Hot metal typesetting¶
In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing.
Core Idea¶
Hot metal typesetting is treated here as the recurring social sciences, humanities, and arts identity summarized by this source-grounded definition: In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing. In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing. This method injects molten type metal into a mold that has the shape of one or more glyphs.
Scope of Application¶
-
Linotype. Various methods were used to power the Linotype / Intertype machines, the most common being a fractional horsepower motor, one wired for single-phase 60 Hz alternating current eventually becoming the default offering.
-
Types of typesetting. The Super-caster, another machine produced by Monotype, was similar in function to the Thompson, Barth, pivotal and other casters but designed to produce single type (including even larger sizes) for hand.
-
The Monoline, a very basic machine. Another essential difference between Monotype and the "slug"-producing machines is that a Monotype machine functions with a minimal set of matrices.
-
The Monoline, a very basic machine. Linecasters cannot function this way, and these systems need quite large magazines of matrices to be able to set a complete line of text with the usual character repetitions.
-
Linotype. Since the type used was proportional and not fixed in width, solving this justification problem mechanically was very important.
Clarity¶
A clear use of Hot metal typesetting names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing.
Manages Complexity¶
Hot metal typesetting compresses multiple social sciences, humanities, and arts details into a stable diagnostic relation. The source shows both the central mechanism—the mold disk then turns to present the line at the ejecting position, in the process passing by a knife that trims the base of the slug to type height (0.918″ on US machines).—and the practical consequence—as part of this process, ‘plus metal’ is.
Abstract Reasoning¶
- Type the carrier. Identify the social sciences, humanities, and arts entities to which the claim applies.
- State the relation. Use the source-grounded identity: In printing and typography, hot metal typesetting (also called mechanical typesetting, hot lead typesetting, hot metal, and hot type) is a technology for typesetting text in letterpress printing.
- Check operation and conditions. These tapes could be read and processed by many, maybe most optical setting systems.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Hot metal typesetting transfers literally when a new case preserves the same carrier type, relation, and recognition test. Various methods were used to power the Linotype / Intertype machines, the most common being a fractional horsepower motor, one wired for single-phase 60 Hz alternating current eventually becoming the default offering. The Super-caster, another machine produced by Monotype, was similar in function to the Thompson, Barth, pivotal and other casters but designed to.
