There
are copy machines and then there are digital duplicators. While the
goal may be the same, both technologies use totally different
approaches. I am going to go into a few details on the benefits of each
technology. I’ll let you decide which technology is best for
you.
To
begin with, the supply used to actually print an image is completely
different. A copy machine uses toner to create images and text where a
digital duplicator uses ink to create an image.
Copy
Machines (Xerographic) – A copy machine uses an
electrostatically charged cylindrical drum to create images. A bright
lamp illuminates the document being copied. White areas of the paper are
then illuminated onto the drum. Areas of the drum that are not exposed
to light become negatively charged. The toner is positively charged,
sticking to the drum. The drum then transfers this image to paper, which
is then melted and bonded to the paper.
Digital
Duplicators – A digital duplicator also uses a drum as well
as a sheet of wax paper-like material called a master. As the document
is scanned, tiny holes are burned into the master, creating the image in
tiny dots. This master is then wrapped around the drum. Ink is placed
inside the drum. As the drum spins, ink seeps out of pores on the drum,
which then leak out of the tiny holes burned into the master. This
master then rolls over the paper, creating the image.
While these are
two fairly simplistic descriptions, you can see that the technologies
are very different. The reasons for using one technology over the other
varies, depending on what you will be doing.
With
digital duplicators, the initial cost of creating a new master costs
more than a copy machine, but the costs drops quickly as more copies are
made. Since ink costs so much less than toner, you pretty much break
even at about 25 copies. Everything after 25 copies then costs far less
than a toner-based copy machine.
Copies
on a toner-based copy machine (xerox-style) cost about 1.6 to 2 cents a
copy. This cost never goes down. Copies on a digital duplicator
initially cost slightly more, but with quantity (150 plus copies) the
price goes down to as much as 0.004 cents a copy. Also take into
consideration that copy machines make about 35 to 50 copies a minute,
where digital duplicators can create about 130 copies a minute.
Ultimately
if you plan on creating a few copies here and there, which is a lot of
us, a copy machine will cost less to operate. If you plan on creating
dozens to hundreds of copies of the same thing, a digital duplicator
will cost far less to operate.
