My ignorance is gonna show here but here goes. I have read all the 
posts on the list and others and I don't understand. Why not use 
duotone printing with color inks, like a selenium-type tone? My eyes 
aren't the best but I don't notice any metamerism using this method. 
The prints look fine and if you were in a darkroom most people would 
use a selenium-tone for archival purposes. I may very well be missing 
something and if I am chalk it up to stupidity or inexperience on my 
part.

Tim,

You're not missing anything. I believe you said you are using a 1280 with
Epson dye inks?  I have seen little or no metamerism with Epson dye inks.

When you print a duotone from an Epson archival pigment printer you use 6
inks to reproduce the duotone (or tri or quad) that you created in
Photoshop. In my experience all duotones produced from Epson pigment inks
suffer some degree of metamerism... others have had better luck I'm told.

If you could print using two inks (a true duotone from a press) then maybe
this would help??  I don't find metamerism with the Epson pigment black so
am wondering which or how many of the inks actually contribute to it.

Tim, I just printed some black and white prints today, using the MIS
color inkset and the Torchon Profile I had made for the printer. (1160) 
On Torchon, Epson Archival and Eclipse paper, this profile works very
well indeed. No color cross overs, and a very close to neutral tone. I
was absolutely amazed to get consistent black and white prints from the
MIS color inkset. 

There are a couple ways to go, each offering a tiny different color
tone. One is printing from an RGB file, and the other from a Grayscale
file, both using the entire set of inks.  The nicest tone was from the
grayscale file. Almost identical to the quality you can get with the MIS
VM inksets on these papers. I'm going to put a print in the south window
tomorrow and see how the changes occur over the next couple months. Of
course you don't have the option for warm and cool prints with the
grayscale file, but you would with the color file.

Haven't tried duotone prints with this setup yet, but I will tomorrow
when the light is good.

Hi Jerry,

 Thank you, I will be very interested in how you make out with the 
duotone as well as your test. As you know, I am very interested in 
selenium-toned prints using color inks. With your experience in 
printing this is going to be very interesting. I am looking forward 
to your report.

How about metamerism, Jerry? Using profiles, I've had no 
trouble getting good grayscale prints using color inksets. But 
such prints have the reputation for being  either impermanent 
(like the Epson OEM dyes) or metameric (like the Epson and 
Generations pigments). The reported exception has been  
Cone's Color Piezo, which has poor blacks...

Re: [Digital BW] re:metamerism and b/w inks

Yup, Metamerism raised it's ugly head last night with the MIS color
inkset and black and white prints. Too much to accept, toward the red,
I'm afraid. A Real Pity.

Oh well, back the the VM MIS inks....

Hi Jery,

Thanks for your test on the MIS color inks in a duotone mode. I guess 
that tears it for me. I am going to stay with the Epson OEM inks 
until there are inks that will do what I want. I like selenium-toned 
pictures and will wait for Cones selenium inks and see what they are 
like. Thanks again.

Tim

Re: [Digital BW] re:metamerism and b/w inks

2001-09-11 by Jerry Olson

Evening Tim,

Well, I've been doing a VERY odd thing for me today. I have a display of
15 photos going up in a new gallery in town. They wanted Sepiatone
prints! After all I've gone through to get the cold tones. But these
Prints I've been printing today, aren't "Piezo Brown". They are
genuinely a very attractive sepia tone, and I was dumbfounded as to how
good they look. They are much richer in tone than the cold tone prints,
and the blacks are deeper. (Browns?) Richer, and more luxurious looking,
anyhow!!) They were printed with a color balance setting I made in
photoshop, and were printed with the COLOR MIS Archival pigmented inks.
They actually look more classy than the cold tones I've been printing
for all these months. They work on Eclipse and Somerset Enhanced paper
beautifully. I have never seen a monotone print on Somerset velvet
enhanced of this quality. The blacks? Browns? are deeper than you can
get with cool tones on this paper. 

So I would say yes, you can print any selenium tone you would ever want
from this inkset. The prints I've been printing today don't seem to have
any noticeable metamerism; This must be because any metamerism with this
inkset tends to be a little bit red. (About 6 or 7 ccs of red, if you go
by the kodak Gelatin filters.

Again, I learn something new every day. i never thought I would actually
like brown tones. But again, this is NOT an ugly piezo brown color, it
is a really nice color!

Tomorrow, I'll try and print a Selenium toned print for you and see how
the metamerism goes. It is different, depending on the file and it's
color/or grayscale mode. It is different if you print it from an RGB
image or from a Grayscale image.  So MANY variations are possible.  

Every paper I've used on these sepia prints print the images very well.
The only thing that does NOT look nice as this color is, of course, snow
scenes. They must be cool.

I really think if you put some testing time in with this inkset, you are
going to be very happy.

Jerry

I just can't believe what happened in New York and Washington today.
I've been glued to the news channels all day. I hope they will discover
exactly who is behind this and eliminate them utterly.

Take Care.

Hi,
I know you said these sepia toned prints exhibited no metamerism, did you 
bring them outdoors? I am looking for an archival inkset to make prints 
(sepia toned) which will be sold outdoors at art and craft fairs, but which 
will hang indoors, of course. Epson's 5500 made gorgeous sepia prints which 
turned puke green outdoors.
Thank you

Hi Jerry,

 Congratulations on your exhibit. Your images are great and I'm sure 
they will be very well received by the public.
 My family and I always say Grace at meal times and we included a 
special prayer for everyone involved in yesterday's terrible events. 
This doesn't sound very Christian-like but I hope you send those 
bastards to HELL when you catch them.
 I hope, I hope, I hope that you can get a selenium-toned print from 
that inkset. The only thing that keeps me from tearing my hair out 
(both of them) is that I have the OEM inkset which gives me good 
duotones. IMAGINE, JERRY OLSON printing sepia-toned prints and as 
Maxwell Smart would say AND LOVING IT :-). Jerry, they almost sound 
like they are a platinum-tone with the rich blacks and all. Thanks 
again, Jerry, for trying to help. I really appreciate it.

Best regards always,

Tim

Jerry,

I am very interested in your use of the MIS archival color inks to 
obtain good sepia-toned prints. What settings do you use in Photoshop 
6 and in the Epson driver? Do you start with scanned B&W negatives or 
color negatives?

2 Cyan, 10 Magenta and 20 yellow should get you really close (in
photoshop color balance.)

What you start with is immaterial.

Epson Driver:  

Photo inkjet quality media setting
error diffusion ON
High speed OFF
I'm using my torchon /epson profile, but you can start with the generic
RGB profile and tweak from there. Use Perceptual Rendering intent. I use
no color adjustment, because I'm using a profile.

Sepia tones aren't nearly as critical as black and white prints.

Works on most any coated paper. (slightly different sepia colors.)

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
