Paul and P.J., - thank you for some helpful ideas!
P.J.,
That's an interesting idea. I see how this might happen in some cases.
Looking at this comparison of gamuts for R2880 and aRGB, I can see that
indeed, orange might be in the region that is covered by aRGB but
not by R2880.

That may explain why I am getting different color between different
printing scenarios. But it is still hard to believe that
in this case, that could be a culprit for the difference
between the font color and the photo colr.
Visually, I minimize the difference to the best of my ability.
Even if it is slightly off, and even if it ends up outside of the gamut of
the printer/paper, is it possible that "the image processing train" pushes
them apart THIS much.
I am actually guessing that there might be some type of a bug in LR in how
it handles conversion of the colors that are not in the gamut of the
paper: When printing directly, photo and text (font) are converted
differently. (Could it be that photo is assumed to be in aRGB, while the
font is not, or something like that?)
Paul,
Thanks for the suggestion to use soft-proofing.
I had not used it before in LR, and I just looked, - and indeed, those
colors are shown as beeing out of the paper/printer gamut.
As for the application vs. printer color management, - I suspect we are
talking about the same idea: it's more accurate if one uses the
printer's ICC profile for the specific paper. I see that I was rather
ambiguous in expressing that.

Sounds like you have a gamut problem, one or both of the colors are out of
gamut for your printer's inkset, and the direct print is at some point in
the image processing train pushing them further apart. Converting the
image to 8 bits first by saving as a jpeg is pushing them closer together.

Why are you not using application color management instead of printer
color management? It seems that would produce more accurate color
representation. Also...what does the image look like if you enable soft
proofing in LR? Do you note the same problem?
Are you using Epson paper or some other brand? Color accuracy should be
better using software color management and the icc profile that matches
the paper you're using.

I encounter some rather weird behavior in LR (5.7.1), and I am totally
puzzled by it.
I have a photograph that has primarily white and orange color in it.
In Print module, I added a text-based ID plate and a text-based watermark.
For both of those, I selected orange font colors that are visually very close
to that of the photo.
1. If I "Print to: File" (withing LR Print Module dialog), then all orange
colors in the resulting JPEG appear to be similar to each other,
and if I import that JPEG back into LR and print to Epson R2880, all the
colors are similar.
2. If I "Print to: Printer" right away, the text font color is _VERY_
different from the color of the photo itself.
JPEG and the initial file - appear to be in the same color (on the screen).
But if I print both to the same printer (and paper) with the same otherwise
settings (besides the id plate and the watermark), -
The print colors (between the printed photos in #1 and in #2) are different.
I suspect that something might be off in the calibration conversion, as the
JPEG is in RGB, while the DNG is in Adobe RGB (but even this is a big
surprise). But what is completely puzzling is why and how the colors of the
text and the photo are different when those are printed directly to the
printer.
Also, I see this difference is present in the "Preview" that shows up when it
is enabled in the printer (R2880) "set page" dialogue.
(I should point out that the colors in the preview have ALWAYS been royally
messed up (on both Windows computers that I used with this printer, WinXP and
Windows 7, and different versions of LR, from 1 or 2 to 5 [Win7 only]), when
printing from DNG files in Adobe RGB, but prints were coming out mostly
fine.)
In all these cases, I have the configurations set to disable color management
by the application and enable color control by the Printer driver Profile.
Any guess for this weirdness?
1. Why do text and photo of visibly similar colors come out differently in
print?
2. Why do the prints from an AdobeRGB DNG and from an RGB JPEG have different
colors?
Thank you,
Igor
