In the advertising output field, "Composite Board" (合成板) typically refers to a display board made from Foam Core Board with a printed graphic mounted or directly printed onto it.

Below is a simplified process for the design and production of advertising foam core boards (mounted or direct-printed):

Simplified Design and Production Process for Foam Core Boards

1. Design & File Prep:
   • Design: Create the graphic and text content based on the advertising purpose (e.g., human-sized standee, exhibition backdrop), confirming the overall dimensions and visual effects.
   • File Finalization: Set the graphic file to CMYK color mode, ensure sufficient resolution (typically ), and include a bleed area outside the trim line. If a special shape is needed, a die-cut line must be drawn.
2. Select Production Method:
   • Traditional Mounting: Large format printing  Cold lamination (applying a protective film)  Mounting onto the foam core board.
   • UV Direct Printing (Preferred): The graphic is printed directly onto the surface of the foam core board (high efficiency, less prone to bubbling).
3. Print & Mount:
   • Perform large format printing or  direct printing.
   • If using the mounting method, the graphic must be smoothly adhered to the cut foam core board, ensuring no air bubbles are trapped.
4. Finishing & Cutting:
   • Use a cutting machine or plotter to precisely trim the board to the final size or shape according to the die-cut line.
5. QC & Delivery:
   • Inspect the print quality, mounting flatness, and cutting accuracy before packaging and delivering the product to the client or installation site.

Key Takeaway: The dimensions and die-cut lines of the design file must precisely match the final intended use of the product.
