Re: [Digital BW] Re: Epson Premium Printer Profiles for B&W Printing

2005-12-04 by Tom Husband

I know QI takes a grayscale and produces an rgb when interpolating and sharpening and that's what I use it for.  I don't print with QI I use its "print to file" feature so I can use its resize and sharpening capability. "Print to file" leaves an rgb file on my desktop which I then I print through QTR.  So if I have a grayscale and use "print to file" the new image is rgb.  No way around that.  I can convert the grayscale image to the QTR-Create_ICC file in QI when I use "print to file" but the results would be an rgb image on my desktop with an imbedded grayscale icc file.  That's where an RGB-QTR-Create_ICC version would be handy for me.

What I do now is take the rgb image back into Photoshop and covert back to grayscale before printing with QTR.

  The file has to be converted to the output profile prior to printing.  I
  don't use Qimage and noticed that subsequent posts are Qimage centric.  Can
  Qimage, while requiring an RGB image, not convert to a greyscale ICC profile
  at printing?  If not, surely Qimage could simply pass through the file pixel
  values to the printer (ie a Same as Source workflow).  Then, I think, one
  could converted the image to the QTR Create ICC output profile (greyscale),
  ASSIGN the RGB profile required by Qimage and then print Same as Source.
  Users of Qimage would have to judge if this is possible.
