Banknote patterns fascinate me. 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. Central to banknote designs are Guilloche patterns, which can be created mechanically with a geometric lathe, or more likely these days, mathematically. The mathematical process attracted me immediately as I don’t have a geometric lathe and nor do I have anywhere to put one. 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. 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. The process took ages and served just to prove to me that I could do it, but the results were too poor to go much further.
Excentro is a simple tool that allows computer artist create Guilloche designs in comfortable environment of Macintosh computer. 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.

Then, a couple of years later I discovered Grapher on the Mac. Aha! Now here was a program that could create the patterns I was after and export to EPS. Well, kind of. It could create the patterns, most of the time, and export to EPS, though not always. I got a couple of patterns out of it and had a look round for other options. Again, not much - not much that I could afford, that is.
Then we get to now. I give Grapher another go, and at last, I can create and export patterns:
There are still some extremely frustrating limitations though. First of these is the resolution of drawing the graph. I’m sure for most graphs the default resolution is fine, but when creating these patterns you need tiny increments. Tiny tiny ones. If the line is going from one side of the graph to the other and back again a thousand times in a couple of radians, you don’t want the graph program to start dropping line segments, or corners, or anything really. Grapher does allow you to increase the resolution, but it’s not sticky - change anything in the equation and it pops right back to the default. Every. Single. Time. The same thing seems to happen with the line thickness too - I wanted all the designs to be at 0.1, but it kept changing it back to 1.0. Frustrating! There are a couple of other UI things I’d change, like having an option to keep axes at 1:1 ratio to each other, even when you resize the window.
Another, deeply irritating frustration with the whole process is to do with Illustrator. Try and open an exported EPS in it, and you get “An unknown error occurred”. Photoshop can accept the EPSs as placed objects, and InkScape can (eventually) open them, so Grapher seems to be outputting valid EPS files. I suspect that the number of lines in the graph is causing the premier vector editing app in the industry to fall over. Oh dear.
Still, after all this, I can still get the patterns made, and get them into an image editing program, which is quite something. Now I just need to find the magic numbers to create just the right patterns I want.
Note: 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. 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.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 UI is a little palette-heavy (it can feel a bit crowded) but is perfectly usable and extraordinarily powerful.Today we will talk about the technique of creating guilloche pattern vectors using the Envelope Distort, Blend Tool and Pattern Brush. Guilloche pattern vectors are commonly used to protect the securities and banknotes from counterfeiting. Usually, to generate a guilloche pattern vector, designers use special expensive software. You might not have known that Adobe Illustrator helps to create guilloche pattern vectors, using only native features. Let’s see how it’s done!

Final Image: Guilloche Pattern Vector
Step 1
To begin this guilloche pattern vector tutorial, open Adobe Illustrator and create a new document (Cmd / Ctrl + N). Your artboard can be any size. The guilloche pattern vector we’ll create will work equally well in the RGB and in the CMYK color modes.
Step 2
Take the Pen Tool (P) and draw a wavy line with no fill like shown in the picture below. You do not need to repeat the exact shape of the curve – just place the handles of the start point and end point of the path horizontally. To do this, hold down the Shift key while manipulating it.
Create another curve below the first one. The start and end point of the curve also has handles placed horizontally.
Step 3
Select the start points of the two paths using the Direct Selection Tool (A), then align them horizontally by clicking on the Horizontal Align Left in the Align panel.
The same way align end points of paths. Microsoft office 2019 for mac 16 33 download free.
Step 4
Connect the start points of the paths using the Pen Tool (P).
Select the achieved path, take the Reflect Tool (O) and click at the point A, holding Option / Alt. In the dialog box, choose Vertical axis and hit Copy button.
Step 5
For the next step of this guilloche pattern vector tutorial, select the upper points at which both paths intersect using the Direct Selection Tool (A), then go to Object > Path > Join (Cmd / Ctrl + J).
In the same way we’ll connect the lower points of the path.
Step 6
Create a horizontal path with no fill using the Pen Tool (P) or the Line Tool ().
The path length is not significant. Move the path at some distance down, holding Shift and Option / Alt, which should result in its duplication.
Step 7
Select both straight-line segments, then use Cmd / Ctrl + Option / Alt + B shortcut to create a blend of the object. Now double click on the Blend Tool (W) icon in the Tools panel. In the opened dialog box, choose the Specified Distance and set 4px in a numeric field.
If you want to create a colored guilloche pattern, you can recolor strokes of the paths in different colors, such as red and green.
Step 8
Place blends object below the object of wavy paths, to do this move it down in the Layers panel.
Select all the created objects, then go to Object > Envelope Distort > Make with Top Object.
As you can see, we got a few defects in the beginning of this guilloche pattern vector, which are indicated by arrows in the picture above. To correct them go to Object > Envelope Distort > Envelope Options … and increase the Fidelity up to the value of 90-100.

Now all the defects are eliminated.
Step 9
Drag the resulting object in the Brushes panel, and in the dialog box, choose the Pattern Brush option.
Without changing the settings in the next dialog box, click on OK. If you are using Adobe Illustrator CC-CC2014, then you have the ability to automatically generate a corner tile. To do this, you have four options to choose from. This will give us an opportunity to apply the brush to the shapes that have angles.
Step 10
Create a circle with stroke and no fill using the Ellipse Tool (L), then apply the created brush to it.
As you can see, we got a fairly complex shape, which is our new guilloche pattern vector! This object is dynamic. Double click on a thumbnail of the brush in the Brushes panel to open the dialog box. Now let’s play with the parameters observing the occurring changes.
Now let’s see how our guilloche pattern vector will look like, if you apply the brush to a rectangular shape.
Conclusion: Your Own Guilloche Pattern Vector!
We have reviewed the basic technique of creating our guilloche pattern vector in Adobe Illustrator. Now I would like to point you the direction for your own experiments.
a. As you know, the object created in steps 2-5, can be of a completely random shape. The more objects you create, the more kinds of the guilloche pattern vector you’ll get.
b. You can change the color of the blend object and the value of its step.
c. Blend object may consist of paths of different shapes (not only of straight line segments). For example, we can use the path in the shape of a zigzag. The pictures below show the intermediate steps and the final result of the created guilloche pattern.

d. Instead of a blend object, you can use the path to which the pattern brush is applied. I created a brush element of several squares (angles of the lower square and upper one are rounded).
Let’s keep this place as a pattern brush in the Brushes panel, then apply the brush to the straight-line segment.
Now, following the instructions that you are familiar with, you can make a new guilloche pattern vector!
