Digital BW, The Print

This brings to light a serious deficiency in the old PiezoBW workflow...it
wasn't really color managed...meaning...you couldn't simply edit in a
standard "color" space (Gamma 1.8 or 2.2) and expect to get screen to print
match.  What this really reflects is that the profiles were bad and required
further tweaking via custom dot curves to actually match the screen.  Of
course this was always passed off as being individual differences in
printers...which may be true to an extent...but it certainly doesn't appear
to be a major problem with the Imageprint workflows that I've
tried...profiles made from other people's targets are usually right on the
money on my printer.

As a result your older files will have to be redone now that you have moved
to a color managed workflow.  Of course, if you have the original files from
either your scanner or digital camera then these are probably tagged with
either 1.8 or 2.2 (or their equivalent in the color world, e.g., colormatch,
sRGB or Adoble 98, etc) and you can work from there.
