Dumb questions

Do you print greyscale or RGB? QTR seems to do it's thing the same regardless of
what mode you are in, so it would be better to use the smaller file.
And, yes, I hate to admit it, but I'm one of those who don't know the difference
between curves and ICC profiles.

I'll let someone else explain the technical aspects of a curve and an ICC profile, but for one thing--you cannot use a curve in place of a profile.? An ICC profile is, for instance, the color space of your monitor, the working space you use in PS, the paper profiles you choose for printing (and then make sure your printer chooses 'no color adjustment').? The curves are what QTR 'tells' the printer as to how to use what colors (what nozzles to use).? There will be someone that can tell you much better technically the differences--hopefully.?
?
If you using a PC, you will want to convert your RGB image to Gray-LAB (which is an ICC profile--and should be in your dropdown in PS).? Do any tweaking here (I won't go into softproofing here), save this as a 'master' file in tiff.? Then--convert this file to Gray-matte or Gray-photo (both ICC profiles--you will find these 3 in a zip on the QTR download page--the RGB profiles are for use in Qimage)?depending upon the paper you choose to use for printing.? Having the master in gray-LAB allows you to go back and print easily on a matte or semigloss/gloss paper.? You will choose the gray-matte or gray-photo tiff to use in QTR.
?
Hope this helps.
