Graphics or Links
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
- Raster images consist of non-scalable pixels or dots that will blur when enlarged too much and can appear grainy or blurry on press.
- Vector graphics consist of actual mathematical line formulas that can be scaled without loosing any clarity.
With raster image resolution at 72, the pixels that make up the image are easily viewable.
Vector Images provide a resolution independent graphic that can be scaled to any size and remain clean and crisp in appearance.
Raster Image Wrong Resolution
If the Image resolutions is altered to make it a higher resolution it will make the image appear blurry because there was not enough information in the file to properly scale the pixels up.
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.
PPI vs DPI
- PPI or Pixels Per Inch is used to measure the number of squares (pixels) per linear inch on screen that the image holds. These pixels are converted in-house by the printer to dots for reproduction purposes. The PPI measurement can be the same as DPI but is always recommended to be 300ppi for high quality commercial print.
- DPI or Dots Per Inch is typically used to describe the number of physical dots per linear inch put down by the printer on the printed piece. This amount of Press Dots printed per linear inch is controlled in-house by the printer. These press dots create the illusion of the intended colors with only 4 inks being used. The dots are also limited by the equipment the project will be reproduced on. The DPI measurement is anywhere from 300dpi to 1200dpi, although on most projects, 300dpi is recommended for best quality.
