Definition of Proof:

  1. Make (fabric) waterproof.

  2. A test or trial of something.

  3. General: Evidence that establishes existence or truth (or non-existence or untruth) of a fact to the satisfaction of an authority (such as a court) or according to the accepted standards.

  4. Law: Evidence on which the determination of the judgment of a court case is based. Unlike a mathematical-proof (based on logical evidence) or scientific proof (based on empirical evidence), a legal proof is based on the credibility of a document or witness.

  5. Alcohol: US measure of the volume of alcohol (ethanol) in an alcohol-water mixture, expressed as degree proof (° proof). One degree proof equals one-half of a percentage. Thus, 80 proof means 40 percent alcohol, and 200° proof means 100 percent alcohol.

  6. Denoting a trial impression of a page or printed work.

  7. Activate (yeast) by the addition of liquid.

  8. Make a proof of (a printed work, engraving, etc.).

  9. The strength of distilled alcoholic liquor, relative to proof spirit taken as a standard of 100.

  10. Evidence or argument establishing or helping to establish a fact or the truth of a statement.

  11. A trial impression of a page, taken from type or film and used for making corrections before final printing.

  12. Able to withstand something damaging; resistant.

  13. Printing: Test sheets of a page or print job taken out at each stage a document passes through during the printing process. Page-proofs are sent to the client or author to check (called proof reading) for any errors in spelling or punctuation; and color proofs are meant to ensure that the final print matches an artwork or sample. A corrected or approved proof is a type of contract under which the client is responsible for any errors undetected in the signed proof, and the printer is responsible for errors that are pointed out but not corrected, or for errors that occur after customers OK.
