Profile File Sizes - Why so Different?
« on: January 26, 2013, 03:17:44 PM »

I have about 50 profiles installed on my PC.  Some are .icc, some .icm, and a few other types. The file sizes range from 1KB to 1,637KB.  Why such a big difference?

There are simple matrix based profiles that contain just a few data points and then there are table based profiles that contain a bunch of tables full of data that more precisely define the irregular characteristics of a device and how conversions are to be handled for each intent. Table based profiles can be made in various resolutions (larger or smaller tables) which also effects file size...
