Digital BW, The Print

Thanks for your help and all the work you've done to share your experience.

From your description of what you think should be done for a gamma 1.8 workflow, it seems that what I've done should have worked.  I tagged the target G1.8 and ran it through ImagePrint.  I did use the 51 patch target instead of the 21 patch.  I will try the 21 patch in case Eye-One measurement error caused non-linearities.

I will let you know if this worked.

ImagePrint does have a reasonably accurate soft proof for 8 bit images (Hi-rez view) in the layout window.  But that doesn't help when editing the image in PhotoShop.  Other than the tint picker for B&W mode, you don't want to use any of the correction tools in IP, they suck.

Thanks,

Eric

  Hi Eric,

  I haven't tried any gamma 1.8 workflows but I think this is what you need to do.

  You need to get everything into gamma 1.8 spaces.
  Assign Profile ... Target-21.tif file to Gamma 1.8   (not Convert to Profile).
  I'd switch the Color Settings ... as well to gamma 1.8 and Apple RGB or
  some other gamma 1.8 color space.  I don't think this is critical but if any
  conversions get done they are in the correct gamma.

  Now print the Target through ImagePrint and follow the same profile
  creation method.  This profile ought to be useful for gamma 1.8 files.

  As far as converting color images to grayscale 1.8, whenever you Convert
  to a different gamma space you change the data values.  Whereas Assigning
  just changes the space name not the data.  If you are going to be editing
  in the new gamma 1.8 space based on the softproofing I don't think it
  matters.  I'd try to get it into the right space while still in 16bit if possible.

  (BTW, doesn't ImagePrint have any softproofing capability?).

  Roy
