QTR-Quadtone RIP

Printing a grayscale tiff through QTR on a Epson R200 with.... OEM Epson  
inks.  With both curve boxes set to "NONE" i get what looks like a  
black-only print which is OK as far as it goes.. but selecting any of the  
curves gives intense blue/red colouration to the print.  I guess I should  
be using MIS black inkset or suchlike, from reading this group - is that  
true?  Is it not designed for using OEM inks?

Andy,

QTR can print with ANY ink you can fit into your printer.  The 
program basically tells each ink position how much ink to spray on 
the paper for a given lightness level, but it has no idea what inks 
you have in your printer.  So, it can work with the standard Epson 
OEM inks, a quad black inkset, or any variation you can think of.  

If the profile you used was designed for a quad inkset, you will 
definitely get weird colors with the OEM inks, because you're mixing 
apples with oranges.  So the key is to use a profile that was 
designed for a specific ink and paper combination, then use the paper 
and inkset that matches.

OK Lou, I understand that, thank you.  Here comes the obvious question:
How can I find profiles for use with QTR + R200 + OEM inks and different  
papers?  I Guess it's easier for me to buy paper to suit an existing  
profile?

I haven't looked at the most recent version, but a couple of months back the profiles for 
the 200 started with "GQ" which in the tutorial says they are for Media Street Quad black 
inks.

Hence it thinks it is printing with 4 (or more) blacks and you are feeding it CMYK etc.  This 
would make the colors weird!!!

You could learn to love them  :) a la surealist...  you could become famous for your new 
age vision of color (don't take this too seriously).

or get profiles for UC inks, or switch printers.

QTR does work great with UC inks, but need the right curves/profiles.

Andy,

QTR comes with some curves for each supported printer.  That's the 
first place to check.  You probably need to have QTR load the 
profiles for you printer when you load the program.

The second thing you can do is ask people on this forum and the DigBW 
Printing forum if they would be willing to share profiles.

The third thing you can do is build your own using the curve 
generation program in QTR.

I use IJC/OPM for my B&W work, and unfortunately the profiles are not 
compatible with QTR.

Hi Andy,

With the standard inks the R200 only has one black ink.  So you really
can't do much more than black-only printing.  This is essentially what you
saw with the no curves selected (although it's not linearized).   You can do
the same thing with the Epson driver.   The only significant way to use QTR
with the R200 is to use the Media Street QuadBlack inkset.  With this you can
make very nice matte or photo with gloss prints with a range of toning
capability.   You can read about it at www.mediastreet.com
