QTR-Quadtone RIP

Many thanks to Roy Harrington for QuadToneRIP, it's excellent!
An to Paul Roark for the very useful info of his website.

When I bought my R265 I was very upset because I couldn't print in
black-only with the original driver.

But now with QuadToneRIP 2.5.2 I start to experiment, and I've just
created a simple curve for BO with the original black ink from EPSON.
I have a cheap Canon 646 scanner, uncalibrated, and it's unuseful in
the deep shadows so I tried to "guess" a curve using only ink limit
(18) and gamma (1.7).

I'm sure it's not perfectly linear, but my curve seems to work.
Here the curve for the Epson Premium Glossy:

http://www.andreaolivotto.com/test/R265/PremGlossyPP-BO.qidf

I printed many test images and gray scales, it is really no bad. The
tiny dots of R265 are visible only looking at less than 15cm.

Original ink from EPSON seems a bit warm and non metameric, just a bit
(nearly not visible) of green cast under neon lamp. The prints should
last very long, longer from the usual tests from the Wilhelm site
because I'm using only the black ink.

I'll appreciate any comment, and better if any volunteer will measure
it :-)))

No replies? No one is using R260/R265/R380 with QRT?

I just added another Claria BO profile for the Epson R380 (or 260) to  
the files section (in Curves>Epson R380 folder).  It uses Harman FB  
Al Glossy paper.  Good neutrality, no metamerism, smooth highlights  
but somewhat grainy midtones.  If you are printing images that don't  
have large, smooth midtone gray areas then the prints will look quite  
good.  Works well for busy landscapes and print surface looks exactly  
like an air dried F type silver print.

Hi Andrea,

There are also a number of black-only profiles made by Paul for MIS inks but
they will likely be pretty good for the Epson inks.  See the R260-MIS folder/
Printer Model.

Thanks Roy,

I have already taken seen those curves.
Do you think they will work with original Claria black as well?

Anyway, this way to print b&w is a good start for a novice like me,
cheap and ready to use. Next step will be grey inks, like MIS solution.

Many thanks again!

Thanks Carl for your contribution.

I just opened your curve and I see you made a linearization: how did
you do that? With an instrument?

Thanks!

Andrea

Yes, linearized with an eye-one spectrophotometer.
