POSTSCRIPT

Type 1 fonts

Type 1 fonts are base fonts with character shapes defined by using specially encoded PostScript procedures. Because characters are drawn by PostScript procedures, many visual elements that are not associated with fonts can be represented as characters in a Type 1 font.

The multiple master font format is an extension of the Adobe Type 1 font format and is supported by DocuPrint NPS.

Refer to the Adobe PostScript Language Reference Manual for more information, and the Adobe Type 1 Font Format document for encoding information.

Type 1 fonts are available on DOS formatted diskettes and can be loaded on the DocuPrint system using the font installation utility.

According to the Adobe Type 1 Font Format, a conforming Type 1 font program contains the following first line:

%! FontType1 - SpecVersion. Font Name FontVersion

SpecVersion is the version of the Adobe Type 1 Font format to which the font program conforms.

FontName is the name of the font understood by the PostScript interpreter.

FontVersion is the version number of the font program.

The first line of the Type 1 font, which is available by reading the header of the Type 1 font program, can aid in determining differences between fonts on PostScript devices.

Using Adobe Type 1 fonts

One of the factors that can negatively impact performance on DocuPrint NPS is the use of small graphic images, logos, and signatures embedded in PostScript masters. When these graphic items are used on each page of a document, DocuPrint performance can be slowed down.

The Type 1 font capabilities of DocuPrint can handle commonly referenced, small or large graphic elements such as logos and signatures. You can install and remove any Adobe Type 1 font from a DocuPrint system using standard administrator commands in the DocuPrint Printer Controller. Fonts used only occasionally for a single job can be included in the PostScript master for the jobs that require them.

Caution: Type 1 fonts should not be downloaded with a PostScript file because printer performance will be degraded significantly. Instead, use the Install Fonts From Floppy or CDROM command, and then reference the font in the PostScript file.

Using fonts for small graphic elements has the following advantages over using referenced content files:

•You do not need to perform the NFS setup required for referenced content files. DocuPrint can be used in a standard configuration.

•Visual elements stored as fonts can be easily rotated and scaled.
