ABSTRACT:
A portion or component of a metal container is provided with markings or indicia using laser light. High-speed laser steering is used to position laser light or laser light pulses across a lateral and longitudinal extent in a relatively short time period such as a time period selected so as to avoid slowing, stopping or otherwise interfering with other container or container component production processes. Preferably, tab stock for container-opening tabs can be provided with 6 to 9 or more visible characters within a time window of 50 to 100 milliseconds or less. Preferably, the size and resolution provided by the pulses are sufficient to permit legible, and preferably attractive, formation of any standard typewriter characters. In one embodiment, other logos, designs, textures, backgrounds and similar features can be provided.
