NOTE:
The portion of the lesson discussing a computer imaging system
was developed using generic computer terminology that applies to
most imagery systems. The order and some steps in the process
could differ depending on the system you are using.

Computer Imaging Systems.
With the advancement of computer technology and graphic software
programs, computer imaging systems are now another tool that an
illustrator uses to produce graphics projects.
An advantage of a
computer imaging system is, no matter what the desired output, you can
design all projects in the same manner and then use the software for the
specific output (i.e., viewgraphs, 35mm slides, hard copy, etc.).
These systems are time-saving tools because once you have designed the
graphics, you print a hard copy, and save the image to the hard disk or
on floppy disk. If you are reviewing the graphic and you see the need to
make changes, you simply recall the graphic to memory, make only the
required changes, and repeat the process to print a hard copy and save
the graphic. Most graphics software programs provide a means of changing
many of the attributes of a graphic, such as, but not limited to, the
size and style of lettering, line weights, and backgrounds.
a. Inputs and Outputs. A typical graphic imaging system has many
different input and output peripherals that make up the system. The key
to a system that operates well in all modes is compatibility of the
software and peripherals. If the software cannot interface (communicate)
with the input or output devices, the results are unrecognizable symbols
and characters.
Figure 1-79 shows a typical graphics imagery workstation. The inputs for
this work station are the keyboard, mouse, and scanner. The outputs of
this workstation are the monitor, laser printer, plotter, and camera.
b. Creating a Graphic Using a Computer Imagery Workstation. Prior
to turning on the computer, review the VI work order for the job
requirements, and review the standing operating procedure (SOP) for any
standard formats already developed.
(The use of standardized formats
saves time and adds to the VI facility's professional reputation.)
After you have reviewed the work order, turn on the computer and perform
the necessary steps that the software requires to start the graphics
program that you have selected to produce the graphics (i.e., pie or bar
chart, text, illustrations, etc.).
Then, you enter the data for the
graphic from the thumbnail sketch provided with the work order, which may
include:
