Some page layout programs and many prepress service providers and printers cannot produce acceptable results if you use True Type or specialized fonts. Most recommend Postscript Type 1 fonts for the best output results.
Select typestyles from the font menu instead of using a “style” command. When using bold, bold italic, outline, etc. select the actual typeface from the font menu that is “Times Roman Bold Italic.” Don’t use quick keys or the B,I,etc., style commands on your font bar. The imagesetter may not be able to translate such commands.
Avoid type smaller than 6 point, especially serif typefaces. Thin parts of small serif type characters can disappear when output at high resolution making text difficult to read. Type smaller than 10 point can’t be read easily by most people.
For readability, keep line length between 32 and 62 characters long. Long paragraphs also discourage reading. It is wise to keep paragraphs no longer than six to eight lines.
Using two spaces after a period at the end of a sentence is a holdover from the typewriter era. There is no reason to continue this habit when using proportional digital type. (And believe me it is a hard habit to break!)
Type in color may look good, but is always harder to read than black type. Also, reverse type nearly always decreases readability.
Keep use of exotic or eccentric type, script type, and many sans serif typefaces to headlines and large areas. These typefaces are less easy to read than serif typefaces.
As the last step prior to taking your file to your printer, convert type to a graphic or outlines in EPS files. This will minimize output errors and prevent font substitution. Remember: If type edits are needed later, converted type is now art and no longer a font.
