What is a galley proof?

In publishing, a galley proof is considered the last chance for the author, editors, and proofreaders to make the final edits to a book. This stage is not meant for major content changes, but rather minor edits.

The name “galley proof” comes from the days of hand-set letterpress printing in the 1650’s. In this time, the pressman would set the type in metal trays and lay out the pagination. The book printer would produce printed sheets of paper on a small press, which was used for proofing before placing it on the larger press.

In today’s publishing world, a galley proof is typically reviewed electronically during the final editing stages by editors, authors, and proofreaders. Once it receives final approval, the next step is to start the proofing stage with the book printer.

There are many terms for a “galley proof” used in proofing terminology: blue print, page proof, press proof, soft proof, hard proof, electronic proof.  Communicating what type of proof the printer provides is essential for the publisher to understand what they will receive during this phase.

Here are brief descriptions of the many types of proofing:

Blue Print:  Back in the day, this proof was called an Ozalid. The ink on the proof is blue and white. These are mostly used in newspaper print or magazine print for quick reference. Typically blue prints are not used for book printing.

Page Proof: This terminology is the same a galley proof, reviewing online or on paper before the plates are made for printing.

Electronic/Soft Proof: This proof is used for reviewing the final book content as a PDF file for confirmation before printing and plates are created.

Hard Proof: Paper proof created on a digital printer. If the printer prints with a digital press, this will be almost 98% color accurate output to paper. If the book project is produced through offset printing, the digital proof is 80-90% color accurate.

At PRC Book Printing we offer offset book printing services. We have a selection of proofing options.  Some clients need their proofing 99% color accurate, for which we can suggest a press proof route.  This type of proofing is extremely expensive, due to creating plates and cost of make-readies. PRC will find solutions for the proofing you require to fit the book project.

If you are seeking a hardcover photography book or a coffee table book needing color accuracy, call PRC Book Printing today 888.659.8320 or email at info@prcbookprinting.com . We will find a solution aimed at your offset book printing needs.
