Definitions
- Camera-ready art
Any drawing, photos, illustration or lettering suitable for photographic
reproduction.
- Bitmap (or "raster")
Electronic representation of a page, indicating the position of every
position spot (zero or one). A graphic image or picture portrayed
in pixel. Such as jpgs, gifs, eps, tiffs, picts, psd, bmp, etc…
- Vector
a mathematical defined object(geometrically perfect). Can be resized
or reshaped without diminishing its sharpness or smoothness. Found
in ai, eps, cmx, cdr, dxf,wmf/emf
- Paper Proof
color or black and white artwork printed on paper before printing on
actual product(s).
- Register Marks
Cross-hair marks applied to negatives, artwork, photographs or mechanicals
to ensure precise register on the final product.
- Crop marks
Indicators on artwork to show where an illustration is to be cut or
sized.
- Pantone Matching System (PMS)
Color scale used to precisely match colors for printing. Each hue has
a coded number indicating instructions for mixing inks to achieve
that hue. Available for spot colors and process colors in coated
and uncoated colors. PMS COLOR CHART
- Logo or Logotype
Style of lettering or design of a company used as a trademark to identify
itself.
- Color separation
Separation of multicolored original art by camera or laser-scan techniques
to produce individual separated colors. There are four common separatons:
yellow, magenta, cyan and black.
Vector Artwork Files
Vector artwork files must be written in the
PostscriptTM language. Files can obtain no PostscriptTM errors,
stray points or colors assigned to elements in manner inconsistent
with the supplier's published requirements.
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 the supplier's specified computer platform
(operating system).
Any line thickness must exceed the supplier's
minimum 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 "metafiles".
The artwork file(s) should be accompanied by
a printed proof, or its electronic equivalent, which communicates
to the supplier 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 the supplier's specified minimum.
Unless suppliers specifically request CMYK
files, the color space of images submitted for process color separation
should remain in the native RGB color space to permit suppliers
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 supplier 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 supplier 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.
