Re: [Digital BW] Is a perfectly smooth tonal gradient possible on inkjet?

try putting a slight gaussian blur on it and bring it in via a layer mask if
that's possible.

Subject: [Digital BW] Is a perfectly smooth tonal gradient possible on
inkjet?


I'm using an Epson 9600 with UltraChrome inks (Matte black), Somerset
Velvet for Epson, and ColorBurst RIP (PC version).  I custom-built a
profile (DTP-41 with UV filter and Monaco Profiler Pro) to be used
specifically for black and white images, and have had great results.
The problem is that I have some images I need to print for a customer
that have a smooth gradient - basically a heavy dodge on the subject
matter to create a halo effect - that show some "breaks" in the
transitions.  When I print a gradient test image (created in
Photoshop) I can see them, albeit they are very slight, meaning it's
not an artifact from adjusting the file.  I've tried different
resolutions and screening algorhythms (lower quality is slightly
better, but still not perfect) to try and improve things, but I can't
completely get rid of it.  I've printed the test with no profile
applied, and it seems to be there in the linearization as well.  I
even tried some tests with no linearization or profile, and I get the
same problem.  Has anyone been able to print a super-smooth, perfect
tonal gradient with this (or any) inkjet printer?  Or am I always
going to have some slight rough spots?  Every other type of black and
white image I print looks beautiful... it's just these damned
gradients without any texture that give me fits.
