Carbonless Paper | Uncoated
Paper | Carbon Interleaved Forms
A unit set is made up of two or more parts. The paper can be
the same on all parts or each part can be different. The number of parts and
type of paper will depend on the use of the form in the workflow process. The
imaging quality from part to part of the form will be affected by the number
of parts and the type of paper used for each part. Part to part imaging can
be accomplished in two ways:
- Carbonless stock, which has a coating of
special chemicals, can be used. The image is transferred through the parts
as the pressure of writing or typing instruments causes the chemical coatings
to react with one another, resulting in an image (see below).
- An uncoated stock, which is not coated with
any image producing chemicals, can also be used. An image is produced between
the parts by inserting carbon paper to make
a carbon interleaved form.
|
Note: Imaging from part to
part should not be a problem on 4 parts or less of a unit set made
up of standard weight papers. Forms that are over 4 part should be
tested for imaging quality.
|
Carbonless Paper
|
CB - Coated Back
|
The CB stock will transfer an image to the CFB stock
or to the CF stock.
|
|
CFB - Coated Front & Back
|
The CFB stock will transfer an image to another
CFB stock or to a CF stock.
|
|
CF - Coated Front
|
The CF stock does not transfer an image. It accepts
the image from the CB or CFB stock.
|
|
The imaging happens when the CB and
the CF chemical coatings react with each other, however, if you need
to prevent imaging in specific areas of a carbonless form, a desensitizing
ink is required.

Description
|
|
CB
|
20 lb. & 26 lb.
|
20 lb and 26 lb. papers are used when part 1 needs to be of a little
heavier weight for durability or when there is gong to be backprinting
on part 1. The heavier weight will help prevent the backer from showing
through to the front. The 26 lb. is also used for check applications.
20 lb. and 26 lb. are available in white.
|
|
CFB
|
17 lb.
|
17 lb. is used when the internal parts need to be
a little heavier than standard weights. White, canary, and pink are
readily available. Consult your manufacturer for the availability
of other colors.
|
|
CF
|
27 lb., 33 lb., 105 lb.
|
The 27 lb., 33 lb. and 105 lb. weights are used when the last part
needs to be extra durable because of handling or because of the type
of application in which it will be used. It may also be used to add
overall stability to the form. The 27 lb. and 33 lb. are available
in white and buff; 105 lb. is available in white and manila.
|
|
Note: There are other specialty carbonless
stocks available to you. Consult with your supplier for information
on the specialty papers and their availability.

|
20 lb. & 24 lb.
|
20 lb. and 24 lb. are used when part 1 needs to be of a little heavier
weight for durability or when heavy backprinting would show through
to the front of the form. The 24 lb. is also used for check applications.
The 20 lb. and 24 lb. are available in white, canary, pink, gold,
green, & blue. For other available colors, consult your supplier.
|
|
Ledger
|
28 lb., 32 lb., & 36 lb.
|
Ledger is used when the last part needs to be extra
durable because of handling or because of the application in which
it will be used. It may also be used to add overall stability to the
form. Ledger is available in white and buff.
|
|
Tag
|
100 lb. & 125 lb.
|
Tag is used when the last part needs to be extra
durable because of handling or because of the application in which
it will be used. It may also be used to add overall stability to the
form. Tag is available in white and manila. Some manufacturers may
have restrictions on running anything heavier than 100 lb. tag. If
you have an application which requires a heavier stock, you should
consult your manufacturer.
|
|
Note: Ledgers and tags should not be used
for part 1 or internal parts if imaging from part to part is necessary.
The heavier weight of these stocks will greatly reduce the quality
of the image transfer. If you feel it is necessary to use ledger or
tag stock for any part other than the last, you should request an
imaging test from your supplier.
|
|
Note: There are many options
for paper that could be used in a unit set. The preceding information
described the most common papers used on standard unit sets. If you
have a special request it is best to discuss it with your supplier
for availability.

Carbon Interleaved Forms
When your form needs to have an image transferred from part
to part but you are not using carbonless stock, then your form will need to
have carbon paper between the parts. The following are points to consider when
deciding whether or not to use carbon interleaved forms:
|
Blue - Blue carbon is generally used for
handwritten forms.
Black - Black carbon is generally used on forms that will be
typed on or imprinted by some other type of mechanical means.
|
- Carbon interleaved forms will give you a better image transfer on some forms.
- To prevent image transfer in specific areas of the form, you can use a stripe
or pattern carbon. Stripe and pattern carbons have the carbon coating applied
to the carbon tissue in selected areas. The uncoated areas of tissue will
prevent image transfer to the part below.
- Feather edge carbon is used when a carbon needs to be extracted from the
form before all parts are separated. It generally has a perforation at the
top to assist in extraction of the carbon. Feather edge carbon would be used
on a form that requires image transfer to all parts when information is first
entered on the form but that cannot have additional information, that is added
at a later time, transfer to one of the parts. After the initial information
is entered, the feather edge carbon is extracted from between the parts where
image transfer is to be prevented.
- Carbon interleaved forms are generally less expensive than carbonless forms
but they are not as clean or efficient for the end user to work with. Once
the form is torn apart, you must dispose of the carbon, whereas with carbonless
forms, you do not have the carbon paper.
