Full Title

Full titles differ between systems:

IPC:

Holographic processes or apparatus using light, infrared, or ultraviolet waves for obtaining holograms or for obtaining an image from them; Details peculiar thereto > Processes or apparatus specially adapted to produce multiple holograms or to obtain images from them, e.g. multicolour technique

CPC:

Holographic processes or apparatus using light, infrared or ultraviolet waves for obtaining holograms or for obtaining an image from them; Details peculiar thereto > Processes or apparatus specially adapted to produce multiple holograms or to obtain images from them, e.g. multicolour technique

CPC subdivides this area 3x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.
