Ok, can't figure it out, need help with photos

[Hollidark]

I've been using the same SP540 since mid 2006 and have worked thru, fixed or replaced every problem I've ever encountered, proudly. With the help of this forum of course. But this ongoing issue with photos is about to give me an aneurysm. I've read and tried what little I can find but nothing seems to work for me. See the pics. Doesn't matter what profile or material I use nor if run it thru adobe or corel, the shadows or dark areas print "weird". What you would think would be the darkest area of the print comes out grey at best. Am I missing something easy or is it like a Roland rep told me years back, "it's not a photo printer"? Note that my Epson 7600 24" that I use for screen separations does not have this issue. Thanks!

I've seen this before many times, and it's almost always in an area that is dark blue or a tone thereof...

From my experience and a bit of research the cause is, apparently, a combination of a level of GCR that has been applied to the image in conjuction with certain RIPs inability to properly rip the ink levels for those tones.

Is that a customer-supplied image? Perhaps they might have the original "un-tweaked" version that you could run a test with.

Are you running this in RGB, LAB, or CMYK? What is your rendering intent for raster images?

It's not a true black which is why it comes out grey.

This was a major problem for me in Onyx until I started using advanced ink limits and setting black ink compensation to 3 or 4.
So yes it's a RIP problem - not adding black to four colour shadows to increase density.

Looks like a profiling issue.

Actually. I know it's a profiling issue. Need to calibrate your computers and printer to be synchronized. I can print that image all day from versaworks on a roland with no issues.
