Title

Titles differ between systems:

IPC: Exposure; Apparatus therefor

CPC: Exposure; Apparatus therefor (photographic printing apparatus for making copies G03B27/00)

Full Title

Full titles differ between systems:

IPC:

Photomechanical, e.g. photolithographic, production of textured or patterned surfaces, e.g. printed surfaces; Materials therefor, e.g. comprising photoresists; Apparatus specially adapted therefor > Exposure; Apparatus therefor

CPC:

Photomechanical, e.g. photolithographic, production of textured or patterned surfaces, e.g. printing surfaces; Materials therefor, e.g. comprising photoresists; Apparatus specially adapted therefor (using photoresist structures for special production processes, see the relevant places, e.g. B44C, H10P76/00, H05K) > Exposure; Apparatus therefor (photographic printing apparatus for making copies G03B27/00)

CPC subdivides this area 3x more granularly than IPC with 8 additional codes.

8 codes are CPC-only extensions, 1 exist only in IPC.
