Thomas,
I think that Level 1 supports only gray, while Level 2 supports color, but
there is also a "Level 1.5" middle ground with Level 1 plus a limited number of
color operators that color printers used before Level 2 was adopted.  "pdftops
-level1sep" generates only the "Level 1.5" color operators.  Software color
separation usually supports only the simpler "Level 1.5" color operators.  That
is why I need -level1sep to work, and to run quickly on large files.  ("large"
is several hundred MB for a graphic the size of a broadsheet newspaper page
with embedded high resolution color images, like an ad for a car dealer.)
William
