Appeal 2007-1544
Application 09/984,227
LeClair
5. LeClair teaches a method of producing a plurality of test prints
of a photographic image in which image processing parameters are varied
among the prints.
6. LeClair’s invention produces a plurality of reduced-size
versions of a full image, known as “thumbnail” images, each of which is
processed according to the varied image processing parameters (col. 2, ll.
43-55).
Henderson
7. Henderson teaches monitoring the overall print quality of a
printing system, by optically measuring the density of an area of a print
having a predetermined desired density (col. 1, ll. 6-16).
8. Henderson employs a plurality of densitometers, each
positioned to sample a different “swath” along a photoreceptor belt. A
sufficient number of densitometers may be employed so that the full width
of the photoreceptor belt may be covered (col. 4, l. 59 – col. 5, l. 3).
9. Henderson’s example image (Fig. 1) includes some solid-
density areas. As the image moves past the row of densitometers, one will
examine an area of a given size and of solid toner density, “much in the
manner of a deliberately-created test patch,” which happens to be already in
the image to be printed by the user (col. 5, ll. 11-24).
10. Henderson discloses that it is common, when desiring to
monitor the quality of prints, to artificially create a test patch of a
predetermined desired density (col. 1, ll. 12-14).
