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.
