Change the Font TrueType™ Some output devices are incapable of correctly handling TrueType™ fonts. Furthermore, it is a generally accepted fact that mixing fonts on a page (using Type 1 along with TrueType™) can cause some unexpected results. In this case, it is advisable to switch to a different font, or stick to one single type. City/System Font Most fonts which happened to be named after cities, such as Geneva or Chicago, etc., as well as fonts reserved for System use, such as Charcoal, are commonly bitmap fonts which have no equivalent printers and usually print at a fairly lowly quality and should therefore be avoided. Multiple Masters Multiple Masters technology allows for fonts to literally be created "on the fly", especially when they are missing. In this case, when it is time to print, there may not be any guarantee that the exact same font used to create the document at home or in the office will be used at the print shop, and therefore it is recommended that one avoid using Multiple Masters type fonts. Non-Adobe® Fonts With all due respect for other font manufacturers, many of whom create very high quality and fine-looking fonts, it is sometimes a common practive of professional designers to commit to using only offical Adobe® fonts to ensure output compatibility. It is a known fact that mixing various types of fonts on a page can lead to unwanted or unexpected output problems. These kinds of issues can be avoided by sticking to a policy of creating a document using only certain approved fonts (this is often referred to as "corporation fonts"). Non-Standard Encoding FLIGHTCHECK® will warn you when the font is using a non-Standard Mac Encoding. Unused Style Sheets Unused Styles Sheets which reference fonts that are not active in your System will force the application which created the document to alert you whenever you attempt to open the document. Such missing fonts, of course, do not affect printing, but the alert can be somewhat alarming. In this case, simply remove the unused Style Sheets. FLIGHTCHECK® will warn you when you have unused Style Sheets which reference missing fonts by adding a red asterisk "*" to the Views menu item "Show Styles/H&Js...". Proper usage of fonts is a key factor in creating good-looking documents that successfully print. Over abundance of fonts, mixing types and faces at will, kerning and tracking text randomly, can not only cause a document to look poorly, but can add unneeded processing time to getting the job through the press.
