Digital BW, The Print

Hi,

First off all, sorry about my english.

I posted this message at QuadTone Rip lis but nobody has patience to  
answer. I guess...

The truth is that it's a very good application with a hard learning  
curve and a lack off material to learn.

I'm trying to make my first QTR curve (neutral) just now and have:

Epson Enhanced Matte
Epson 9800 with original UltraChrome Inks and MK
Eye One

I Know some of you may be tired with beginner questions but it's
inevitable... I swear that i've tried to get all from Tom Moore
tutorial but I really can't.

Well, I've printed the first ink pattern calibration and found that
65% is the point where the MK Lab values (measure tool) reach it
maximum.

Printed the second, 65%, ink pattern and found that 100% LB = 24% MK
and 100% LLB = 35% LB . Ok?

My questions are:

1. am I in the right way?
2. Do I need to found relative densities for color inks? (I want a
neutral profile) if I need: what's the way ?
3. at Create Curve dialog Box what is "limit" and how I determine it?
4. What is the next step?

Thanks for the patience,

QTR is already set up to print on matte paper with the 9800 using the 
Epson K3 inks on download. You really don't need to create your own 
curves!


But, if you want to ....


> and 100% LLB = 35% LB . Ok?

You need to express LLK in terms of the MK, not LK

 
> 3. at Create Curve dialog Box what is "limit" and how I determine 
it?

The "Denisty" is what you have above, the maximum LK and LLK 
expressed in terms of where it falls on the MK step wedge.

The "Limit" is where you are no longer gaining desity on the LK and 
LLK ("L" values plateau.) Really the same as how you determined the 
MK limit in step 1, but you use the second step wedge.

Paul Roark has a good walk-through of how to create curves using QTR 
on his web site.

Do the 3 "K" inks first. Then look at your prints and see if they are 
too warm for you? Then you can look at possibly using the color inks 
as "Toner" inks (In QTR parlance in the channel drop-down.)

Best,
Michael
