Native program formats, with the exception of Photoshop, are to be avoided. Impressions would be happy to provide more information about the usability of specific file formats. In addition to scanned or otherwise bitmapped images, artwork can be created in vector form from scientific or illustration programs. Both of these formats are written in a standard, platform-independent page description language that requires little translation for use in page layout programs. Not all such files will work, but EPS and PostScript are by far the most reliable formats for art submission.
Conversion is frequently time-consuming and expensive.
WordPerfect and Microsoft Word both have resident drawing programs. These, along with Excel, Harvard Graphics, and other similar programs do not produce usable electronic art. All fonts used in electronic files must be included on disk with the submission. We must have the correct fonts in case any changes are needed, and we must make sure the ultimate printer has the correct fonts or your graphics will not print properly. It's important to provide a clean hard copy against which we can check for text reflow and other peculiarities.
