i1iSis Optical Brightener Compensation (OBC) Module - User Guide

Please note that the validation of a proof based on an OBC-ICC profile might fail even though the

quality of the hardcopy proof is good when measured with a NoFilter spectrophotometer like the

i1Pro, as measurements from this type of device do not correct for the optical brightening agents

in the paper. If applied correctly, OBC profiles will produce better visual agreement between

hardcopy and softcopy proofs and prints. As the OBC Module creates a new group of

measurement conditions taking the optical brightening agents and the amount of UV of the

viewing condition into account, different OBC conditions such as NoFilter and UVcut Filter

measurements should not compared against each other.
