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.
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 colours - AI logo uploads keep their original face colours as printed UV data instead of being snapped to a UV palette
- LED-safe glow matching - Tube and halo colours still match to the nearest supported LED tube colour for accurate illuminated previews
- Hidden UV workflow support - Merchants 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 available - UV palette entries remain useful for merchant-managed manual UV print presets and legacy face workflows
- Clearer display values - When preserved artwork colours appear in admin or order data, they are labelled as
Custom UV (#HEX)so they are not confused with palette selections
