Therefore, do not use the fonts that come with a MAC system - these are all TrueType fonts. Font manufacturers must be known before a job can be processed. A printer font must be submitted for every attribute, i.e., italic, bold, bold-italic, outline, etc. If these attributes are applied to a font, and no PostScript printer font is available for the attribute, the type will revert back to the original font during imaging. Do not apply a bold attribute with the expectation that it will output to film as you see it on your computer monitor.
Problems also occur if printer fonts are missing.
We can cite a case when San Gothic Serif was used with an italic attribute. When processing the film, it was discovered that a printer font for an italic attribute for this font does not exist. The only way to output this job was to create single page negatives generated from application files instead of fully imposed film flats generated from PostScript files. This caused delays and additional production costs. In order to generate imposed film flats, the files must be in a PostScript or PDF format.
