Constants for PostScript Data Formats
The ColorSync Manager provides the following constant declarations to specify the format of PostScript data.
enum {
   cmPS7bit = 1,  /* data is 7-bit safe */
   cmPS8bit = 2   /* data is 8-bit safe */
};
Enumerator descriptions
cmPS7bit
The data is 7-bit safe--therefore the data could be in 7-bit ASCII encoding or in ASCII base-85 encoding.
cmPS8bit
