Saving Graphics for a Desired Output

Helpful hints as to what file format you should save your graphics in depending on what you want to achieve.

If final output is...	Do this...
High resolution output (over 800 dpi), PS (Post Script)	use EPS for vector graphics, TIFF for bitmap graphics, both support precision output for text and graphics at high resolutions
Process-color separations	use EPS for vector graphics, CMYK TIFF of DCS EPS for color bitmaps, and TIFF for grayscale bitmaps. These file formats support high-resolution output devices and consistent CMYK color
PDF (Portable Document Format)	any compatible file format is ok. EPS or TIFF graphic is likely to print most consistently, though, since final output is on screen - low resolution graphics
low-resolution PS printer	any compatible file format is ok EPS or TIFF likely to print most consistently
non PS printer	use any compatible file format, though avoid graphic effects that require PS printer
Slide Recorder (ie LFR)	if slide recorder supports PS, import an EPS graphic. Otherwise, use nonPS format and avoid effects that are nonPS-compatible. You can also save in PICT if the document does not contain rotated or distorted text, or embedded EPS graphics, or when all fonts are either in TrueType or AdobeType Manager (if installed). Otherwise, you can generate a PostScript file (via LaserWriter Driver).
