Digital BW, The Print

I just wanted to add a word to Tyler's great post.

People seem to neglect color management because they are working with grayscale inks. This is really the wrong approach. If anything color management is even more important because we are often concerned with very subtle changes in hue that are much more difficult to control.

This is a complex topic and not something that is easy to achieve in terms of time, effort and money, but please keep it in mind if you really want to get the very best out of your systems and processes.

  Subject: [Digital BW] Cross platform issues was Tyler Boley's bs (help me C.D.!)


  Carolyn is right. Color managed workflows, in my experience, are cross platform. You can't avoid color management any 
  more, if you are working in Photoshop, you are being managed whether you like it or not so you might as well learn it. 
  Actually, it's essential, but there are some pitfalls to avoid so it all works.
  You must avoid letting the Epson driver inject it's problems into the mix. With quads, using separations, you want all your 
  control in photoshop to be transferred to the inks without further mixing. Considering you can't get around the drivers 
  injection of K ink and the removal of other inks in the process you already have problems, you don't need more. The only 
  way to directly control C, M, and Y inks (until their combined percentages force K) is to stay in no color adjustment in the 
  driver.
  You also must have your destination space be "same as source" or there will be color managed corrections you don't need 
  or want. The other issue is "Printer Color Management". C. D. Tobie, who I notice has been on this list a bit, just posted about 
  it on the Colorsync list. It does different things on different platforms, and is very misunderstood. I think, on the PC, it even 
  does different things with different drivers, and different versions of PS. There is a lot of info out there in the archives of 
  other lists.
  By making sure your source and destination spaces are clearly defined and the same, making sure PCM is out of the 
  picture, driver settings are always consistent, and no color adjustment is always used in the Epson driver, results should 
  be cross platform. I've produced workflows on the Mac for people on PC's without a problem. These curves for Martin's PC 
  were created on a Mac.
  The PCM issue needs to be addressed though, if I remember right in PS 5.x on a PC it actually had to be checked or the 
  monitor profile would be used for source behind your back. Could have been the reverse, but I seem to recall it was 
  opposite for the Mac.
  Confused yet?
  Tyler
