A digital proof is a color prepress proofing method where a job is printed from the digital file using inkjet, color laser, dye sublimation, or thermal wax print technologies to give a good approximation of what the final printed piece will look like. The digital proof is generally less expensive than other prepress proofs. Digital proofs can often be produced on the actual paper stock of the job adding another element of accuracy.
Digital proofing also includes a type of almost-WYSIWYG on-screen monitor proofing or soft proofing generally only used in the early stages of production.
Digital proofs come in continuous tone and halftone proofs. Strides in color technology increasingly allow some digital proofs to serve as contract proofs.
