CMYK Artwork
HP Metallic Ink
Substrate (Paper)

Print Result

Metallic prints first, CMYK on top. Creates a muted shimmer effect that shows through transparent areas of your CMYK artwork.

Why This Works

Because the metallic ink is set to overprint, there's no knockout hole in the CMYK layer. This means the press operator can choose to print the metallic above or below CMYK without rebuilding your file. Without overprint, the layer order would be fixed by the knockout dependencies.
