About Graphic File Formats

• Graphic art on this site is offered in multiple formats. GIF and JPG (or JPEG) are suitable formats for web pages, word processing documents, etc. Click on the link to open the file, then use your browser's File, Save menu option to download the image. Or right-click over the link and choose "Save Picture As" (Internet Explorer) or "Save Image As" (Netscape) to download. (Wording of these menu options may vary.)
• PDF, the Adobe Portable Document Format, preserves the look and feel of the original document. For some printing and duplication purposes (classroom use, for example), this is a good choice. To read and print a PDF file, you must have the Adobe® Acrobat® Reader installed on your PC. You can download a version suitable for your system, free of charge, from Adobe. We recommend using the latest version of the Reader. 
  
  Click on the link to open the PDF file, or right-click over the link and choose "Save Target As" (Internet Explorer) or "Save Link As" (Netscape) to download.
• EPS (Encapsulated PostScript) is a higher-resolution format. Files in this format may be too large to fit on a standard floppy disk. We suggest having your printing professional download the files from this site, or saving them to a computer hard drive (space permitting), high-capacity disk (e.g., Zip® or Jaz®), or writable CD. (Note: your system's download manager may show the file extension EPS as PS.)
• Materials are also offered in a high resolution SIT format for professional offset printing. These files were prepared on a Macintosh G3 using programs such as Adobe PageMaker, Quark XPress, Adobe Illustrator, and Adobe Photoshop. To facilitate downloading, the files have been compressed using Aladdin’s Stuffit Deluxe and archived in a .SIT file. To expand or open a .SIT file you will need a copy of Stuffit Expander. You can download a free copy from the Stuffit website at http://www.stuffit.com/. PC users will not be able to open or manipulate the files contained in the .SIT archive files. PC users will need to work directly with a professional printer, graphic designer, or service bureau to open, manipulate, and print the files. File sizes listed on these Web pages are for the compressed files.
