Universities and training centers use Securidesign to generate unique, color-shifting backgrounds. Each diploma can have a different serial number and a custom guilloche pattern corresponding to the year of issue.
| Error Message | Likely Cause | Solution |
|---------------|--------------|----------|
| “Macro not found” | Incorrect GMS folder location | Move the .gms file to the correct %appdata% path. |
| “Out of memory” | Too many nodes in the pattern | Reduce guilloche density or split the design across multiple pages. |

Guilloche is an intricate, repetitive pattern of intertwining lines, often seen on banknotes and stock certificates. Securidesign allows you to: Securidesign For Corel Draw X7 25
Standard CorelDRAW allows text on a curve, but not at the extreme small sizes required for security (often 4pt or less). Securidesign optimizes the rendering engine to prevent the text from breaking apart. You can type a string like "AUTHENTIC DOCUMENT" and repeat it thousands of times around a circle, automatically adjusting spacing.
While newer versions of CorelDRAW exist, version X7 remains a staple in many design firms due to its stability and toolset. SecuriDesign extends the lifecycle of X7 by enabling it to compete with high-end, specialized security software that costs thousands of dollars more. Security design relies on repeating geometric chaos
The benefits include:
Draw a small circle, select it, and click the “Guilloche” button. If a complex pattern appears inside the circle, the installation was successful. Guilloche is an intricate
Security design relies on repeating geometric chaos. This tool generates overlapping diamonds and wavy lines that create an optical illusion of depth. These patterns can be set to "void" (white lines on color) or "solid" (color lines on white).
As of 2025, the developer of Securidesign has not released an official patch for CorelDRAW 2025. The "X7 25" version has been reverse-engineered by some users to work on X8 (2016) and 2018, but not reliably on 2021+ due to deprecated VBA7 calls.
Your best bet for long-term stability is to preserve a virtual machine running Windows 10 LTSC and CorelDRAW X7 specifically for running your Securidesign For Corel Draw X7 25 environment. Do not upgrade your OS or Corel version if this tool is mission-critical.
