swatch overall but you
currently lose archive-ability. Pigment inks are more archival, but
you sacrifice some of your gamut (and density/saturation on single
pass printing) and, most importantly, are reliant on the substrates
in/on the surface of the media which determine how much the ink sits
upon or sinks into the media itself.
Currently I am profiling third party canvases (matte and glossy)
using PrintOpen 4.0 (MAC). On the matte I am averaging three to four
test swatches per round and have yet to get my ink density set.
Close, but the rough surface reeks havoc on the CM2s spectro.
Recently I'm having better results measuring using a 10 degree
sampler than the usual 2 degree. I'll get back to you on how well
this works with my other media. However, this means I have to sample
outside PrintOpen and import the data, but the results are worth it.
Anyone out there with any further input on this subject would be more
than welcome.
