Sign Customiser supports UV printing on neon signs, but UV print works differently from tube colours. Tube colours are still a manufacturer-defined LED palette. UV print is the printed face layer.
Update, 1 October 2026:From 1 October 2026, AI Sign Designer V2 does not add a UV print to new neon designs. Designs that already have a UV print keep it. The manual UV print options do not change. See AI neon designs now show as lit tubes.
For AI Sign Designer uploads, Sign Customiser now preserves the original artwork colours on the printed face instead of remapping them to merchant UV swatches. This keeps logos and multi-colour artwork accurate while still matching glow and tube effects to the nearest supported LED tube colour.
That means UV palette colours now have a narrower purpose: they are manual preset swatches for workflows where you intentionally want customers choosing from predefined UV print options. They are no longer the source of truth for AI artwork face colours.
What’s Changed
- Preserved AI artwork coloursAI logo uploads keep their original face colours as printed UV data instead of being snapped to a UV palette
- LED-safe glow matchingTube and halo colours still match to the nearest supported LED tube colour for accurate illuminated previews
- Hidden UV workflow supportMerchants can keep UV print available as a hidden print capability without exposing manual UV palette choices in the main neon editor
- Manual UV presets still availableUV palette entries remain useful for merchant-managed manual UV print presets and legacy face workflows
- Clearer display valuesWhen preserved artwork colours appear in admin or order data, they are labelled as
Custom UV (#HEX)so they are not confused with palette selections
