Security envelope dashes

 

Sprinkle them all over

 

This envelope security pattern features sprinkles all over.  Up close, they look like a mix of em and en dashes.

 

 

 

Security envelope marbled

 

Marbled

This envelope security pattern is more intricate than it looks.  The blue marbling is printed over a grey pattern.  This is done to add an extra layer of security.

 

 

 

Security envelope plaid

10 by 10 minus 1 and 10

To make this plaid pattern, start with a grid pattern rotated by 45 degrees.  Set up a 10 line by 10 line grid and on each side of that grid, remove one line.

Note that the blank areas in the pattern were caused by printer problems.

Security envelope basket woven

 

Five bars per band

 

The basket weave pattern used for this security envelope is very rustic.  The pattern does take a break at the fold line.

 

 

Security envelope polygons 2

Unlike the polygon security envelope pattern previously posted here,

 

Blue polygons

 

this polygon pattern does not seem to want to be mirrored and matched to create a bigger pattern.  Despite that hinderance, it is an interesting pattern.  

 

N.B. this pattern came from an envelope used by the same business that used the previously posted polygon pattern.

 

Addendum:  by doing a V flip and an overlay, it is possible to extend the pattern slightly in the vertical; nothing seems to inspire a further extension in the horizontal or vertical.

 

 

Just a flip and overlay

 

Maybe one of the readers can provide a way to extend this pattern?

Security envelope blue diamonds

This envelope security pattern features diamonds on blue paper.

Those are tilted squares

The registration markers can be seen in the upper corners of the wings.

Security envelope stars

It was a pleasant surprise to find this envelope security pattern of four-pointed diamond-shaped polygons.   

 

Are 4 points a star?

 

The repeating pattern itself is very small; repeated it grows massively.

 

Security envelope patterns come in different patterns that .  Usually, they are small and tightly packed, covering the whole interior of the envelope to obfuscate the contents.

It's a tee shirt!

This blue polygon pattern has been mirrored left-right and  up-down.  The tiny diamond in the center is the lower-right, lower-left, upper-right, and upper-left corner, respectively, of the pattern after the horizontal and vertical flipping and tiling.

Some sketchy V and H flips and overlays give a rough draft view of a more complete polygon security pattern.

This rough sketch demonstrates the result of enthusiastic polygon pattern and line matching.

 

adjusting lines to meet

 

It is possible to continue the process and create even denser patterns.
