Hi,

Argyll uses RGB values in it's ti2 files for printer profiling:

SAMPLE_ID SAMPLE_LOC RGB_R RGB_G RGB_B XYZ_X XYZ_Y XYZ_Z
29 "B12" 22.745 18.431 73.333 12.622 7.4458 48.192

Say I have some XYZ or LAB values, how can I compute the proper RGB values?
the XYZ values in ti2 files are estimated and only intended for validation purposes. Why do you want to transform them to RGB? 

see
<file:///Applications/argyll/Argyll_V1.1.0_RC1/doc/File_Formats.html#.ti2>


And is there an easy way to do this for larger data sets?
you can use icclu, xicclu or fakeread to transform colors from/to different colorspaces.
