Sign Customiser now brings the popular RGB colour effect to channel letter signs. Your customers can select RGB as a face or halo colour option and see a smooth, animated colour transition directly in the live preview — helping them visualise exactly how their sign will look with colour-changing LEDs before they buy.

What’s Changed

• RGB colour option for channel lettersCustomers can now choose an RGB multi-colour option for both the face and halo colours on channel letter signs, complete with an animated preview that cycles through the full colour palette
• Animated colour transitionsThe live sign preview smoothly blends between colours in real time, giving customers a realistic sense of how RGB LED lighting will look on their finished sign
• Colour preview swatches for all product typesThe rainbow gradient colour swatch that previews multi-colour options is now available across all product types, not just neon signs
• Built-in demo dataNew channel letter customisers come pre-loaded with an RGB option on both face and halo colour palettes, priced at a 10% uplift by default so you can start selling immediately

Sign Customiser now lets merchants control whether optional letter parts — like face colours or lighting effects — are pre-selected or left blank when a customer first opens the customiser. This gives you more flexibility over the initial sign preview and can simplify the buying experience for products where certain parts are truly add-ons.

What’s Changed

• New “Default to none” settingWhen editing an optional colour selection in the admin, a new checkbox lets you choose whether the part starts unselected when the customiser loads
• Cleaner starting experienceCustomers see a simpler sign preview by default and can add optional parts as they explore, rather than needing to remove pre-selected options
• Backwards compatibleExisting optional parts continue to behave exactly as before, pre-selecting the first available colour

You can now add a Letter Rail backboard to any channel sign customiser. Letter rail backboards display individual letters mounted on a sleek rail, offering a modern and versatile look without needing to set up a separate sign type.

What’s Changed

• New Letter Rail backboard optionLetter Rail is now available as a backboard support type alongside Board, Raceway, Stand and Cut to Shape, configurable from the backboard editor on any channel sign customiser
• Configurable bar height and gapControl the rail thickness and the spacing between the rail and the letters from the backboard padding settings
• Automatic style inheritanceLetter rail backboards can inherit the same face colour and glow effects from the letters, ensuring a cohesive look without any extra configuration

Sign Customiser’s font engine has been completely upgraded to support a much wider range of international fonts and scripts. Customers designing signs in Arabic, Hebrew, Chinese, Japanese, Korean, and other non-Latin languages will now see accurate letter rendering, correct text shaping, and reliable measurements — opening up your customiser to a truly global audience.

What’s Changed

• Thousands more compatible fontsThe customiser now works with a significantly broader range of modern font formats, unlocking thousands of additional fonts from Google Fonts and custom uploads
• Right-to-left language supportArabic, Hebrew, and other RTL scripts now render correctly with proper letter joining, ligatures, and contextual shaping
• Accurate international measurementsSign dimensions and pricing are now calculated accurately for complex scripts where characters change shape based on their position in a word
• Better multi-language signsMixing fonts from different languages on the same sign now produces more consistent sizing and spacing
• Improved font cachingFonts load faster on return visits with more reliable caching, even when customers navigate away and come back to the customiser

Sign Customiser now automatically captures Google Ads click IDs (gclid, gbraid, and wbraid) from your customers’ sessions, giving you full visibility into which ad campaigns are driving sign orders and quote requests.

What’s Changed

• Click IDs included in form submissionsQuote requests and custom design submissions now pass ad tracking data through to your order emails and webhooks
• Ad tracking in order emailsMerchant notification emails now display Google Ads click IDs when available, making it easy to match orders to campaigns

• Cross-iframe supportClick IDs are correctly passed through to the customiser even when embedded via iframe on Shopify, WooCommerce, or hosted pages

Sign Customiser now gives merchants the ability to disable the size limit popup that appears when customers exceed maximum sign dimensions. This new setting provides greater control over the customer experience, allowing merchants who prefer a less restrictive design flow to remove the interruption while still enforcing size limits in the background.

What’s Changed

• New admin settingA “Disable size limit popup” checkbox has been added to the customiser settings panel, giving merchants a simple toggle to control popup visibility
• Smoother design experienceWhen enabled, customers can continue designing without being interrupted by the “Size is over the limit. Contact us for a quote” modal
• Backward compatibleThe setting defaults to off, so all existing customisers continue to behave exactly as before

Sign Customiser’s Flow RGB effect now produces a beautiful, realistic neon glow that flows across your entire sign. Each word is lit with a smooth colour gradient that shifts naturally based on its position, creating the appearance of real RGB LED tubing cycling through colours in sequence.

What’s Changed

• Multi-layer neon glowFour glow layers create a rich, realistic neon tube appearance with soft light falloff that closely mimics real RGB LED signage
• Spatial gradient animationColours flow smoothly across words based on their position on the canvas, so multi-word signs display a natural colour wave rather than each word changing independently
• Optimised for all devicesFrame throttling and reduced glow layers ensure smooth performance on mobile devices and Safari, without sacrificing visual quality
• White face with coloured glowThe text itself remains crisp white while the surrounding glow cycles through your chosen RGB colours, just like real neon tubing

No action is needed on your end — this effect applies automatically to any customiser that already uses the Flow RGB colour effect.
