Re: help needed in creating unusual curve

2008-04-25 by David

Thanks again Duane.  

Yes, I see the check-off now. Another question: when I hit the "create
curve" button found in the Curve Creation tool, it brings up a
graphic, scaled 0-100 going both up/down and across, with lines
plotted for the ink colors. What is this showing me? 

Regarding the gentlemen's email, I know that this should be easier,
but there are issues with using the Epson R2400 printer with its
default driver for this task: 1) the black inks have trouble blocking
UV light; 2) the printer has no true "black only" mode; 3)I can't get
it to print at a lower DPI (ideally 360 or 720 DPI) to get the
dot/grain pattern I need; and 4) the matte black ink has higher
opacity, but by itself doesn't adhere well to most quality
transparency films.

So, I'm using QTR to both control the inks and the printer resolution. 

Yes, I've been fooling at this for far to long, and if I don't get
results soon, I may have to break down and buy a second printer such
as the Epson 3000, which does a much better job at this. 

Best, David
