Digital BW, The Print

Hi!
Is it possible to do Prints on glossy paper with the MIS VM-Inks? 
I've read somewhere that the final Print has to be sprayed with 
something? Which spray is it? Does the PermaJet-Spray do the trick?
Regards
Peter

Yes, while MIS VM pigments are no "compatible" with RC/Glossy paper in that
they will not stick well by themselves, a fixative type spray can take care
of the problem.

I think most of the acrylic or lacquer sprays will probably work.

One difference with the new MIS Ultra Tone inks is that they will stick on
RC papers.

Paul,
can I replace the VM-Inks with the Ultratone-Inks when they are empty 
or do I run the risk of damaging the Printheads of my 1290? I've 
heard somewhere that once you've switched to a certain MIS Quadtone-
Set you should stick with this one. I also thought about replacing 
the VM-Set with the VMS-Set. Is it possible or do I have to buy a 
second printer for that?  
One last thing: When doing prints with your curves I sometime 
experience harsh black parts in the image. It's hard to describe, but 
it looks as if the parts with the black ink were solarized. Any 
solution for this issue? What about Tyler Boleys curves?
Sorry for the bunch of questions. Any help would be apprechiated.

Regards
Peter

Peter, I use UT inks and have had few problems with them on glossy 
papers, they only smudge when I apply alot of pressure!.  

Wrt the curves producing extreme tones. this may have something to do 
with a fairly well manipulated image before the curve is applied.  
Once you have applied the curve (if as a layer flatten the image) and 
then look at the histogram in levels and see what state the curve is 
in.  If there is a lot of info missing in the left-hand side the 
computer has to guess what tones should be there, hence the unreal 
tones.  The only way I have cured this posterization is to rescan the 
image, and make the scan look like I want it to wrt tones, contrast 
etc and then apply very small curves/levels to make sure the image is 
in good condition for when the curve is applied.

Peter,

I recommend that the cartridge parts of any CIS/CFS be changed if you use
one of those.

Other than that, the issue has been the Eboni black's sensitivity to dyes.
There is some dye in the VM black, but it does not appear to be enough to
cause problems in the heads of desktop printers.  (Large format printers
should probably flush their systems.)

I doubt there is enough dye in the vm-k to cause the parking pad problem I
had when going from dye to UT in a 1280.  I installed UT inks in my 1160
that had been running VM K for a long time and had no trouble.

>I also thought about replacing the VM-Set with the VMS-Set.

The vm-s inkset is compatible with the vm inks.  (With any luck, the UT-2
I'm working on will give you the full sepia to cold range.  It's for the
1280, but I suspect it'll work on the 1290.  I hope to get back to that
project very soon.)

Printing a 21-step test file might be able to show what the problem is.  I
believe there is one of those files in the Files section of this forum.  The
truth is that "canned" profiles or curves are written for one printer (or an
average of several), and no 2 printers are exactly the same.  In general,
they are usually close enough to allow reasonably good results, but some
printers are too far out on the ends of the bell curve of printer
performance to work well with the canned curves/profiles.  In almost all
cases, one can improve their prints by tweaking the curves slightly to
account for the printer differences.

> What about Tyler Boleys curves?

Because not all printers are the same, trying different curves is a good
idea.  Sometimes a printer works better with Tyler's, sometimes it's just
the opposite.  It never hurts to try a different curve, however.  I'd
recommend that you use the 21-step test file for comparisons.
