Vertical writing for Chinese-Japanese-Korean signs
Sign Customiser now supports proper top-down vertical writing for multilingual signs. Merchants can configure whether vertical columns read right to left or left to right, so customers can type natural multi-line text while the preview and manufacturing output keep the intended layout.

What’s Changed
- Multi-column vertical text - Each typed line becomes its own top-down column, making vertical Japanese, Traditional Chinese, Korean, and traditional Mongolian layouts practical for customer-facing customisers
- Merchant-controlled column direction - Choose right-to-left columns for Japanese, Traditional Chinese, and Korean signs, or left-to-right columns for traditional Mongolian signs
- Natural order details - Cart details, order data, and exports keep the customer’s original typed text instead of replacing it with a generated column representation
- Pricing stays logical - Base line pricing follows the typed input lines while letter charges still apply to each visible character
- Font guidance in settings - The admin settings now remind merchants to upload fonts with the glyph coverage needed for their target language

Address sign numbers with vertical stacked text
Sign Customiser now supports vertical stacked text and ships with a ready-made Address Sign Numbers customiser that uses it by default. Customers can stack each digit or letter on its own line for door numbers, house plaques, and any signage where characters need to read top to bottom rather than left to right.

What’s Changed
- New Address Sign Numbers product type - Pick “Address Sign Numbers” in the customiser create flow to spin up a new acrylic-backed customiser tuned for door and house numbers, with the orientation toggle already enabled
- Vertical stacked text orientation - A new orientation control lets each character drop onto its own line, with positions, sizing, and pricing all calculated from the stacked layout rather than a horizontal row
- Three orientation modes per customiser - Lock the customiser to horizontal only, lock it to vertical stacked only, or let customers switch between the two from a Horizontal / Vertical toggle next to the text input
- Configurable default orientation - Choose whether the customiser opens with horizontal or vertical selected when both options are available, so the most common choice is just one click
- Customisable orientation labels - Override the “Horizontal” and “Vertical” labels from the Labels page to match your store’s voice or translate them into another language

RGB Colour Options for Channel Letter Signs
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 letters - Customers 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 transitions - The 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 types - The rainbow gradient colour swatch that previews multi-colour options is now available across all product types, not just neon signs
- Built-in demo data - New 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

AI Sign Designer enhanced logo and image editing capabilities
Sign Customiser’s AI Sign Designer now features powerful image editing capabilities with significant performance improvements and enhanced functionality.
Key Enhancements
Transparency Support Fixed
Critical issues with generating images containing transparency have been resolved. Logos with transparent backgrounds are now handled correctly, maintaining their intended visual appearance across all sign materials including neon and acrylic.
Improved Shape Interpretation for Complex Images
Enhanced shape detection algorithms now provide superior interpretation of busy and complex images. The AI Sign Designer can better distinguish between overlapping elements, handle intricate patterns, and accurately identify shapes in visually dense designs. This improvement ensures that even the most detailed logos and graphics are converted with precision, maintaining the integrity of complex brand elements.
