QTR-Quadtone RIP

I recently made a few curves using the RAW curves as a baseline. PC.
- You choose the closest RAW curve to the type of paper. - Rename- Print a 21x4 Random target. - Read it using a spectro. - Drop it on the linearize thingy and a txt (out) file would be created. - Copy the values on the "linearise" line of the txt file- Open your the RAW curve that you have renamed via the Curve Creation- Input the Values- Click Show Curve (to save the adjustments)- Done.
-Print Print a 21x4 Random target again, using the Curve that you just did.- Read it using a spectro. 
- Drop it on the linearize thingy and a txt (out) file would be created. - Copy the values on the "linearise" line of the txt file- Open your the RAW curve that you have renamed via the Curve Creation- Input the Values- Click Show Curve (to save the adjustments)- Done.

 Subject: [QuadtoneRIP] Re: Transferring curves from Mac to Windows

    That was my understanding too, but I've recently read some instructions that offer a simpler approach.  There are some (but not all) printers for which QTR ships with a "raw" or generic set of curves.  These instructions suggest that you first try linearising these curves and seeing how close you get.  Only if the results are not satisfactory do you go to the next stage and print the separation page and set your own ink limits etc.  I've never tried this simpler approach using raw curves, so I have no idea how well or how often it works.  There don't seem to be raw curves for the high gloss printers (R1800/1900/2000).


From what I can gather and recall, the original Tom Moore instructions were written from a Windows perspective a decade ago, before there were sets of raw curves, and when the whole process of curve creation was fairly new.  So it was a fairly detailed and lengthy document.  The more recent instructions were written from a Mac perspective and are fairly concise.  So it may initially appear that the approaches for curve creation for Mac and Windows are different, but they're not.  Of course where the files are stored and how you install them is different, but the principles of curve creation are the same.  #yiv3166408913 #yiv3166408913 -- #yiv3166408913ygrp-mkp {border:1px
