Re: The Advantages of QTR Are?
|
Diane Fields
开云体育Steve, I'm a newbie too at QTR but maybe
because I've read the other list for several years (and have been printing b/w
for a good while, first with the 1280 and with the 2200) and am pretty familiar
with PS, the QTR workflow works for me.
?
No, QTR won't cure bronzing because that's a
function of the ink/paper combo.? If you notice on the Digital/bw list they
spray their prints to counter that problem.? The newer R800 and R1800, we
assume, will deal with the bronzing by using the Gloss Optimizer (and this is
the 'glop' they talk about on the other list--they are adding it into a cart to
use with the black inks--3rd party--like with the MIS inks and Paul Roark's
curves).
?
I don't know of a tutorial.? Did I send
you the post I found of Lou Dina's that explained how to softproof in
QTR?
?
What the step wedges help you with is
envisioning what those particular curves will look like on that particular
paper.? I laid out my 11 sheets with the step wedges on them and was able
to pick out the papers I liked, then I could see what a 75 warm and 25 cool
blend looked like, for instance, on that paper.? I like not quite
neutral--just a bit of warmth to it.? On different papers the curve blend I
might choose could be different--because the tone of the papers affects the
image a great deal.
?
When you open the QTR GUI in Windows and you
select the image file you want to print, then you have to choose a 'curve' for
it down below.? For instance, I want to print on Epson Velvet.? So--I
choose a matte paper in the paper dropdown.? I make the selections as to
dpi, etc. in all the other places.? Probably I would check 'centered' (but
if you are doing step wedge printing, you will keep dragging the step wedge file
around in the window to place it differently for different printing--if you
don't understand this, I can do a print screen and send it to you
offlist).? Now--you need to select your blend percentage (middle box) and
your curves.? Since I use Epson Enhanced matte as a proofing paper for
Velvet, I feel that those curves will be close enough for me for Epson
Velvet.? In the left curve drop down box, I choose EEnhMatte-Cool and in
the right box I choose EEnhmatte-Warm.? From my series of step wedges I did
on my Epson Velvet paper (I did 6 rather than do a long series of
percentages.? Once I establish for sure what papers I'm going to use all
the time, I will do a series of step wedges from 100% cool to 100% warm in 10%
increments) I find that a 60 cool/40 warm is about the blend I like on that
paper.? So--I move the blend slider over to?60 (the blend number
represents the amount of the curve on the left--the one for the cool).? I
did not adjust my ink limit for this paper (though I may in the future) so I
will not make any other slider adjustments for now.? Then---I'm ready to
click on print and that's it.
?
I addressed softproofing in the post to Anne
(Montauk lady).? It will help you correct any tonality/contrast issues with
your print--before you print (for the most part--its pretty difficult to get a
perfect reading on a monitor to match a paper print because of the difference in
the mediums).
?
I hope this is helpful.? I really think
printing the step wedges on the papers you use all the time will be a big
help--and I'll be glad to help you figure out how to do that.
