Tech Note 4018 6/30/94) Adobe Illustrator TM - Macintosh ®

If you enter text in Adobe IllustratorTM and you see no characters on the screen or vertical lines

instead of characters, you are most likely encountering a conflict between Adobe PostScriptTM

and Apple® TrueTypeTM fonts. Another related problem you may encounter is an inability to create outlines from text.

BACKGROUND

TrueType is scaleable font technology that is a feature of System 7TM. Apple s TrueType works

in much the same manner as Adobe Type ManagerTM and PostScript Type 1 fonts. The system soft-ware scales an outline of a specific letter to the size needed and then fills it in with pixels for display on screen, resulting in smooth characters at any point size. When you install System 7, the Apple Installer automatically loads TrueType outline fonts and corresponding bitmapped fonts for Chicago, Courier, Geneva, Helvetica, Monaco, New York, Symbol and Times. System
7.1 users will also receive Palatino in TrueType format.

Adobe Illustrator, versions 3.x can create outlines only from PostScript Type1 fonts. Version 3.2 can make limited use of TrueType fonts, but only for displaying plain text. Version 5.x can create outlines from both PostScript and TrueType fonts but note the limitation at the end of this para- graph. Versions 3.x ship with the "base thirteen" Type 1 typefaces (in the families of Courier, Helvetica, Symbol and Times) while Version 5.0 ships with forty typefaces (the "base thirteen" and twenty-seven additional)and 5.5 has the base thirteen and 180 additional fonts. While you can have both PostScript and TrueType fonts on your system, for Adobe Illustrator (all versions) to display and use fonts correctly, it is essential that you do not have both formats for the same font family.

Because Adobe Illustrator and the System 7 installer both provide fonts (in PostScript and TrueType formats respectively) for Courier, Helvetica, Symbol and Times, you should remove the TrueType versions of these typefaces and make sure you have only the PostScript versions installed. The remainder of this Tech Note discusses how to do this. Because the many combinations of the different versions of Adobe Illustrator and System 7 necessitate different installation steps, this Note may initially appear rather lengthy and complex. Don t worry, just follow the steps appropriate to your situation and things should go smoothly. TrueType TM Conflicts
