QTR-Quadtone RIP

Hello

I wonder if QTR supports the 1290? How good an idea is it to try K6 
with this printer?

I imagine the K6 inks would work just fine in the 1290.  QTR supports the printer.
You would have to load your own cartridges and make your own profiles though.

Recent emails from Inkjet Mall indicate that preloaded carts for the 
1280 are do out soon.

Hello,

I need some guidance to improve my QTR curve creation.
I succeeded in making a nice, neutral tone, 21-step
tablet. I used K6 qidf file for the 7500 printer which
I changed to fit my R220 printer and inks.

Here are my MIS UT1 ink setup in the Curve Creator
with lot of guessing:

Printing Model - Quad 1200
Default Ink Limit - 70,  Black Boost  -  100

Ink Setup:

No Ink Limits

K - Gray Ink  - 100
C - Gray Ink  -  47
M - Toner     -  6,6   Blue
Y - Gray Ink  -  14
LC- Gray Ink  -  32
LM- Toner2    -  3,4  Light blue

Gray Curve:     10   10   Gamma 1
Toner Curve:    10   10   Gamma 1
Toner Curve2:   10   10   Gamma 1   

After the linearizing, I printed the final step
tablet.  The  tablet was flooded with the ink in the
100% area, it is neutral in tone, very even gradient.
Really, I am very proud that I, as a beginner, could
accomplish something like that. 50% density is 0,61,
but 100% is only 1,57. I don't like that, because,
when I printed through the QTR without the curve, I
got Dmax 1.68 on the same paper. I guess the toners
are diluting the ink in the 100% area. Your help here
would be very appreciated. 

Best regards,
Kemal

Hi Kemal.

Try lowering the black boost to less than 100%. Move it down
incrementally (say  to 75% or 50%) and see if it doesn't improve the
d'max somewhat. If you are truly flooding the 100% patch it can impact
drastically on density, actualy lowering it.

Regards
Duane
