The following general instructions are for authors using graphics packages for the creation of electronic graphics and should be passed on to others preparing graphics for authors. Submit files for graphics as EPS files. This includes graphics originated via a graphics application as well as scanned photographs or other computer-generated images. If this is not possible, TIFF files are acceptable as long as they can be opened in Adobe Photoshop or Illustrator. Use line weights of at least 0.5pt after any scaling.
Hairlines often look acceptable when proofed on a typical laser printer.
However, when produced on a high-resolution laser imagesetter, hairlines become nearly invisible and will be lost entirely in the final printing process. Use Type 1 outline fonts instead of bitmap fonts whenever possible. If submitting bitmap graphics, submit them at a resolution of at least 600 dpi. Text set in a bitmap font generated for a 600 dpi laser printer might look crisp when printed from a 600 dpi laser printer, but when the same text is imaged on a 1200 dpi imagesetter, it might have jagged edges. Avoid fonts with city names such as Chicago, Monaco, Geneva, etc.
