Hey Dana or Jon,
Any idea why there appears to be a yellowish / warmish tone in the first few steps (.09, .17 & .21) of the density print? (still cannot upload or attach image… still getting “Error 2038”… so uploaded it to public dropbox at http://dl.dropbox.com/u/15782478/Inkjetmall%20Forum%20Image/21%20step%20wn-sel%20density%20print%20type%205.JPG )
The profile used for this was K7-3880-MPS-Type5. I’m using a split tone of WN1,2,3 and SEL4,5,6,7 inks on Cone Type 5 paper with a GO layer.
I profiled the density print with a B&W densitometer. It looks fairly linear to me.
I substantially flushed this Pro 3880 printer with piezoflush before installing the WN & SEL inks (the printer previously had Epson inks in it). I ran at least ten power clean cycles with piezoflush. It took a lot of flush… I had to dump the maintenance cart twice. I ran numerous WN/SEL test prints after the flush. I know that SEL7 is in what used to be the Y cart slot, but with all of the flush and SEL7 ink run through it, there should not be any Y left in the line or head. I don’t see any hint of Y in the nozzle checks.
So, I’m puzzled. I had expected (and wanted) to see a nice SEL gradient throughout the lighter shades of the profile.
