The mathematical model implied by this data is connection = grayTRC[device].
This represents a simple tone reproduction curve adequate for most monochrome input
devices. The connection values in this equation should represent the achromatic
channel of the profile connection space. If the inverse of this is desired, then the
following equation is used, device = grayTRC −1 connection [ ].
Multidimensional tables are not allowed to be included in monochrome profiles.
