QTR-Quadtone RIP

Please excuse me for this very basic question.  I am using

an EPSON 2400 and  a MIS  K4 inkset and EEM paper. 

My first attempt at using the QuadTone RIP.   

My first attempt at printing using the Quatone Printing window was 
not bad after some trial and error.  I used the Northlight Images 
test pattern for adjustments.

I used the blend and shadow and midtone  adjustment to get a good 
print.

Using just these sliders does it create a  basic curve ( profile) or 
just send the output of the setting to the printer?.

If it does where does it store it.

Thanks

Hi Ed,

I'm not the biggest expert around here, but perhaps I can help you.

Personally I avoid using the shadow and midtone sliders. If you use 
them to match your the print to your screen, I'd rather make sure my 
screen is calibrated, my workflow is OK (e.g. make sure the image is 
converted to the Gray Lab space before sending it to QTR) and that 
the QTR curves are OK. If you use the sliders to modify your image, 
I'd rather do this in the image file itself. But the latter is 
personal preference. 

The blend slider I use very often though.

The latest setting of the sliders is stored, but (to my knowledge) 
nowhere a new curve is stored. That's one of the reasons I edit 
solely modify in the image file and not with the sliders.

I think I understand most of what you said.

I asume the Gray Lab space is any one of the Adobe CS2 gray profiles

I do convert all my images to gray prior to sending to the the 
printer.

Actually, it's not. Assuming you are on PC, you can find it under 
\program files\quadtonerip\icc.

On PC, you convert it prior to printing it with QTR. I'm not sure about 
the exact workflow on a Mac.
