Printing Terminology: Proofs

Mock-up of a proofs for print jobs ranging from a business card to a postcard to a business form.

In our last post discussing the PDF file format, we mentioned the term proof. But what exactly is a proof? A proof is a preview of how a document will appear when printed. Proofs enable a customer to do a final check before the piece goes to press to ensure all the necessary aspects are in order. In particular, for any documents containing text, it’s critical to check for spelling errors, typos, etc. Proofs are intended as the final fail-safe before going to press so as to avoid costly reprints.

Two Kinds of Proofs: Soft Proofs and Hard Proofs

The most common proof provided to clients for standard print jobs is a PDF file sent via email or downloaded from a website and intended to be viewed on a computer screen. Proofs that exist in the digital realm are known as soft proofs. These proofs are easy to create, are usually provided free-of charge, and expedite the printing process.

For more complex projects, a physical sample of the printed piece may be desirable. Known as a hard proof, a physical sample can demonstrate how certain processes—that can’t be conveyed or displayed in a digital proof—will appear in the final printed piece. For example, pieces requiring unique folds, die cuts, foil-stamping, embossing, specialty inks or precise color-matching, are often produced as a physical sample before the job goes into full production.

Additional Costs

While most soft proofs are provided free-of-charge, hard proofs may incur fees. Generally, these costs are determined and assessed by consultations between the client and the printer at the beginning of a project. It is also not uncommon for some clients to pay for an initial press run (say 50 pieces) of a piece before committing to the full production run.
