The most well-known of the HandShake formats is Scitex CT (continuous tone).
This format may store from 1 to 16 8-bit color separations (color planes).
Typical CT files store four separation of CMYB image data. Adobe Photoshop
is an application that is commonly used to create Scitex CT image files.

The other HandShake formats include LW (linework, 16 color separations, 255
color maximum), BM (bitmap, 1-bit RLE image data), PG (page layout), and TX
(textual typesetter data). Of these formats, PG and BM have not been fully
implemented by Scitex and may not be in general use elsewhere.
