Camera-ready is a common term used in the commercial printing industry meaning that a document is, from a technical standpoint, ready to "go to press", or be printed.
History
The term camera-ready was first used in the photo

Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on t ...

". Then, a
stat camera was used to photograph the mechanical, and the final offset printing plates were created from the camera's negative.
In this system, a final paste-up that needed no further changes or additions was ready to be photographed by the process camera and subsequently printed. This final document was ''camera-ready''.
This artwork may have looked messy to the naked eye or to a modern consumer digital camera - covered in various pieces of paper attached with adhesive or wax and composited with white out, gouache, tape and blue pencil (non-reproducible) and red masking film, black or clay-based paint (reproducible as black) - but appeared perfectly uniform to the monochrome reproducing camera used for print reproduction.
Present usage
In recent years, the use of paste-ups has been steadily replaced by
desktop publishing
Desktop publishing (DTP) is the creation of documents using page layout software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online c ...
software, which allows users to create entire document layouts on the computer. In the meantime, many printers now use technology to take these digital files and create printing plates from them without use of a camera and negative. Despite this, the term ''camera-ready'' continues to be used to signify that a document is ready to be made into a printing plate.
In this new digital-to-plate system, a digital file is usually considered ''camera-ready'' if it meets several conditions:

# The layout is created at the correct and final size to be printed, and the document size in the desktop publishing program matches the size of the final printed piece.
# Text or graphics that are intended to
bleed off the page of the final printed piece should be extended off the document boundary in the digital file. The amount varies depending on location, but is usually 1/8 inch in the US, and 3mm in metric systems.

(usually defined by the software as "convert to paths" or "outline text"), or alternatively, the fonts are included in the final digital package sent to the printer. The inclusion of fonts in this way is called "embedding". Be sure to embed your fonts if possible. Some fonts cannot be embedded due to copyright or usage rights.
