How
Carbonless Paper Works
|
|
|
To begin with, let’s take a
moment to understand what is meant by the term
“carbonless”. Before carbonless paper was
invented, multi-part forms consisted of sheets
of regular paper with jet black sheets of thin,
tissue-like carbon paper in between them – this
sort of form is often referred to as being
“carbon interleaved”. The user would write (or
impact print) on the front of the form, and the
pressure from the writing or printing would
cause the carbon between each sheet to image the
subsequent parts, basically transferring the
carbon from each carbon sheet to the piece of
paper beneath it. Though very common, these
forms could be extremely messy, often causing
users to get a lot of the black carbon on their
fingers, and on anything else they touched after
that. In addition, when the forms were done
being printed and the carbon sheets were removed
and thrown away, people could read whatever had
been printed on the forms by looking at the
discarded carbon paper, making security an issue
on certain types of forms. |

Then, in 1954, came carbonless
paper, which worked a little differently than
its carbon interleaved predecessor. Carbonless
paper works like this: the paper is coated with
two different types of chemicals, CF, or Coated
Front, and CB, or Coated Back. These chemicals
are held in tiny capsules, and are released when
the capsules are burst by the pressure from a
printer or a pen. When the CF and CB chemicals
react with one another, the CF chemicals darken,
causing an image to appear on the CF side of the
sheet. One easy way to tell that the CF and CB
chemicals are indeed different is that when you
write on a carbonless form, only the front of
each sheet images, but there is no image on the
back of any of the sheets. This image is
created, of course, without the use of the
carbon sheet, hence the term “carbonless paper.” |

The only real
difference between Traditional Carbonless Paper
and Laser Carbonless Paper is the chemicals in
the older kind are harmful to laser printers,
and can cause premature wear to the rollers,
drums and other printer components. Laser
Carbonless Paper, on the other hand, is designed
specifically for use in laser printers and
digital copiers, and its imaging capsules are
not solvent based and cause no damage to the
components of the printer. |
