A Brief Look at the 7470 Plotter
The HP 7470 Graphics Plotter is a vector plotter which produces high
quality, multicolor graphics plots on two sizes of drawing media:
English ANSI A (81/2X 11 in.) or metric ISO A4 (210 X 297 mm). With
programmable pen velocity and a choice of standard fiber tip or trans­
parency pens, the 7470 can produce distinctive graphics not only on
standard paper, but also on other media such as transparency film.
The plotter offers both fast plotting speed and high line quality,
achieved using Hewlett—Packard'smicro-grip drive technology. This
technology provides low—inertiagrit—coveredwheels to move the paper
in one axis while the pen moves along the other axis. Plotting occurs
with approximately 2 g acceleration and a maximum velocity of 38.1
cm/s (15in./ s). The result is exceptional line and character quality and
high throughput. The 7470 has addressable resolution of 0.025 mm
(0.001in.) and repeatability of 0.10 mm (0.004in.) for any given pen.
The multicolor graphics capability is provided by programmed or front­
panel selection of two pens. If additional colors are desired, the pro­
gram can be paused to allow manual installation of additional pens.
Seven different dashed—linefonts and symbol mode plotting provide
additional trace identification capabilities.
Character plotting speed of up to six characters per second enables you
to produce fully—lettered graphs quickly. Annotation can be easily done
using any of five character sets, including three European sets. Text
can be written in any direction, with or without character slant, and in
varying sizes. '
The 7470 is engineered to be especially useful in the areas of business
graphics, statistics, medicine, numerical control, surveying, and engi­
neering design. An optional overhead transparency kit enables you to
produce high quality graphic transparencies from your plotting pro­
grams. For faster comprehension, you can present economic trends,
engineering or scientific data, marketing plans, profit data, or sales
forecasts pictorially. And with a choice of media, you can create paper
hardcopy for an individual's attention or transparencies for group
presentations.
Whether data are tabulated, measured, or computed, depend on the
reliable 7470 to prepare multicolored plots of excellent line quality and
high resolution.
