Digital BW, The Print

I have recently purchased some VT Blax inks (rebranded MIS, as they 
are part of the same company) and have run into some problems; they 
might be me expecting too much from the inkset but I will ask anyway.

It seems that some prints when I print them out are missing some 
tones, and this is causing almost polarisation of the image.  I have 
printed them out on an 1160 with a quad-tone VT Blax set and there 
doesn't seem to be a problem.

This is the frustrating part; when I do a nozzle check it is fairly 
good with only a couple of lines missing (1mm on maybe one of the six 
patterns), when I do the purge it is fine when I print out the images 
they are not correct.  I regularly clean with IPA and water cleaning 
cartridges. 

I have taken the printer back to Permajet to see if they can find 
fault and funnly old thing it worked fine!

Is there a problem with the file? I have posted a couple of 300dpi  
images at my site and would appreciate it if anyone with a 1270 with 
MIS/VT Blax could try printing them out and see if they cause any 
problems on their set up.

The images canbe found at

Many Thanks for any feedback/help I might get.

Where are you based?  You appear to have images of Bath/Wiltshire so 
I presume you're not too far from Permajet (Fotospeed in Corsham, not 
Nova in Northampton) for another visit.  Why not take your 1270 with 
the images on disc, attach the 1270 to John's Mac and show him the 
problem frist hand.  He is an extremely helpful guy.

If you do this, you'll probably have to take the 1270 drivers as 
well.  He only has 1160s and 1290s.

Done that and that was the frustrating part. The printer worked when 
I took it around there, although not completely.  I was wondering if 
anyone else could reproduce the faults on their 1270s as I want to 
rule out the problem with the images/workflow that I have before I go 
back to John with less hair than I left him with on Thursday!  I am 
close to giving up on the VT Blax, if I could get a neutral black 
using coloured inks I would.

Thanks

Gareth,

I don't think they are the same company.  Permajet appears to be a
re-seller.

It could be bad curves.  I'll send the "No color adjustment" 1270/870 curves
I have that usually work better than the older ones.

The nozzle check should be perfect, not just fairly good.

Good luck.

Paul, Many thanks for the files and help.  I have applied the no-
adjustment curve but to no avail.  I tried printing out the Avebury 
stones image but there was still the polarisation showing.  I ahave a 
feeling it has something to do with the image rather than the 
printing process.  

I just don't know what is wrong with the way the image is created 
that is causing the problem.  I have been wondering if the fact that 
some of the tones are missing isn't so much but rather that there is 
too much of one tone and therefore overloading the print with too 
much.

I would appreciate it if someone could produce a print on their 1270 
to see if it is a problem with the image.  I will try and hook up my 
flatbed to show what the final printed image looks like.

Thanks once gain, especially Paul.

I know its poor netiquette to reply yo your own post but you can't 
edit messages in this forum!!

Just uploaded some scans of prints which exhibit the problems I am 
talking about.
