Graphics or Links is any artwork element that is used in the document that may need to be sent with the native files. Save all elements in CMYK color mode not RGB, colors on screen will shift somewhat in the conversion (e.g. blue on screen will be bright blue but when converted to CMYK it will be more dull and may turn to purple.) The Pantone book will provide several colors that are achievable in CMYK and will give you a good reference of what the final print will look like. (See Color Setup for more information.)
Resources is another name for all graphics files and fonts that are used in original layout program. These images, links and fonts should be included with native files. (e.g. InDesign, Quark) If files are not included low res screen shots will be included in document, and most likely we will be contacting you about low quality.
Image Types or artwork elements that are pictures, drawings, backgrounds or logos used throughout a project that are not text. These images can be two types of basic illustrations. They can be two types of files Raster (photos) or Vector (scalable line drawings)
Raster vs Vector
All “raster” images need to be provided at a minimum of 300 ppi/dpi for good print quality on final project. Make sure that Raster Effects that may have been used in an Illustrator file also be set to 300 dpi. Although PPI and DPI are related they are referring to different ways to measure aspects of the image provided. (Pixels Per Inch or Dots Per Inch) Both terms are somewhat interchangeable and commonly used in the print industry to reference the amount of information an image holds. The higher the resolution the better the quality of the final piece.
