QTR-Quadtone RIP

Hi!

I am starting my adventure with QTR - previously I have been used to printing my B&W using AWB (and before that the darkoom :)

My setup is as follows: Epson 4900, using OEM inks.

Mac OS 10.8.5 (macbook retina)

I have tried printing through photoshop and also the print tool. I have tried converting the source document to all sorts of formats - prophoto RGB, Adobe RGB and grayscale gamma 2.2.

I am printing on harman by hahnemuhle gloss baryta warmtone paper. In the quadtone print dialog I have configured the curve to be UCpk-hmgloss.neutral (only one curve no mixing). 2880 dpi, bi-diretional and photo black.

In photoshop I cannot use the QTR gray photo profile so I have used QTR Rgb photo paper profile.

Using the print tool I have tried printing using no color management and also application managed (here I was allowed to choose the QTR Gray photo paper profile).

All my prints look the same and consistently they all look way too dark. I am using a calibrated eizo coloredge 245W screen so I should be pretty well calibrated on the monitor side. It looks like a photoshop curve have been added pulling down the shadows considerably.

Am I doing something completely wrong? I dont have the HW yet to make my own linerizations, but I would assume that the UCpk hmgloss neutral should get pretty close out of the box? Or is this profile for the old harman papers (not the new harman by hahnemuhle)?

Appreciate any hints :)

Cheers!

Michael

Hi Michael,

I have just released a new version of QTR that I believe should fix this.

Download and install version 2.7.4.
