Re: [QuadtoneRIP] Re: Lightroom and QTR for Windows -- advice for an export for QTR strategy

Thanks all,

I was having similar problems too, and this workflow seems to work for the best for me too.

I often need to export into Elements, but then I can reimport the TIFF to LR.  I was worried that LR may do some underhanded file handling during the export.

 It’s this insight that led
 me to trying the approach I described here (i.e., getting
 the image “right” on my calibrated monitor in Lightroom,
 then exporting with a linear ICC – Roy’s
 RGB_Matte_Paper.ICC, and then printing in QTR with attention
 to Ink Limit values). Note I also tried it with the ICC I
 made for that paper and ink, reading the L values from a
 print of a 21 step chart with a known even distribution of
 gray values; there was no difference to my eye in shadow
 detail compared to the export with RGB_Matte_Paper.ICC.
 Exporting with either seems to have lined things up properly
 in the shadows.
 
 
 My guess would be that this is the
 most straightforward approach.  Just set up a
 Preset for this Export:-- TIFF, convert to
 RGB_Matte_Paper on output, some reasonable PPI like
 360.
 You should be
 able to use this  on any matte paper for decent
 screen/print match.Set up a second one if you do
 Photo paper too.

 BTW, several posts talk about a
 "linear" ICC/color space.  The QTR driver curves
 are linear in L - Lab space,but end points are
 dMin and dMax which makes them a little different than
 editing spaces -- such asQTR_RGB_Lab, or gamma
 spaces.  The linear with dMin and dMax are what the
 RGB_Matte_PaperICCs match.  Since all the curves
 are linearized we get to have these "generic ICCs"
 that workwith many papers.
