Graphics Content Files

Clients who like to design their own publications use various media to create their product.

Graphics files can be particularly problematic. File types are identified by their extensions which are abbreviations of their names and where they originated:

ai-icon                 pdf-icon                 jpg-icon

  •  JPG – Joint Photographic Experts Group
  • PNG – Portable Network Graphics
  •  EPS – Encapsulated PostScript
  • PDF – Portable Document Format
  • PSD – Photoshop Document
  •  AI   –  Adobe Illustrator Artwork
  • GIF – Graphics Interchange Format
  • TIFF – Tag Image File Format
  • SVG – Scalable Vector Graphics

Basically, there are two terms to keep in mind:

  • Raster Graphics – for a complete definition click here
  • Vector Graphics – for a complete definition click here

Some snippets from this post:    “Vector files are an absolute must.”


This is the file format most often requested by print shops. The PDF reigns king as a vector file format.

Note: the PDF has to be saved from a vector program to be a true vector PDF. If you save a PDF from Photoshop (and they aren’t vector shapes), it will still get pixelated when it hits the print shop.

Understanding the difference between vector files and raster or bitmap files will help enormously in creating superior art work to be sent to the print shop.
