Re: I made a print in QTR I think I did something wrong
Diane Fields
开云体育Just sent this to digitalb/w list
too.
?
Okay, Ann.? Hope this will
help.
?
First of all---the ICC profiles should be (for
windows) in the windows folder (should be available in your dropdown if it and
the other 2 ICC profiles--gray-matte and gray-photo--were placed in your
C/Windows/system 32/spool/drivers/color).? Process your print in PS,
convert to gray-LAB.? ?Now, you can softproof this by going to
view/proof setup/custom and in 'profile'?browse for the QTR-gray matte, set
your intent to 'perceptual' and check 'ink black'.? You will def. see a
difference--and it probably will be 'flatter' looking.? So--here's where
you can tweak--add an adjustment layer of curves perhaps, dodge and burn-- (new
layer/overlay check 18% gray and use your black and white brushes at about 7-9%
opacity) but as far as tonality/contrast, wysiwyg (what you see is what you
get)--but not as far as the 'color tone' though.
?
As far as the profiles, did you put them in
C/program/Quadtone RIP/profiles/2200-uc?? I think you are printing with a
2200 and OEM inks--not sure.? If so, this is where they should go and they
will show up in your dropdowns for your curves.

I made a print in QTR I think I did something wrong
I made a print in QTR..print looked good..a little warm..then I
re-read the instructions and saw I was supposed to first change the image in photoshop to grey scale from RGB. I did that and the print was terrible..flat no contrast.What did I do wrong? How am I supposed to use the grey space zip file which contains gray matte icc, gray photo icc, rgb lab icc...etc.? They were moved to the QTR folder. Also I downloaded the curves for various papers, extracted them into QTR, but I do not see them pop up in the GUI interface. What am I doing wrong. As always thanks for your support..Ann |

Re: The Advantages of QTR Are?
Diane Fields
开云体育Steve, the BIG advantage of using QTR over PS
is the lack of metamerism in monotones.? I've printed b/w or monotones for
years with first a 1280 and then my 2200.? I print from either PS or
Qimage.? I have been unhappy with metamerism from day one, however the
'alternatives' were pretty expensive (RIPs) or I just hadn't made the decision
to go with a dedicated printer yet.? When I bought my 2200 several years
ago I had strongly considered that path, but had procrastinated 'dealing with'
monotones by using duotones which helped a bit (not really--they just visually
diverted you a bit with toning).? I've subscriebed to the Digital b/w print
maillist off and on for a good while, and when I resubbed in late Winter I
discovered that there was a reasonably priced RIP available for Windows.? I
demoed it for several weeks and was sold on it.
?
So--that's my story LOL.? QTR prints
aren't subject to metamerism--my reason for printing with it.? I do all my
postprocessing in PS first, then bring a finished file to QTR, select my blend
for the paper I'm using and get excellent prints.? In the past I was using
Epson Velvet primarily for my matte prints, some Hahnemuhle Photorag.? I've
just done a series of step wedges on 11 different papers and have a good
reference point for other papers also.? I use Epson Premium Semigloss for
my non-matte prints.

The Advantages of QTR Are?
Steve
I'm a new member of the QTR community and fairly new to digital
b & w photography. I wanted to know what advantages are offered by this system versus others including Photoshop. I use an Epson 2200 printer and mostly print on Enhanced Matte and Premium Luster papers. I've also started using Ilford Smooth Pearl paper. Are there distinct advantages of using the QTR? I'd like to hear your opinions. Thanks! Steve |

Re: Dumb questions
Diane Fields
开云体育I'll let someone else explain the technical
aspects of a curve and an ICC profile, but for one thing--you cannot use a curve
in place of a profile.? An ICC profile is, for instance, the color space of
your monitor, the working space you use in PS, the paper profiles you choose for
printing (and then make sure your printer chooses 'no color adjustment').?
The curves are what QTR 'tells' the printer as to how to use what colors (what
nozzles to use).? There will be someone that can tell you much better
technically the differences--hopefully.?
?
If you using a PC, you will want to convert
your RGB image to Gray-LAB (which is an ICC profile--and should be in your
dropdown in PS).? Do any tweaking here (I won't go into softproofing here),
save this as a 'master' file in tiff.? Then--convert this file to
Gray-matte or Gray-photo (both ICC profiles--you will find these 3 in a zip on
the QTR download page--the RGB profiles are for use in Qimage)?depending
upon the paper you choose to use for printing.? Having the master in
gray-LAB allows you to go back and print easily on a matte or semigloss/gloss
paper.? You will choose the gray-matte or gray-photo tiff to use in
QTR.
?
Hope this helps.

Re: QuadTone RIP tutorial or FAQ
Diane Fields
开云体育1.? Ah--thanks.? I never had a
darkroom though I would have loved to in my film days--all I could think of with
a 'roundabout'was the auto 'roundabouts'--which I first encountered years ago in
Canada but we have some in NC now also..
2.--well, hadn't thought of LOL as 'lots of
luck' (sardonically) but I can see that--the way one would say it--exactly as
you suggest *smile*
3. The softproofing is working well for
me.? Lou's post helped a lot in what Roy had in mind.? I learned that
you could, prior to this, use 2 ICC profiles and an action that Carl had made to
'sort of ' proof blends--and in fact I still have that thanks to Carl, but for
tonality/contrast using Roy's LAB profile works pretty well for me with the
softproof/ink black.? Still--one has to 'envision' the curve (blends, if
you choose)?with it.? I did 12 papers with 21 step wedges in series
yesterday and today--and hopefully that will give me a good guide as to choices
of blending the curves with certain papers.

QuadTone RIP tutorial or FAQ
Diane, 1. Printing a "roundabout" is not a British practice but a technique used in printing color photos to assess color balance. I don't think anybody does that anymore with all the new technology.
2. LOL can also mean "Lots of Luck" in the sardonic sense. IMHO 3. I'll second your suggestion on a tutorial on "softproofing". I'm still not comfortable with that procedure. Ian From: "Diane Fields" <picnic@...> [Add to Address Book] [View Source] To: <QuadtoneRIP@...> Subject: [QuadtoneRIP] tutorial or FAQ Date: Sat, 2 Apr 2005 17:27:18 +0000 As I sit here and print step wedges on a variety of papers with my 2200/QTR, I've been thinking about the numerous posts on the Digital B/W list (where most people still seem to end up with questions about QTR) about 'how' to use QTR. In truth, the install and use on WinXP is pretty straightforward. I think what bumfuzzles a lot of people is the 'how' to actually use it. I believe many have curves and ICC profiles confused, and if they don't, they seem not to know where to begin to use the installed curves. It would be helpful if one of the more experienced users of QTR write a tutorial (one for Mac and Windows both would be helpful). I think what throws many is what curves to use---if you aren't using one of the papers listed (and now I'm not sure what installs with QTR and what I added with the Carl Schofield download--if you don't have it, try this ) you aren't sure what curve to use for what. Someone also suggested printing 'roundabouts' of step wedges--I'm guessing maybe this was a UK person since I've not heard that term before for this use but took it as printing a series of step wedges on the same paper with curves/blends. I started with 100% warm at the top, then I printed a 75 warm/25 cool , etc. until I reached 100% cool (I did six--a 100 warm, 75/25, 50/50, 40/60, 25/75, 100 cool). I've printed 10 matte papers thus far (I have accumulated a number of sample packs) and have some more to do. I will then do the same for my EPremsemi as well as a sepia/cool series. This certainly helps you to determine what blends work best for you on what paper. The other helpful thing would be for someone to write a straightforward tute for softproofing in PS for Windows. I have a nicely written post I found (by Lou Dina I think) that is quite good and with his okay could post it. I'm not sure everyone 'gets' how to softrproof using Roy's ICC profiles. Diane |

Re: QTR 'alternate' curves
Diane Fields
Shorthand for 'laughing out loud', but basically is a way to add some 'body language' (IMO) to posts that could be read in many ways. For those of us that have been around on the net for years and years, one forgets that not everyone knows all the acronyms, etc.

Glad you are 'getting it'. I'm in the middle of writing a post about the possibility of someone writing some tutorials or a FAQ for this forum. I think that many are just not sure where to begin--and esp. which curves to use for what---and how. I've printed 10 papers with series of step wedges and that certainly is helping me nail down which papers I'll use for what images. In the past I've been using Epson Velvet or Hahnemuhle PHotorag for b/w for the most part (at least as my matte paper) and they are still high on my list (though both have OBA--optical brighteners--and this seems to be something others on the Digital B/W list stay away from) but I'm really liking 2 of the new Innova papers.

Subject: [QuadtoneRIP] QTR 'alternate' curves
I haven't yet tried creating any curves for papers I have--mainly because I'm sampling and trying to make a decision on what paper(s) I will use with QTR.? I've done this before with papers for color images both on 1280 and 2200, but printing 21 step wedges on papers with QTR for sampling without specific curves for some papers has presented me with a question.
?
Carl Schofield on Digital B/W list just mentioned the use of some of the available curves for 'alternate' papers, but I wonder about others.
?
For instance,? I received the Innova sample pack and would love to know what others have used for the Photo FB, Soft Textured Art and Photo Smooth White Cotton.? I also printed sepia/cool on William Turner, but wonder about what curve others would use (bar using a custom).? There are some others--which I try to do a search on in forum, but we all know the problems with that.? I also try to find specs on the papers listed that I'm unfamiliar with and see if they are anywhere close to the paper I'm working with.
?
BTW--someone suggested that Concord Rag was lovely for sepia--I concur.? I found one piece left and did step wedges.? Not sure I would use this paper, but it is very nice for that purpose.

QTR and MacOSX 2.8 with Epson 2200
abqrich
Yesterday I downloaded QTR. Everything seems to be in the right
place. QTR appears in Print Center. The problem is that nothing happens when I press print. I don't even get an error message. The printer is connected via USB. It works fine using the standard driver. I have tried everything. I can't think of anything more to do. Any suggestions will be greatly appreciated. Richard Garnett |
