Check out this incredible video by Tension Corporation. Over the years I have seen many envelope making videos, but this has to be the clearest and most descriptive video of the whole process, and it specifically mentions how security envelopes are made!
“With the expertise and equipment at Tension, it only takes about 20 seconds for an envelope to travel from the beginning to the end of the process.”
I first learned about Tension through Maynard Benjamin’s “The History of Envelopes 1840-1900.” I’ve looked into many of the companies mentioned in this book. Some of the companies are still in business an doing some incredible things.
The excess panel chips, the sections that are cutout for the window pane, could make for good artwork material. What do you think?
Here are different parts of the printing process mentioned.
- Web converter
- Web tower
- Cross Cutter
- Scoring
- Gumming
- Side-seam Folding
- Creasing
- Delivery spirals
Above all, the testing and verification of settings and performance through this printing process is remarkable.
