R1800 profiles, magenta cast?

R1800 profiles, magenta cast?

2009-02-09 by winds310

I've profiled a number of papers for my R1800 with Epson ink after
buying the Spyder3Suite in January.  I'm using the 3.5PB2 software. 
For all of the papers, there is a slight magenta cast to soft proofs
and prints.  The good news is that the prints do pretty much match the
soft proof.  The tint is clearly seen in the front panel and seat of
the scooter in the test image, and in the sky and trees of the bottom
right test image.  Papers I've profiled are Epson Premium Luster,
Premium Glossy, Velvet Fine Art; Museo Silver Rag; and PremierArt
Platinum Rag, Smooth Fine Art, Velvet Fine Art.

If I apply the NeutralMinus preset, then all of the profiles are more
neutral, and are a much close match (soft proof on/off) to the test
image.  The prints also are more neutral, viewed under an Ott Light,
or daylight.  The monitor is a Samsung LCD, profiled with the
Spyder3Elite using 6500/2.2.

It just seems odd to me, that I get consistent profiles that are
slightly off.  It's easy enough to apply the NeutralMinus preset, but
it just doesn't seem like it should be necessary.

The differences you are describing would be fractional a* values,  
which are right at the border of what can be measured and controlled.  
And while neutral is the goal, a bit magenta is a whole lot more  
acceptable than even a tiny bit green, so the bias is to err on that  
side, if at all. You've found the balance that works for you, which is  
the important thing (and the reason I built that particular preset, as  
well; for many combinations it's just the right nudge).

Thanks for the response.

So it sounds like the combination of my particular printer and the
colorimeter.  My thought was, since it was consistent across all
papers, doing multiple readings and averaging them wasn't going to
help.  Seems that was correct.

A related issue, then.  Once I figured out to apply that preset, I
wanted to edit the measurement file information, so that I would have
a record of what I used (Tools -> Information).  But there is no way
to save the 'Advanced' profile adjustment settings.  It would also be
nice if that menu defaulted to the measurement file you are working on
in it's file selection drop down.  Better yet would be moving the
information function to the "Build Profile Setup" screen.
