The ability to produce all
halftones correctly is essential in
order to produce accurate
grayscale and color images. The
Officejet 4500 produced virtually
all halftones correctly for each
CYMK ink color in increments of
10% from 10 to 100% as seen in
the test chart to the left. It was
also able to produce virtually all
halftones correctly for orange,
green and blue. As seen in the
right of the image sample, the
system was easily able to produce
both negative and positive text
down to 4 pt. font size. Overall,
the image quality produced by the
Officejet 4500 is more than
sufficient for virtually all business
and consumer digital printing
applications.
COPY-MODE IMAGE QUALITY
(Best Mode)
In black copy mode, the Officejet 4500 reproduced crisp black text, and clear,
readable text down to 4 pt. font size. It was also able to reproduce clear lines as
thin as 3.2 lp/mm. (line pairs per millimeter) in both horizontal and vertical
orientations.
In black copy mode, the system was able to correctly produce the black halftone
scale in increments of 10%, as seen on the left, from 10 to approximately 90-
100%. While not apparent in the photo above (but visible in the printed image-
quality sample itself), the system was able to reproduce text in the black box at
the top. The system was also able to clearly reproduce text handwritten in pencil
and marker so that it is clearly legible.
