Type 1 – Stain Mark


Also sometimes referred to as Dark Mark, Laser Mark, Dark Laser Mark, Out Of Focus Stain Mark

This dark annealed marking is often used on medical devices and components that benefit from a non-disrupted surface, or in cases where a customer wants the look and smooth “feel” of the marking. There are occasions where customers will have laser etch, or even laser engrave on their prints while really wanting a stain mark. This marking is generally performed per our NL-DM-01 internal specification.
