If you are producing a saddle-stitched or perfect bound book with tear-out pages, it requires a perf be placed close to the spine. Typically the perf is about ¼” away from the spine. The figure at the upper right illustrates an imposition for a 16-page signature and then the final signature with a perforation placed closed to the spine on each of the pages. The folding sequence:
- In the main parallel section, fold in half plus perf the head with conventional perf to release air
- In the eight page right angle section—fold in half again and use the CP Applicator to apply 1 score and 2 perfs for the tear out pages. Here we are perforating through 4 sheets as they pass through the slitter shafts of the 8-page section. (photo at right)
- In the 16-page right angle section—do the final fold on the spine
Because the perfs are so close to the spine, you’ll need to score between the perfs to ensure accurate folding. There are exceptions to this rule depending on paper, grain direction, perf teeth/inch, etc. In most cases you will probably need a score. With the CP Applicator you always have the score available and if it’s not needed, you can remove it and run two perfs.
This same concept can also be applied to 4, 8, 12 page signatures, and more.
When you fold card stock, you always need to apply a crease to allow it to fold properly. If the card stock also has perforated tear-off panels, you again have the problem of applying two perforations and one crease in close proximity. The CP Applicator lets you do that easily. Position the perfs as needed in relation to the crease.
Also with card stock you’ll often need to eliminate fiber cracking. With the CP Applicator you get the same creasing capability as you have with the Tri-Creaser®.
Without the CP Applicator, the jobs described above have to be run through the folding machine twice—once for the perforations and once for the score. Another alternative is to perf on press and then score and fold on the folder. Not only do both scenarios multiply the cost and time required to do the job, they add another layer of needless complication.
It is for instance, more difficult to feed and run a pre-perfed sheet through a folder. The sheet isn’t flat and perforations often stick together in the feeding section, causing numerous doubles. In addition, the time spent on press for perforating (for which you probably don’t charge) is time that could be spent producing a profitable job. You lose money on two counts.
When you run signatures with the CP Applicator you go right from the press to the folder. In the case of card stocks, you go right from the guillotine to the folder. Your savings add up:+ Flat sheets = faster production on the folder
+ Flat sheets = better register on the folder
+ One folder operation = more profit on the press instead of non-chargeable perforating time
+ One folder operation = more profit on the folder instead of a non-chargeable second pass
+ One folder operation = time normally spent on second pass can now run another profitable job
+ If you currently outsource this type of work, you can eliminate that time and expense by keeping it all in-house
As you can see, when you do the job correctly by reducing unprofitable second operations, you instantly increase profits. It’s not uncommon for users of the CP Applicator to pay for their tool in the first few jobs, or even the first job itself.
- Signatures as described above
- Tickets, vouchers, or other folded card stock with the perforation close to the fold or score
- Order forms with a perforation close to the fold
- Regular creasing jobs. The CP Applicator does double-duty as a creasing tool. Run it by itself or run it as an additional creasing tool along with your other Tri-Creasers or other Technifold tools.
- Regular perforating jobs. It also doubles as a regular perforating tool. Run it alone or in conjunction with other Technifold tools.
The diagrams below illustrate the five combinations of perf and crease you can run using your CP Applicator.
- Perfs can be spaced as close as 5mm (1/4”) apart from each other and as far away as 50mm (approximately 2 inches)
- When running two perfs with the score, you can position the perforations as close as ¼” from the score on either side, up to 1” from the score on either side
- 3 female channels are included, each with a different width.
- 3 different profiles of creasing rib included. Choose the rib + female channel combination perfectly suited for the paper you’re running.
- 2 nylon perforating sleeves included. Each has a different diameter which helps to compensate for changes in paper caliper.
- 3 perforating blades include—1 ea. 17, 25, and 52 teeth/inch. Other optional blades also available.
- Maximum caliper you can perforate—approximately 16-18 pt combined thickness. In other words you can do up to 4 sheets of .004-.0045” in one pass.
