Guilloché Patterns

Published on 10 October 2008

If you wanted to design your own bank notes or passport you might consider using a Guilloché pattern as one of your anti-counterfeiting measures.

I first heard about Guilloché patterns in a recent post over at the Ministry of Type blog run by Aegir Hallmundur. Guilloché machines (also known as geometric lathes) have been used since the 17th century by watchmakers and goldsmiths, such as Fabergè, for for ornamentation.

Using the set of Hypotrochoid equations Aegir describes I've built a little Flash app to experiment with the various parameters. Click the picture below to play.

Download the AS3 source code and play with the Guilloché explorer.

  Daniel - if you press 's' you can save the image out as a JPEG.

  Remarkable control board!
  Very stylish, but on this MacBook, dark grey on darkish grey is close to unreadable.

  Which control is which?

• Tom commented at 2 January 2009 at 07:35

  Thanks Tim. If you select white from the bottom colour picker then the text/background colour combination will reverse to make it more readable.

  Is there (or will there be) an animatable version for After Effects?

• Tom commented at 6 January 2009 at 07:12

  John, at the moment there isn't a version for After Effects I'm afraid.

  "..your own bank notes or passport.." Yeah, or a "big check", or a post card as well..

  That's really cool - a "save to svg" option would be awesome though.

  Reminds me of the old Hasbro Spirograph I used to play with as a youngster.

  Wow, this is fatastic and got my creativity going immediately. There are so many combinations to try!
  Are we allowed to use the generated pattern in pictures and such?

• Tom commented at 1 April 2009 at 07:27

  Thanks Nini. Feel free to use the patterns however you like.

  is there any possibilities to export it to vector format?
  i'm building my own country from scratch now, need to make currency first, would be great if can make that with this pattern :D
  can someone please tell me how to export it to vector pretty pleasee :D

• Warren commented at 24 June 2009 at 05:30

  All your apps are awesome. I was searching for some vector patterns for a background on a voucher I'm creating and found this.

  BTW, choose the print function, print as PDF, open in Illustrator and you got vector.

  Hi,
  Try to use Cerberus - professional guilloche editor - with all build-in filters (www.guard-soft.com). All results in .ai format - make and print! :)
  Best regards,
  Serge

  I have been looking for something like this for a long time! I love it. This app is extremely cool.

  Great programmer!

  Please add an option to save it to vector!
