Digital BW, The Print

Paul, 

I am using MIS VM ink cartridges on a 1290 printer with your curves.  
I note from recent postings that you have some reservations re the 
1290 and UT2 inks and I would therefore be grateful if you would 
provide advice as follows:

Does this same inconsistency of print occur with the VM inks?

What advice do you have for switching to UT2 inks at this time?

Can the Ebony Black be used with existing VM `grey' inks, if so are 
there any adverse effects?

Many thanks for all of your hard work developing these inks.

Regards

Garry Bisshopp

No.  There are specific 1290 VM curves.  However, the 1280 VM curves did not
work on the 1280.  So, I noticed the differences there also, but just wrote
different curves.  

>What advice do you have for switching to UT2 inks at this time?

As you can see from posts here, there are a number of people who are happy
with 1290 and UT2 inks.  They are printing darker than my targets, however,
and some of the differences might cause posterization with some curves.

>Can the Ebony Black be used with existing VM `grey' inks, if so are

I think that is what MIS is selling with the VM inks these days.

I am having problems with a new set of MIS VM cartridges on a 1290 
printer.  I have been using the MIS VM inks for some time and have 
been very happy with the prints.  I recently purchased some new 
cartridges (two diferent batches) but when I installed one of them 
the prints came out with a magenta hue.  I use Paul's EAM nc1 curves 
and print on Epson archival Matt paper, nothing had changed in my 
workflow except for the new cart. I have tried using all PR curves 
for both EAM and RAG and the cool and neutral prints all have the 
magenta cast.

A `purge' pattern print shows a distinct magenta hue in both the blue 
and light blue inks when compared with the previous carts and they do 
not match the swab colours on the MIS web site.


I tried a cartridge from the second batch and the tints were the 
same.  I then tried the carts on my second 1290 and again the tints 
had the magenta hue.  I repeated the tests using both Picture Window 
and Photoshop Elements with the same result.

I have removed and reinstalled the Epson printer driver but still 
have the problem.

I have e-mailed MIS and have sent them examples of prints but they 
cannot explain the problem.

Has anyone had similar problems?

Paul, have you any suggestions?

Garry,

It sounds like an ink problem.  MIS will have to take a look.

Frankly, ever since I started looking closely at inks, I've been surprised
by what seems to me to be a lack of consistency.  To match the MIS VM inkset
to my previous Piezo variable tone mix, I received samples of Piezo ink from
about a dozen sources.  Some were so far off I didn't even include them in
the average that I used for my target densities.

Ink consistency is a problem.  That may be what is going on here, and it
might have nothing to do with an MIS mixing error.  I believe MIS assumes
what it receives from its supplier is consistent.  I fear this may not be
the case.

I've had the exact same problem with the VM cartridges on my 1280 
printer when printing in the neutral cold mode (I hope that's the 
right label, it's not the cold mode nor is it the two warm modes, 
it's the mode that's supposed to give basic black and white prints). 
I used to get very neutral black and white prints with my 1160 and 
maybe when I first got the 1280, I don't remember exactly when the 
problem started, but lately I've had to print everything in moderate 
warm mode because of this problem. I've been intending to call MIS 
about it but just haven't had the time lately.

Paul,

Many thanks for you reply.  The information is very interesting.

I have e-mailed MIS but as yet have not had a reply. I will be 
returning the cartridges and have asked for replacements.

Best regards
