Hello Ernst,
Thanks for the comments.
I have been kind of thinking along your line of reasoning, i.e. higher ink load. To for stall the concern of paper/ink mismatch I print only on papers compatible with the PK ink on this machine, so I don’t think it is an ink paper mismatch.
Let me add a second part to the puzzle, which I neglected to point out before, but now after Ernst’s prompting seems appropriate. I edit on one machine and transfer the files to a laptop which I use to drive the printer with, which is at another site. As best as I can tell, I am pretty sure all the paper profiles on both machines are the same and latest incarnations. The one thing here is that the laptop uses PS CS4 as opposed to CS6 on my main work machine, could this be an issue? Am I correct in my understanding that color management is supposed to help control color reproduction problems in cross platform situations like this?
Here is the final quirk I’ve noted, as I operate more or less in a vacuum i.e. no formal training and no experience outside of what I have discovered on my own, can anyone tell me if printing from a windows CS4 platform normally pops the print driver/setup dialogue twice? Which I suspicion may be the culprit in all this.
So let me step you through this,
1 open print file (CS4 laptop)
2 select print from PS File menu
3 select all necessary settings including PS manages color making sure printer color management is off, black point is on and I have selected the correct paper profile, correct paper type, etc., etc. Hit print and off things go, well sort of.
Here is the thing that I don’t know/understand if it is standard behavior in a Windows/CS4 environment for PS/Epson print drivers or which could be the root my issue. As soon as I hit print in previous step (3) I get the basically same dialogue popup asking for all the same info again. I check everything a second time and hit print, and now it actually proceeds to print. Is this one of those are you “really sure” you what to do it this way sort of software “features” peculiar to CS4, or is this something that could be the root of my sometimes issue, i.e. a double profile, but that only seems to effect the black ink and only sometimes?
Could this be where I seem to sometimes get what seems a double dose of black ink?
Further I just checked on my main work unit printing from CS6 doing a test printing to the 9880 as a null printer, and I don’t get this same two-step hokey pokey on it? Curious’er and curious’er!
Well I suppose now that I actually have some free time I should actually go make some prints that I can collect a check for, instead of trying to scratch this small annoying intellectual itch, which in the main seems of little practical significance.
