Problem: PostScript Level 1 versus PostScript Level 2
Solution or Workaround
What is the difference between Level 1 and Level 2 PostScript?
PostScript Level 2 includes all of the features of Level 1, plus additional features such as data compression modes for smaller files, support for CIE-XYZ device independent color, ATM font rendering, performance improvements, forms, patterns, and improved half-toning features.
CIE-XYZ is a color standard which generates color that is designed to be
independent of the technology or printer being used. However, using this feature requires support from the application software.
