Help and technical notes
Here you will find notes on system requirements, download security, export formats, QR code tests and contact options.
Download security
Public downloads are only shown when release data, platform details and SHA-256 checksums are fully entered.
Export and readability
SVG is usually the best choice for print layouts. PNG or WEBP are suitable for websites, Office documents and quick sharing.
QR code tests
Before printing or display, QR codes should be tested with multiple devices, in real size and from a typical distance.
Contact
Contact and operator details are available in the legal notice. The privacy policy separately explains which data is processed when visiting the website.
Check target URLs
Before publishing, verify that links are reachable, use HTTPS and will remain available under the same address for the intended lifetime.
Report issues
For reproducible problems, include the operating system, Codemark version, export format, sample content and a short description of the steps.
