Approved variations of the logo include the blue-and-grey and the white version. These may be used on white, coloured, or transparent backgrounds, provided that readability and visual integrity are maintained.

Improper Use of the IRIS Certification® Logo
The logo must not be altered in any way. This includes changing the font, removing the copyright symbol, tilting the logo, removing the baseline, changing the aspect ratio, modifying elements or colours, adding borders or shadows, or using outdated versions of the logo.

Use of the IRIS Certification® Logo at Events
IRIS certified companies often display the IRIS Certification® logo at events, including on exhibition panels, certificates, promotional posters, product displays, partner boards, and digital screens.
