Dot Matrix Marking

Description

What are Dot Matrix Marking Services?

A Dot Matrix is a simple grid pattern of dots used to create a number or letter as one would see on an old score board or an old computer screen. The key to legibility and definition is the density of dots. However, density can present problems in Low Stress Marking applications. The key to maintaining Low Stress while sustaining legibility is by balancing dot frequency with character size.

Advantages

Pros of Dot Matrix Marking Services

Very legible marks in clear fonts to eliminate confusion in marked text
