6.1.13 Profile ID

Profile ID is generated by using the MD5 fingerprinting method
(details of which can be found via the Technical Notes page on the ICC
web-site - www.color.org).. The entire profile, based on the size
field in the header, is used to calculate the ID with the exception of
the Rendering intent, Header attributes, and Profile ID fields in the
profile header for which zeros are used instead of their actual
values. A Profile ID value of zero indicates the ID has not been
calculated. However, it is strongly recommended that profile creators
do calculate and fill in the correct value in the Profile ID field.
