The traditional standard for acceptable mechanical artwork is "camera-ready black and white" material. Typically, anything of a lesser quality may be subject to extra charges.
Vector Artwork Files
Vector artwork files must be written in the PostscriptTM language.
Any type set on paths must be converted to Postscript outlines (curves). If additional or future typesetting is anticipated or type left unconverted, the font files must also be supplied for use on specified computer platform (operating system).
Any line thickness must exceed minimum imprint size when the artwork is scaled to the actual imprint size. Files with any placed, parsed or linked elements require certain additional criteria described in the standard for "meta-files".
The artwork file(s) should be accompanied by a printed proof, or its electronic equivalent, which communicates the the desired result of the use of the e-artwork file(s).
Bitmap Artwork Files
Bitmap files should render images at 100 percent of actual imprint size.
Images that contain halftones, tints, grayscales or are intended for process color separation should have a bitmap resolution (pixels-per-inch) that is a multiple of no less than 150 to 200 percent of the line screen frequency specified by the printing process.
Images that contain line art or areas of solid color should have a bitmap resolution (pixels-per-inch) of no less than specified minimums.
Unless specifically requested as CMYK files, the color space of images submitted for process color separation should remain in the native RGB color space to permit Production to apply their own separation setup preferences.
Page Layout Documents
Page layout documents must be prepared to render artwork and/or other elements to be printed at a scale of 100 percent of the actual imprint size.
In addition to submitting the page layout document(s), there must also be the submission of all vector and/or bitmap files that are referenced by the page layout document.
The font files and document preferences necessary to properly render any text in the page layout file must also be supplied for use on the supplier's specified computer platform (operating system).
The page layout file(s) should be accompanied by a printed proof, or its electronic equivalent, which communicates to the Production the desired result of the use of the page layout file(s).
Acrobat (PDF) Files
PDF files created from vector files must be suitable for reverse-conversion to vector files or to use in the PDF format such that the file meets the quality standard for vector files.
PDF files created from bitmap files must be suitable for reverse-conversion to bitmap files or for use in the PDF format such that the file meets the quality standard for bitmap files.
PDF files created from metafiles or page layout documents must be submitted together with the source document, all fonts and imported graphic components unless the Production specifically waives these requirements.
PDF files are acceptable as proofs (both for submission of the order to the supplier and pre-production examination by the distributor) subject to the limitations of the Adobe PDF file format and any other limitations published by the supplier.
Other Than Above
Unless digital files satisfy the readiness standards for vector files, bitmap files, metafiles, page layout files or PDF files - or they are otherwise specified as acceptable - those digital files DO NOT meet the readiness standards for e-artwork
