QTR-Quadtone RIP

Dear Group,

Please forgive me with the length of this post...

I would like to ask the group for some advice, since I have not used an Epson 7000 and K6 
inks in the past, and I would like to briefly discuss what my workflow is presently...

I am new to digital black and white photography, but I exhibited work in a few galleries 
over twenty years ago, presenting selenium toned prints at that time.  Now I have my 4X5 
black and white negatives drum scanned, and I am exploring the production of a fine art 
black and white print again.

That said, I currently have several images, where the images were originally printed on an 
Epson 9600 with UC inks, and using the latest ImagePrint RIP.  The gallery, representing 
me at the moment, told me to not submit any images with metamersim and, or possibly a 
coloured ink in the blacks, for esthetic and archival reasons.  They have their rules, so I 
must reprint a number of images... :)

All of my negatives were corrected to accomodate the Epson 9600, UC inks and ImagePrint 
RIP, where the Imageprint RIP has default setting of Gamma 2.2 at a specific print house in 
town.  This forced me to do the following with all of my images:

1.    open my image in Photoshop;
2.    assign a Gamma of 2.2, to darken the image;
3.    make all of my adjustments in that space;
4.    remove the assigned Gamma of 2.2;
5.    save the image;
6.    reopen the image;
7.    do not assign a Gamma of 2.2;
8.    make all of the required sizing, sharpening for the image;
9.    save the file, with those adjustments, for the print house;
10.   make the print.

Voila, the image came out exactly as displayed on my calibrated monitor.

Now I have several images, which are too light to be printed directly to any other printer 
that does not have a default setting of Gamma 2.2, unless I assign and imbed a Gamma 
2.2 into the image file.

Recently I found a print house, to accomodate the gallery's request, that produced 
exquisite images of mine, with the embedded Gamma 2.2, and that print house would be 
"Cirrus" in Portland.  They use an Epson 7600 and the Quad Tone Ink set, where the 
printed image is set for selenium toning and printed on Hahnemuhle 308.  Outstanding 
work from Phil Bard, and associates, just absolutely outstanding.

A few days ago, I ran across a lab in my home town that makes prints with an Epson 7000, 
K6 inks, and they use the "BW Pro 24, 2001" software to driver the printer.  Curiosity 
brought me in. They printed an image of mine, embedded with the Gamma 2.2 profile, 
and it printed too light, compared to the prints received from Cirrus.

So, the owner operator of the Epson 7000, wanted to adjust the curve of the image in 
Photoshop, and print it again.  I did not want that to happen, since I believe that any curve 
adjustment would affect the overall image in areas I did not anticipate to change.  We tried 
this approach anyway, and it did affect areas of the print I did not want adjusted.

Because of this preamble, and because I have several results from a few printers and 
different papers, I would like to know the following for the Epson 7000 and K6 inks:

1.  Is there another solution and, or updated software for this printer 
    and ink set, that would allow the use of imbedded information?

2.  Should I create another set of images, where the image would be 
    a straight through print?

3.  Is there an esoteric method that would be brilliant and simple?

The second point means reworking all of my images, and it is not an avenue that I 
contemplate enjoying.

But then again, I have "Cirrus and Phil Bard" as my primary source of printing.

Again, please forgive me, regarding the length of this post...

I'm just curious,

Most rips have a gamma adjusment. QTR has a gamma slider. For instance
you can set a + or - number and use it for all the work. Gamma
adjustments let you do a global lightening or darkening of the entire
file without altering your initial contrast situation. If indeed all
you need to do is lighten or darken that shouldn't be a problem. But
like you say, when you start making curves then you are altering the
look of the file. 

Actually I don't see why you can't leave the prints you have with this
new place doing K6 and ask them to MATCH this density (what ever their
technique). That should  be only a matter of making very small tests
of them all. You could even approve them before they were output. Or
just have a couple of them done first. That is what I would suggest to
a client. Fact is QTR on a 9600 and QTR on a 7000 with K6 are
different ways of rendering a file. If they can't do this for you then
send your files to Cirus.

Jim, Your image requirements 1-10 can be done with an action in PS,
requiring little time to fulfill. Your images, which have some color ink in
them are showing their colors when moved from light source to light source.
While that might be an issue with absolute color, it does not mean that the
image permanence is questioned. 

 

Rather than trying a curve adjustment, how about a level adjustment to place
the midpoint further down the scale. Or a different curve? All these would
be made with custom profiles from different machine and equipment. Was the
Home town lab ever able to come close? Or did they stop after one try? 

 

Your original files are not being damaged by the home town lab if you are
bringing them in on CD/DVD, so if they can adjust your files to match, why
not let them?

He's right. The ultrachome prints have very good longevity when doing
monochrome and with QTR you shouldn't be experiencing metamerism at
all. And, if the printer is linearized you shouldn't be seing color
content either.

If there is no gamma adjustment on their rip (hard to imagine) all you
 have to do is make a LEVELS ADJUSTMENT LAYER in Photoshop as he said,
do a test, and when satisfied drag that layer into all your files. It
sits on top as as seperate layer so you easily get back to where you
started and can finese it from there. This is actually something you
could do yourself if he will do a couple of small 5"x7" tests for you.
This is really a minor problem in the larger scheme of things.

I think you will like K6 it is very beautiful.

Gentleman,

Thank you for the quick replies...

The local print house, using the K6 inset and the 7000, asked me to come back to day to 
try again.  So, I will do that.

As for the metamerism issue, it is an issue with the gallery and, or their clients.  They 
don't want to see this, and they will not sell them if it is present.  The metamerism issue is 
present on Epson's Lustre Paper, and the print house that created the images, incorporates 
"ImagePrint RIP" software to produce the prints.  They do not use QTR.

I don't think I am alone with this issue of metamerism at a gallery.

I will try your Photoshop suggestions today with the local K6 printer, and see if I can add a 
correction level to the image.  They showed me a few of their shop samples, and I was 
impressed with the smoothness of the black and white tones from the K6 ink set.

Again, I do not know if the software that drives the K6 printer utilizes an early version of 
QTR, and I obviously do not know what it is capable of either, just yet.

I had prints made with the Epson 9800 and the K3 inks, to compare against.  Metamerism 
is not completely gone on the Lustre paper, but gloss differential became apparent.

That said, these issues seem to be minimized, once the image is under glass in a frame.

Thank you again for your suggestions, and I will let you know how today turns out.

Hi Jim,

I'm a little confused about all the combinations you've got.

You have:   "an Epson 7000, K6 inks, and they use the "BW Pro 24, 2001" 
software"
The K6 inks are very new, I don't think it's likely that the old BW Pro 
24 software can run these.
So either it's different inks or different software.  Or maybe they are 
doing it anyway and
that's why the prints are too light  (the K6 inks have more lighter 
inks than the old quad inks).

Metamerism is due to using a lot of color pigments in the prints.  If 
you see a lot of this
with the ImagePrint print quite possibly they are not using the B&W 
mode which solves
most of this.  (This would be the same as using QTR with the Epson 
inks).

You mention using Lustre paper several times.  With UltraChrome inks I 
think you will always
have some of the gloss differential problems unless you spray the 
prints afterward.
Lustre paper is not compatible with the K6 inks or the older piezotone 
quad inks.

The think the first thing to decide is what kind of paper you want.  If 
Lustre then the 7600
with IP or QTR, or the 9800 with K3 inks is the only way to go.  And if 
you have to get rid
of the gloss issue then spraying is needed.    If matte paper is OK 
(personally, I think its the best)
then the K6 route or a piezotone quad solution like Cirrus is what you 
want, unless you can
get the UltraChrome guys to load matte black ink.

The K6 inkset is very nice but you really need to have software that is 
geared for them.
QTR is a easy to set up and inexpensive way to do this.

After all that is settled you should be able to work up a fixed 
correction curve for the new printing
method.  QTR has some tools that allow you to do this using ICC 
profiles and the color
management system instead of Photoshop.
