Interleaved Forms
A continuous form can be one part or multiple 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 on 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 continuous form
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. 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.
|
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 these papers and their availability.

20 lb.
|
White, Canary, Pink, Gold, Green, & Blue
|
A majority of one part forms are printed
with 20 lb. because it is more durable than 15 lb. paper. The heavier
weight helps prevent backprinting from showing through to the front
of the form.

MICR
|
20 lb. & 24 lb.
|
20 lb. or 24 lb. is 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. 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 one of these
stocks for any part other than the last, you should request an imaging
test from your supplier.
|
Continuous Letterheads
Many continuous letterheads are manufactured with plain 20
lb. or 24 lb. bond paper. There are many other grades and weights of papers
used for letterheads such as Laids, Linens, some with 25% rag content, and some
with watermarks, to name a few.
|
Note: Many of the specialty papers available
for letterheads are expensive and require more lead time when ordering.
Consult your supplier for availability and price.
|
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 things to consider when
deciding whether or not to use carbon interleaved forms:
|
Black - The most common carbon color used
for continuous forms.
Blue - A carbon color occasionally used on continuous forms,
but not as often as black.
|
- 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.
- 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.
