There are usually two types of fonts. Truetype and Postscript Fonts. The quality of type faces and fonts varies greatly from foundry to foundry. Truetype, while simpler to install, usually are cheaper to produce, and while may look okay on screen may print differently. You get what you pay for when using these types of packages and quality may suffer.
Postscript fonts are higher quality true imaging fonts.
While more expensive, they deliver predictable results to high end printers such as ours. It is always recommended to use Postscript fonts. Most high end applications allow you the choice of linking to the photos and graphics you insert into your document, or embedding them into the main document. Linking is always the preferred method. When you link files, your main document remains smaller in size and more manageable.
