QTR-Quadtone RIP

I posted this message originally under Help!HORRID R1800 printing and
since then I've done a bit more troubleshooting.

After changing out all of the software options, I decided to go back
to Epson inks.  I printed using the Epson Quad1800 rather than the
QuadR1800-K7 printing model and the print came out fine.

I know that the K7 print model won't look right using standard Epson
UC inks, but I printed anyway just to see the result.    The
conclusion I am coming to is that the Blue channel is getting
massively overdriven when using the K7 print model.  People's faces
and what is supposed to be a white/very light grey background is
printed as blue/bluish-purple.  Maybe a mix of blue/magenta being
overdriven.

Does anyone have any ideas?  Have I set up something wrong in the
Epson driver that causes the K7 profile to not work?

One other clue is that when I look in the \Quadtone\Profile directory,
I do not see any subdirectory for R1800 K7 profiles, only R1800-uc,
which makes me wonder where QTR is picking up the k7 profiles that I
am selecting from.

Again, any help would be greatly appreciated.

Regards,

Mike Hill

Not all inking profiles (.quad files the ones used by QTR for actual 
printing) located in the Quad directory are editable, that is, they 
don't have corresponding .qidf files stored in the Profiles 
directory.  The profiles that are listed in the Curve Setup drop 
down are the Quad profiles.

K7 is a bw inkset so you should not get any blues.  It took quite a 
while on my R1800 to flush out all the old original R1800 inks (for 
me it was the blue and red that took the longest to flush).

Jeff - 

Thanks for the reply.  I took out the K7 inks and put standard epson inks back in to trouble shoot the situation.  I know the blues are coming from having 'colored' inks in them, but when I put the K7 inkset in and use QTR all of the light tones are completely washed over, creating a very muddy look.  I know the flushing isn't the issue because I've had the K7s in for several weeks of good printing before all of this started.

If you have any other ideas/experiences, I'd appreciate any thoughts.

Regards,

Mike

OK, To recap, you were getting good prints using the K7 inkset 
printing through QTR using one of the "canned" profiles (.quad files) 
installed with the QTR installation and all of a sudden you started to 
get muddled prints. Correct?

If you are printing using QTR, the Epson driver is totally out of the 
loop -- so all settings there are ignored.

Correct.  I used a canned K7 profile with the R1800-K7 printer model.

If the QTR profile worked fine initially as you indicated and now does 
not work it is very likely not the profile or QTR's problem unless 
something changed the profile (.quad file) or some setting in QTR is 
different. Did anything in your setup or workflow change?  Have you 
cleaned the underside of the print head and run one or two head 
cleaning cycles?  Is the parking pad relatively clean?

Also FYI, the three R1800-uc editable profiles (black, sepia, and cool) 
included in the QTR installation only use the mK ink for black or mK 
and Y&R for sepia or mK and M&C for cool.  The pK ink is not used. I 
haven't tried to profile my R1800 with the uc inkset using both 
blacks.  The pK will be a little less dense and thus offer a little 
more smoothness in the mid and highlights.  I use Paul Roark's 4K+Ccm 
inkset

Jeff - 

Thanks for the help, but I think I stumbled onto the problem.  This morning I removed the Epson colored ink and put the Niagra CIS back in to make another round of prints for you and Roy Harrington (I also received an email from him).  The print that I've been speaking of, that was coming out all muddy, printed just fine.  I could scan and send it to you, if you like, but it is a dramatic difference.  All I did was remove the epson inks and replace them with the CIS.  

One of the problems I've been having with Vista is that the software that monitors the Epson cartridge ink levels won't work under Vista.  Anyway, I am wondering if by putting Epson cartridges back in, it reset the chip status of the ink cartridges, which was affecting the print out.  I've read a couple of posts about buying a chip resetter, so I wonder if this has been the problem, because I certainly have run enough ink through the system for it to think that some cartridges were empty -- if that is the problem.

What do you think?

Thanks for the help.

I the ink status is stored in the individual chips of each cart, so 
that likely is not the problem.
