    Default Learned Something New Today

    Penny O'Rorke taught me the name for the engraving patterns used on banknotes & certificates is guilloche. I've always been a fan of spirograph like patterns but didn't know it had a proper name. In her honour I issue the attached banknote...

    And a very sweet render Ross. Does this note have the potential to take-off like the bitcoin?

    Yes, I also learned "GUILLOCHE" and did some Googling on it. Thanks Penny.

    Nice banknote Ross. I'm going to have to learn a technique to do that. I've done a few fake "certificates" in the past, but they always look wrong. Do you have a technique you are willing to share?

    Egg -- Somehow I doubt the Penny Note will gain traction. If however you wish to be an early adopter I'll record you in the blockchain as the owner of 600,000,000 of the Pennies. My gift to you.

    Keith -- The guilloche approach I used was to simply superimpose two different blends of lines. I started with a wavy line (created as a sine curve), duplicated it and made a blend. I then cloned that blend but stretched and squished it so it was different than the original blend. So the guilloche effect is simply created by seeing the two sets of blend lines and their visual interaction.

    I have already designed guilloche samples for various certificates.
    Gulloche is not only a simple cross-blend but also requires creativity. For Adobe Illustrator there are a few plugins that can generate patterns. In Xara I do everything by hand.
    Here's a little example:

    Thanks for the compliments.
    But in Xara it is easy to achieve good results.
    Using the rosette as an example, I only used smart shapes.
    In the variations you can generate many different patterns and forms from a single blend.
    Everything is quick and easy.
