Digital BW, The Print

I have curves and recommended settings for the UT2, 1280, and Premium
Semigloss (PSG).  Until the curves are posted, feel free to contact me for
copies.

 

The curves use "Photo Paper" media setting, AdobeRGB, No Color Adjustment,
1440 (I've been using High Speed unchecked).  The curves have the letters
"PSG" in the names to identify the paper.

 

I have a neutral curve that, somewhat like the EEM curve, has only 3 points
in the midtones of the main red (cyan/cold ink) curve and green
(magenta/un-toned carbon ink) curve.  This should allow easy adjustment of
the 25%, 50% and 75% points to alter tones in those areas.  Unlike the EEM
curve, however, this curve required adjustment in the deep shadows to stop
them from blocking up.

 

I also have sepia tone curve and carbon tone curves ready.  The carbon tone
on PSG is quite warm (y - c = 0.17).

 

The sliders use a different media type setting - "Premium Glossy Photo
Paper."  (I suppose I could have written the curves with this setting, but
it blocks up more than the Photo Paper setting with "No Color Adjustment.")
With the driver set to Color Controls (sliders activated), and the sliders
all at 0, the inkset and PSG print a little dark (50% = 0.67 and the shadows
are a bit too dark) and 0.03 warm.  To correct for the darkness, try setting
the Brightness slider to +5.

 

For a neutral print, try Brightness +10, Contrast -3, Cyan +7, and Magenta
-7.

 

For a warm print (y - c = 0.05), try Brightness +10, Cyan -15, Magenta +10,
and Yellow +25.  Deep shadow detail can be improved slightly by setting
contrast to -2.

 

I've been getting a somewhat consistent 2.4 initial dmax this evening.  It
decreases as the ink "cures" (or whatever it's doing). With luck we should
be able to maintain a 2.2 after spraying, however - and that's not too
shabby.

 

Enjoy.
