Reproducing Color Images as Duotones
Joanna L. Power, Brad S. West, Eric J. Stollnitz, and David H. Salesin
University of Washington
Examples
The example images described below are all simulations of the output that
a printing press would produce. The inserts provided with the printed
version of the SIGGRAPH proceedings show our actual results.
Example 1: Cezanne's "Blue Vase"
(a) [examp_1a.tif] process-color print
(b) [examp_1b.tif] traditional duotone using PANTONE 130 and Process Black
(c) [examp_1c.tif] our algorithm's duotone using the same inks
(d) [examp_1d.tif] black-enhanced duotone using PANTONE 198, PANTONE 604,
and Process Black
Example 2: Photograph of a koala
(a) [examp_2a.tif] process-color print
(b) [examp_2b.tif] duotone using PANTONE 144 and PANTONE 546
Example 3: Renoir's "Women"
(a) [examp_3a.tif] process-color print
(b) [examp_3b.tif] duotone using PANTONE 144 and PANTONE 546
(c) [examp_3c.tif] duotone using PANTONE 172 and PANTONE 354
Example 4: Photograph of a woman
(a) [examp_4a.tif] process-color print
(b) [examp_4b.tif] duotone using PANTONE 152 and PANTONE Process Blue
Example 5: Photograph of a girl
(a) [examp_5a.tif] process-color print
(b) [examp_5b.tif] duotone using PANTONE 152 and PANTONE Process Blue
Example 6: Photograph of three children
(a) [examp_6a.tif] process-color print
(b) [examp_6b.tif] duotone using PANTONE 152 and PANTONE Process Blue
Example 7: Photograph of a sunset
(a) [examp_7a.tif] process-color print
(b) [examp_7b.tif] duotone using PANTONE 151 and PANTONE 246, and Process
Black, corrected to match the process-color print
(c) [examp_7c.tif] duotone using the same inks but without correction in
order to obtain colors outside the gamut of process-
color printing
Example 8: Schiele's "Agony"
(a) [examp_8a.tif] process-color print
(b) [examp_8b.tif] duotone using PANTONE 329 and PANTONE Warm Red on
yellow paper
