Developer's Description By Excourse Excentro is a simple tool that allows computer artist create Guilloche designs in comfortable environment of Macintosh computer. Note 2 (27th August 2010): I have since bought Excentro and have used it on several projects, including this one for Wired, and I can confirm it is an excellent tool. The guilloches are vintage design elements that were frequently used. I played a bit with Excentro and it certainly makes some things a hell of a lot easier - but I’ll hold off buying it for now until I’ve got an actual project I can use it for. By Excourse Excentro is a simple but advanced tool that can create guilloche designs like backgrounds, borders or rosettes. Note: Excentro 1 9 12 – Create Guilloche Illustration Designs For Beginners I know there are programs devoted to creating these patterns - Excentro being apparently one of the most popular, but I’d rather use the software tools I already own first. Now I just need to find the magic numbers to create just the right patterns I want. Still, after all this, I can still get the patterns made, and get them into an image editing program, which is quite something. Excentro, a software made for the creation of guilloche patterns. Guilloches (bands of thin intertwining lines like ones you can see on banknotes) were traditionally used for security printing as a protection against counterfeit and forgery.

So off I went, using the hypotrochoid equations on Mathworld to create rather rough and ready patterns - scripting at this point didn’t have a very usable set of functions for creating beziers, so I had to use crummy line segments. I do, however, have a computer, and at the point I first started playing with the designs (mid-2004) Illustrator and Photoshop had gained the ability to be scripted. The mathematical process attracted me immediately as I don’t have a geometric lathe and nor do I have anywhere to put one. Central to banknote designs are Guilloche patterns, which can be created mechanically with a geometric lathe, or more likely these days, mathematically. I can get lost for hours in all the details, seeing how the patterns fit together, how the lettering works, the tiny security ‘flaws’ - they’re amazing.
