DESCRIPTION OF CARBONLESS COPY PAPERS
Definition
Aerocopy
is a carbonless copy paper, coated with two different coatings.
When exposed to mechanical pressure it gives more copies
without using carbon paper.
Description
CB - first sheet (coated back):
|
Base
paper is coated on the back side with CB coating,
containing microencapsulated ink. Under mechanical
pressure microcapsules burst, the ink is released
and transfered to the CF coating which produces
a visible image. In a set of copies the CB sheet
is the original.
|
CFB - middle sheet (coated front and
back):
|
Base
paper is coated on both sides. Top side is coated
with CF coating, containing active mineral substances.
Bottom side is coated with CB coating. In a set
CFB sheets are placed between the first and the
last sheet; CF coating is always placed on the front
side and CB coating on the back side.
|
CF
- last sheet (coated front):
|
Base
paper is coated with CF coating on the front side.
The coating contains active mineral substances.
CF sheet is the last sheet in a set.
|
SC
|
SC
is a carbonless copying paper coated on top side
with SC coating which contains a combination of
CB and CF coating producing a visible copy as a
result of mechanical pressure.
|
SC-CB
|
SC
- CB is a carbonless copy paper:
front side is coated with SC coating, giving a visible
copy on front side when pressed mechanically
bottom side is coated with CB coating
|
Application of Aerocopy
carbonless copy paper
| Aerocopy
carbonless copy papers CB, CFB and CF are
used in a set which usually contains CB first sheet,
CFB middle sheets and CF last sheet.
Different
set combinations are possible:
CB + CF
CB + CFB + CF
CB + CFB (more copies) + CF
more copies of CFB
The
number of middle sheets depends on the required
number of copies. It is important to position the
sheets in the correct order when forming a set.
|
|
| SC
paper is used:
-
when typing without typewriter ribbon or if only
mechanical pressure is used
-
the first sheet is ordinary paper, only one copy
is needed |
|
| SC
- CB paper is used:
-
in similar cases as SC paper but when more copies
are needed |
 |
All Aerocopy papers can be used:
- as printed forms: continuous forms, sets, pads, etc.
- as unprinted forms: telex rolls, calculator rolls and
office paper in A4 or A3 size sheets
Number of copies
Aerocopy carbonless copy paper
of standard grammage gives the following number of copies
in a set: CB + more sheets of CFB + CF:
- handwriting (fibre tip pen, fountain pen): original +
0 copies
- handwriting (chemical pen): original + 3 to 4 copies
- typewriter: original + 4 to 6 copies
- electric typewriter: original + 7 to 8 copies
- matrix printer: original + 3 to 4 copies
- telex: original + 2 to 5 copies
The number of copies depends
on the type of typewriter, stroke and machine maintenance.
