How to measure a window on an envelope correctly.
Always place the envelope in front of you with the flap at the top. Measure the height of the window first then the width. The first measurement is always considered the height and the second measurement the width. This indicates whether the window is vertical or horizontal to the flap. The position of the window should be measured from the left of the envelope to the left of the window and then from the bottom of the envelope to the bottom of the window.

What is Flexographic ("Flexo") printing?
A printing method using water based, fast drying inks and photopolymer plastic plates. The plastic plate carries the ink and transfers it directly to the paper. Flexo printing is often done as an "in-line" process on an envelope converting machine.
What is Lithographic ("Litho") printing?
A printing method sometimes called offset printing. Litho uses oil based inks and metal plates. In Litho printing the metal plate transfers the ink to a rubber blanketed cylinder that in turn transfers the ink to the paper. Litho printing is a higher quality process that can be performed on flat sheets prior to converting or on folded envelopes. The complexity of the image to be printed will determine the more suitable method. It is strictly an "off-line" process.
What is the difference between diagonal seam vs. side seam?
Diagonal seams are configured with pointed or triangular flaps to create diagonal seams across the back of the envelope. Side seams are located at the side of the envelope and run nearly parallel to the side folds.
