White Dot is a printing term for a base layer of white ink placed underneath artwork when printing on clear, colored, or metallic materials. This white underprint creates an opaque foundation so the printed colors appear brighter, more accurate, and easier to read instead of looking muted or transparent.
White dot is commonly used for clear labels, metallic films, windowed packaging, and specialty substrates where you want the design to pop. It is typically set up as a separate spot color layer in the print file, and it can be applied behind the entire design or only behind specific elements like logos and text.
