Guidelines for Normal
Spoilage Allowances |
| |
 |
ecause spoilage occurs in every bindery
operation, your finisher needs sufficient print overruns in order to deliver
full counts. |
The following spoilage guidelines were developed by the Graphic Finishing
Industries of Illinois to help customers plan print production needs.
Please bear in mind that these guidelines can not apply to every job, so check
with your bindery supplier to confirm their spoilage requirements.

| |
|
Inserter/Stitcher/Trimmer |
 |
(Normal job on paper stock of 45#
coated up to 100# coated)
| 1 pocket..... |
2% of the finished count, plus 500
signatures for make-ready |
| 2 pockets.... |
2 1/4% of the finished count, plus
500 signatures for make-ready |
| 3 pockets.... |
2 3/4% of the finished count, plus
500 signatures for make-ready |
| 4 pockets.... |
3% of the finished count, plus 500
signatures for make-ready |
Example: |
| |
500,000 finished books of four 8-page
signatures. Spoilage allowance 15,500 of each signature, plus 500
(four 8-page signatures; 4 pockets = 3% of 500,000 finished books or
15,000, plus 500 for make-ready = 15,500.) |
Signatures received with bent laps
could increase this spoilage guideline.
| Additional percentages: |
- 1 1/2% for one-up oblong books
- 1/2% for all two-up jobs
- 2% for 4-page signatures of 50#
book weight or lighter
- 1/2% for each 8-page signature
- 2% for jobs on uncoated stock
lighter than 45#
- 1% per vacuum-fed signature
 |
|
Flat Cutter |
 |
| 1/2% per 1,000
finished pieces |
Additional percentage: |
| |
1/4% additional
allowance for stock with remoistenable gum strip |
Example: |
| |
500,000 finished 8 1/2
x 11 flat pieces = 1/2% of 500,000 or 2,500 pieces for spoilage. |
For paper stock lighter than 45# do not use these
specifications...consult your finisher.
 |
|
| |
|
Buckle Folders |
 |
Make-ready/set-up = 1
% of stock for each folder, plus 1 % of the finished pieces.
|
|
Additional percentage: |
| |
1/2% of the folded
finished pieces for each additional folding machine section used
whether used in parallel or right angle.
|
|
Example: |
| |
100,000 17 x 22 sheets
folded to 8 1/2 x 5 1/2 (3 right angle folds) to be run on two
folders. Spoilage allowance:
1% of 100,000 or 1,000 pieces (1/2% for each of two additional
folding machine sections) plus 1% of stock for each folder set-up. |
The following items will increase basic spoilage: |
- Curly stock
- Lightweight (less than 45#
uncoated)
- Gluing or pasting
- Pin perforation
- Perforations close to the fold
- Gatefolds
|

Mechanical Binding, unlike other
binding services requires a very labor intense process. It has different
spoilage requirements than most automatic binding methods. In most
cases, the material is handled as individual units, unlike automated
processes that, after a machine is set, the theoretical “bugs” that
cause spoilage, are out of the production process. Certainly, some of
the spoilage allowances are similar. The following “additional
guidelines” also apply to Mechanical Binding. Please contact the bindery
involved, to obtain their spoilage requirements.
 |
| |
|
Additional Guidelines |
 |
| The following factors
could adversely affect these spoilage guidelines: |
| |
1. |
Condition of material as it is
packed on pallets or skids going to the finishing operation. |
| |
2. |
Stock curl. |
| |
3. |
Kind and weight of paper, depending upon application. |
| |
4. |
Numerous lots or codes. |
| |
5. |
Paper that does not lay flat due to heavy ink coverage, special
coatings, tape, spot U.V., perfs or scores. |
| |
6. |
Quality control sample pulls should be a consideration.
|
| Keep in mind the
following: |
- Additional waste occurs in
packaging.
- Allowable overrun is an
important part of the target figure; therefore, when no underrun
is allowed, an additional 10% beyond expected spoilage must be
delivered to the finisher on most jobs.
