S & R Printing Types of Folds |
|
Half Fold
is commonly used for brochures and greetings cards. For cover weight
paper, a score is usually required to produce a smooth edge. |
|
|
Letter
Fold This common fold, used for mailings and brochures, is much
like a letter folded by hand for inserting in an envelope. The letter fold
produces a self-contained unit, easily handled by automated envelope
inserters. |
|
|
Z-Fold
The "Z" style offers an advantage for multi-page letters to be collated
and hand inserted for mailing. Because the pages nest together, the letter
is opened with the pages in sequence. It does tend to spring open and
should be avoided when automated envelope inserting is used. |
 |
|
Half + Letter Fold This fold is
perfect for newsletters. An 11x17 sheet folded this was has only one open
side and fits into a #10 envelope. The newsletter looks good and is easy
to handle. |
|
|
Two Parallel Fold An excellent
fold for legal size (or larger) pieces that are to be mailed. A legal
sheet (8.5x14) is folded to 3.5x8.5. A 9x16 sheet produces a 4x9, four
panel brochure. Note: A perforation added at one of the folds can create a
three panel brochure with detachable reply card. |
|
|
Accordion Fold This is the four
or five panel equivalent of the "Z" fold. It makes a nice presentation,
but may want to spring open. It can be temperamental to set up and usually
requires each panel to be about 1/32" longer than the preceding panel. It
is run tail first so that the front cover will be the widest panel. |
|
|
Half + Z Fold When used for a
newsletter, this fold has the advantage of positioning the masthead on top
of the front and the mailing panel right side up on the back. New mailing
requirements, however, would require both edges to be tabbed. |
|
|
Gate Fold The gate fold is very
attractive as the succession of message presentation is dramatic. It
requires either handwork or specialized equipment. Lining up images that
cross over the inside flaps can be very difficult. |
|
|
Barrel Fold Popular, although
sometimes tricky, the barrel fold "rolls up" a multi-panel brochure. Each
panel must be slightly longer than the preceding one. It may or may not be
a good design for a given brochure as the message tends to unroll rather
than open up to the reader. |
|
| Z FOLD with Angled
Trim An angled trim on an 8.5x11 sheet produces an
interesting presentation. Trim two of the panels at an angle and then
Z-fold. The resulting brochure or invitation unfolds like
this: |
|
| Eight Page Right
Angle Fold This is a typical fold for
booklet binding. Pages are printed four per side of the sheet, with the
correct imposition, and are folded to eight page units for collating.
Generally, these signatures will be saddle stitched to produce multi-page
booklets. |
|
| Sixteen and
Thirty-Two Page Right Angle Fold For
progressively larger books and larger press sizes, additional folding
units are added to provide more pages per
signature. |
