Re: [QuadtoneRIP] QTR for WIndows is not producing sharp images.

I took the original and printed it in another 3880 in color and it is tack sharp, hair strands and text are razor sharp out of Qimage from it. The B&W is sharp as well out of Qimage into the K7 3880, other than the tonal range being different due to the K7 inks and QTR's ink management. I possibly could get a 21-step tonal range match if I apply a curve adjustment in the Qimage editor, and get a sharper image too in the process.
However, when I use QTR, the same image which is sharp through QImage becomes soft which is troublesome. Haven't tried printing it from PS CS6 yet, but might be worth a shot to see if it matches the unsharp image made from QTR. If it does, might prove Qimage is the better platform for printing - although it's not a RIP and unknown as to how the K7 inks would be used doing so.
My suspicion, for now, is the sharpening engine or whatever it is in Qimage, or the Epson driver (Probably not that.), following is superior for sharpness over QTR and maybe even Adobe as well if I try it in PS. Don't know if the Mac version of QTR is sharper over the Windows version, but getting soft prints sort of defeats using K7 inks with the Windows QTR version.
I'm turning the same job over to a lab with a different RIP and see what they do with the same image too. Their tech did call me on size and said the image is very sharp on his monitor. Should be interesting.
