Copiers
Introduction
DMs interface with copiers daily. Copiers offer a selection of timesaving
options and provide good resolution reproductions. As copiers become more
sophisticated, they assume a more versatile and valuable role in the creative
process.
Copier needs
Volume range
and speed
Command or shop needs determine the type of copier purchased or leased.
Copiers are classified by volume range and speed. The command or shop
may need a color copier or a black-and-white copier. Available options also
influence the choice of a copier.
A low-volume range indicates the need for a personal copier which tends to
be slow in operation. A medium-range copier is for moderate use, and a
high-volume range indicates a heavy use, multifunction, high-speed copier
found in reprographic departments and printshops.
Standard
copiers
Standard copiers produce basic black images on either white or colored
paper. These images appear through electrostatic, thermographic, or digital
technology. Speed, resolution, and volume are the primary variables that
influence the selection of a standard copier.
Color copiers
Color copiers make the image appear through thermal fusion or laser
technology.
THERMAL: A copier scans an image at 300 dots per inch (DPI) and prints
through a ribbon that converts the image into a combination of four colors.
Heat transfers and fixes the image to paper.
LASER: Laser copiers use color toner instead of ribbon to create an image.
The color toner is available in cyan, magenta, yellow, and black. They use
digital technology to act as a laser printer, reproducing the image in very
high resolution.
