Sharpness: The antimony in the alloy ensures that the type remains sharp and clear.

Types of Type Metal

Different compositions of type metal have been used throughout history, each with its own advantages.

Foundry type: This type metal has a higher percentage of antimony, making it harder and more durable.
Monotype: Used in the Monotype machine, this alloy has a higher tin content, making it more malleable.
Linotype: The Linotype machine uses an alloy with a balanced composition of lead, tin, and antimony.
Stereotype: This type metal is used to create printing plates for high-volume printing.

The Decline of Type Metal

With the advent of modern printing technologies, the use of type metal has declined.

Phototypesetting: Introduced in the 1960s, this technology replaced type metal with photographic processes.
Digital printing: The rise of computers and digital printing in the 1980s further reduced the need for type metal.
Environmental concerns: The use of lead in type metal has raised environmental and health concerns.
Collecting: Today, type metal is often collected by enthusiasts and used in artisanal printing.
