foundry proof
Noun: A foundry proof is a specific type of proof, or trial impression, taken from a composed form of type or printing plates before duplicate plates (such as stereotypes or electrolytes) are created for the actual print run. It serves as the final check for accuracy and quality before mass production.
The term is used almost exclusively in the specialized context of traditional printing and typography. It refers to a physical artifact—a printed sheet—used for verification. - The printer examined the foundry proof carefully for any errors before authorizing the creation of the duplicate plates. - Any corrections marked on the foundry proof must be made to the original form before plating.
- In historical printing contexts, the foundry proof was a critical step, as creating duplicate plates was expensive and time-consuming. Catching errors at this stage prevented significant waste.
- The phrase "pull a foundry proof" describes the action of creating this proof.
- After the final corrections, they will pull a foundry proof for the client's approval.
- Proof (n): A general term for a trial impression taken from type, plates, or blocks to be checked for errors. A foundry proof is a specific type of proof.
- Galley proof (n): An earlier proof, typically taken from a long tray (a galley) holding composed type, before the type is arranged into pages.
- Page proof (n): A proof of typeset material after it has been arranged into pages, but often before final plating.
- Final proof (in the context of pre-plate verification)
- Pre-plate proof
This term is highly technical and historical. With the dominance of digital printing, the process of creating foundry proofs is largely obsolete. The term is now primarily encountered in discussions of printing history, bibliography, or the preservation of antique printing methods.
