L-shaped perforation

[Creative-1]

I have the need to do an L-shaped perf at the top corner of a sheet of 14 pt stock. The purpose would be so that a card could be removed from the sheet. My problem is that we perforate on our folder and don't have a way to stop the perf from running the length of the sheet. We do have a small AB Dick duplicator, but have never perfed on it. Any ideas on how this might be accomplished?

Sounds like either litho perf on the press or a letterpress die.

We use Litho Perf and Litho Score from H.S. Boyd, it does the job just fine for us on presses.

Someone told me that litho perf couldn't go through a 14pt sheet.

I would try it and see how it looks. the letter press option is going to be more expensive

Thanks everyone. I am going to order the Litho Perfs and give them a try.

Perfect Perf from Thompson Manufacturing does the exact same thing, mounts to the press in the exact same way and costs a lot less. Yes it,s just as good of quality. They manufacture the stuff in Tulsa and can be reached at (918)-585-1991. Just use that and keep the rest of your money in YOUR pocket!

If this is something you are doing all the time you might look at purchasing a perforator that does a "strike stop" perforation. I know Graphics Whizard has one that you can program and of course Rollem has something as well.

Downside to this is that you have to run the item through the perforator twice, once for each perf direction.

I would try turning up your cylinder pressure via the dial behind the hand wheel. You can also try putting a bit of packing under the blanket to build it up and creat more pressure for the perf. Don't forget litho perf will wreck your blanket so use an older one.

The quality of Boyd's products and Thompson's products are not the same !!! Please compare the two products and see for yourself.

Boyd has a new product line called Precision Perf that is .035" tall that will indeed work on the 14pt. stock you mention.

We now have a machine capable to T and L perf in one pass. We have adapted our Creasing machine with an impact perf that works across the sheet and the strike perf that works along the length.

If you have any questions please call me anytime and I will get you information
