The Lud­low Typo­graph — more com­monly ​‘the Lud­low’ — is a machine that com­bines hand assem­bly of each char­ac­ter, along with the cast­ing of brand-new type for each line.  The oth­er type found­ing machines used by print­ers were dri­ven by a key­board: the Linotype/Intertype machines hav­ing the key­board built-in; and the Mono­type using a key­board to punch paper tape.

The prin­ciples behind the Lud­low are sim­ple — the oper­ator col­lects a small brass mould for each char­ac­ter need­ed in the line.  These are assem­bled into a ​‘stick’, a small frame, and the moulds are clamped togeth­er to form a line of moulds.  This stick and moulds are then clamped in to a machine which injects hot met­al into the moulds.  A line of type is cast and ejec­ted from the front of the machine.  The moulds have to be dis­trib­uted back into the rel­ev­ant cas­es by hand.

Unusu­ally, the Lud­low can cast between 6pt and 228pt type on slugs with­out changes to the machine.  Oth­er sys­tems have to be mod­i­fied with each size change.

The Lud­low was typ­ic­ally used in two spheres: the news­pa­per and the rub­ber stamp indus­try.  News­pa­pers typ­ic­ally used the Lud­low to pro­duce head­lines to sit with their Inter­type or Lino­type mat­ter.  Rub­ber stamp mak­ers use the machines to pro­duce the ori­gin­als for stamps.
