What exactly is foil printing and how does it differ from metallic ink?

Foil printing bonds a thin metallic film onto paper using heat and pressure, giving a true reflective, mirror-like shine. Metallic ink only approximates that look with shimmer particles suspended in the ink, so the difference is easy to see side by side.

Foil comes in shades like gold, silver, and copper, and it stands out most when it catches the light. Choose foil when you want a genuine metallic pop rather than a hint of sheen.
