Re: OPM black banding

Re: OPM black banding

Antonis and Frank:

Antonis, I tested with black-only through the Epson driver.  No banding.  Is 
it possible to test a black-only profile through OPM without having IJC?

Frank, where are you with your Matte Black cartridge, level-wise?  Your 
description of the problem is good -- looks like thin scratches in black 
areas but not all black areas of an image.  I haven't had time to check with 
a densitometer, but I would bet that the black areas without bands are less 
than 100% black.  Under a loupe, the bands are actually a series of dots.  I 
have it throughout my 100% patch on a step wedge, nowhere else.  I have no 
banding with Epson or IP 5.

Helene, and Frank

I'll forward this to the people at Bowhaus and see what they say. Of course, 
you too can contact them directly  at: software@...

When I get a minute I'll upload a black-only profile for OPM.

Thanks, Antonis.  IJC/OPM is just too good not to pursue.  I will also 
contact bowhaus and get back to the list with any information I receive.

Re:OPM black banding

2003-04-03 by culturalvisions

After multiple head cleanings and finally a Matte Black cart 
change the banding seems to have disappeared.  I believe the 
OPM dependence on black ink simply pushed my cart to its limit.  

Antonis and other IJC pioneers:  I am looking forward to a little 
magenta in that cool profile.  Please let me know when the new 
cool is available.   And thanks again for the generosity of your 
efforts.

I spent the day comparing OPM with IP RIP on my 2200 and have 
found them to be very close.  I like the color of OPM blended 
80/20 warm/cool better than anything I can come up with on 
ImagePrint, but IP has a smoothness in the flesh tones that OPM 
can't match.  At least not without my using the IJC.

With Piezo on my 1160 added to the comparison, that quad 
technology is still the one to beat for b/w.  With the new Cone 
Epson driven inks in mind, I think I'll wait for the 2200 quads 
before buying the IJC.
