How to Use SecuriDesign for CorelDRAW X7 to Create Stunning Security Designs

SecuriDesign is a set of macros for CorelDRAW X7 that allows you to create various designs used frequently in security printing, such as certificates, bank notes, documents, and so on. With SecuriDesign, you can easily create guilloche patterns, rosettes, contours, and fills right in your CorelDRAW document. In this article, we will show you how to use SecuriDesign for CorelDRAW X7 to create stunning security designs.

SecuriDesign consists of three basic modules: Contour Generator, Pattern Generator, and Function Editor. You can access them from the SecuriDesign toolbar that was created when you installed SecuriDesign on your system:

Alternatively, you can launch them by going to Tools>Visual Basic>Play… dialog and choosing “SecuriDesign (SecuriDesign.gms)” from “Macros in:” list. You will see the three macros in the “Macro Name:” list:

Select the macro you need and click “Run” button. The macro will be launched.

Contour Generator

Contour Generator is similar to the Contour effect in CorelDRAW with the exception of CorelDRAW’s effect creating contour lines with constant offset from a control object. SecuriDesign uses harmonic functions to modulate the offset and thus easily generates base curves for various design elements such as rosettes. To use Contour Generator, follow these steps:

1. Select a curve object in your document that you want to use as a control object.
2. Click on the Contour Generator button on the SecuriDesign toolbar or run the macro from the dialog.
3. The Contour Generator dialog will appear. Here you can adjust various parameters of the contour, such as number of steps, offset range, function type, frequency, phase, amplitude, etc. You can also use the Function Editor to create your own custom function for the contour.
4. Click on the Preview button to see how the contour will look like. You can also click on the Apply button to create the contour in your document.

Here is an example of a rosette created with Contour Generator:

Pattern Generator

Pattern Generator is used to produce guilloche “fills” between two selected curves in your document. You need to have two curve shapes which are used as envelopes for the pattern. The resulting fill follows the path of both envelopes. You can use either the contour curves created by the Contour Generator or you can draw any curves using CorelDRAW’s drawing tools. Pattern Generator allows you to generate complex designs in one step. To use Pattern Generator, follow these steps:

1. Select two curve objects in your document that you want to use as envelopes for the pattern.
2. Click on the Pattern Generator button on the SecuriDesign toolbar or run the macro from the dialog.
3. The Pattern Generator dialog will appear. Here you can adjust various parameters of the pattern, such as number of lines, line width, line color, line style, function type, frequency, phase, amplitude, etc. You can also use the Function Editor to create your own custom function for the pattern.
4. Click on the Preview button to see how the pattern will look like. You can also click on the Apply button to create the pattern in your document.

Here is an example of a guilloche fill created with Pattern Generator:

Function Editor

Function Editor is used to create mathematical functions used by both Contour and Pattern Generator when creating contours and patterns. You specify a function description as a set of Fourier coefficients or you can draw a function in your document and have the Function Editor to “digitize” the function and produce the coefficients
