QTR-Quadtone RIP

Mike,

Ah, so you use Qimage's sharpening system, save the image it alters, and then send to QTR?  I'll try it!

Fwiw, I did try same image in PS.  It might be a bit more contrasty than QTR and slightly sharper than QTR for that fact, but I suspect some of that is due to it not utilizing all the K7 inks as would QTR as a RIP.

However, Qimage is still very apparent for sharpness over either PS CS6 or QTR - so far - even though it may be using the same K7 inks as PS does.  QTR's "unsharpness" that I'm seeing may be the lower density inks coming into play too.


I'll try the "File Save" in Qimage and print one via QTR and see what happens...

Just to make absolutely sure, what I meant was:
set up in Qimage as if you are going to print (size, print settings
    and image) and then instead of printing to printer,
Go to 
File -> Print to -> File
File -> Printer/Page Setup 
  - set page width and height to desired IMAGE size, and set
    resolution
  - set sharpening to what you want (I don't know what it defaults
    to)
then 'print' and select where to put the file, and finally open the
    print file in  qtrgui - DON'T LET QTRGUI RESIZE - and print!

works for me!

>Thanks Mike, but that's pretty much what I've done (printing at 360 in Qimage).  QTR is not sharp, but a soft blur from same image.  Items like concrete detail, hair strands, small text (I watermark small white print in PS and it's very obvious there.) are razor sharp with clean edges from Qimage.

              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.

              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.

              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.

              tech did call me on size and said the image is very sharp
              on his monitor.  Should be interesting.
