Digital Proofing--Proof Positive

Not all proofing technologies can accomplish all three functions. Basically, proofs fall into two categories, conventional and digital.

Conventional Proofs: These can be either press proofs (made on-press) or off-press proofs (often referred to as analog proofs). Conventional proofs are made from film and represent the screening, dot shape and other parameters of the job. Products such as the Imation Matchprint, DuPont WaterProof and Fuji Color-Art have become widely used as contract color verification methods for most high-quality graphic arts applications. Press proofs are still used in advertising, where proofing on the printing stock and large quantities are important elements.
