QTR-Quadtone RIP

All,

I finally have what I think to be some satisfactory curves to share. 
I have uploaded them to the files section.

It's late here, so rather than expound further I'll just paste a 
copy of the readme file. Enjoy, and send me any comments/questions!

R800/R1800 Hahnemuhle Fine Art Pearl Quadtone Rip Profiles
by Matt Chapin
mattchapin2@...
----------------------------------------------------------

Package Contents:
R800_F-A-Pearl_2880_cool_v10.quad
R800_F-A-Pearl_2880_warm_v10.quad

These Quadtone Rip profiles are for use with the following setup:

- R800 or R1800 printer
- Hahnemuhle Fine Art Pearl paper
- Stock Epson inks

- Quadtone Rip Settings:
  - Printing Model: QuadR800 or QuadR1800
  - Media Type: Premium Luster Photo Paper
  - Resolution: 2880 DPI
  - Dither Algorithm: Hybrid Floyd-Steinberg
  
These profiles use the Photo Black ink and gloss optimizer for 
optimum
print quality on Hahnemuhle Photo Rag.

To install, copy  the files "R800_F-A-Pearl_2880_v10.quad" and 
"R800_F-A-Pearl_2880_warm_v10.quad" to the directory 
C:\Program Files\QuadToneRIP\QuadTone\QuadR800  (or \Quad1800 if you 
prefer.)

In Quadtone Rip, select printing model QuadR800 or Quad1800 to make 
these 
profiles available.  They can be blended to suit your tonality 
preference.

These profiles are linearized using a Printfix Pro spectrophotometer.
The cool tone profile is visually adjusted to approximate the 
tonality of a
professionally made sample B+W print from the Epson Stylus Pro 
3800.  Not a
perfect match, but pretty darn close!

Because I made some modifications to the .quad files after they were 
output 
from the Curve Creation utility, I have not included the .qidf 
files.  These
modifications were necessary to ensure proper working of the Gloss 
Optimizer.

I may continue to tweak these profiles.  Watch this space for 
updates.

Enjoy and distribute freely.  Emphasis freely.  If you intend to 
include 
these files in the distribution package of any other software, prior
permission is required.

Matt,

this is just to thank you for your wonderful work. I did myself some 
curve for EEh Archival Matte with only acceptable results (blocking and 
blotching blacks) but your curves are really outstanding. Finally I get 
consistant and good B/W results with the R800.

Just two questions: Do you think this curve works with The Ilford 
Gallery Smooth Pearl paper? Got to try it. Would this curve work 
without Glop on Hahnemuehle FineArt Pearl?

Best regards,

Ignacio

Ignacio,

I just tried Matt's curves with the Smooth Pearl paper and they work
great!

Matt ............... Thanks for your work. I was getting frustrated
with my attempts

Gregg

Gregg, thank you for your feedback! Ilford may be more affordable than 
Hahnemuehle on the long run ...

Hi all,

I used Matt's curves and got very good tonality results.
I haven't blend the curves yet, just used one at a time at 100%.
I would like to ask, since I remain a bit confuesd on tha matter, do I
have to convert in PS to any QTR profile same as QTRGrayLab etc or
simply leave the image as 8bit grayscale tiff and just apply the curves?

And one more thing. By using the settings exactly as suggested by
Matt, I get a white horizontal banding, actually one white line 2mm
thick, 2cm inside the edge of A5 paper.
Anyone else encounterd the same problem?

Thanks for your feedback
Zissimos

Hi Zissimos,

You should not have to convert the image in Photoshop - I have 
gotten great results by just saving the image as a tiff file in 
Photoshop. Other settings don't seem to matter much - 8-bit and 16-
bit, "Real" greyscale and "RGB" greyscale (where R=G=B) work equally 
well.

I have not encountered the same problem as you are experiencing, 
though admittedly the smallest paper I've used is Letter size, which 
I understand is a bit larger than A5. - Are you using a PC or Mac? 
Which version of QTR are you using?

-Matt

Hi Matt, thank you for your reply.

The banding problem was solved after a head clean cycle. I'm still
curious about it, because I wasn't having the banding issue printing
without QTR. Anyway!

I'm pretty much amazed with the consistent results I'm getting with
your curves. After some test printing I found that the best blend
combination that works for me is gloss_cool and gloss_warm at
90%-80%-70% split toning.

Now the only thing I could wish, is to find similarly good curves for
F-A-P on the R2400.
Do you have the printer? Are you aware of any curves for this combo?
