Optical Brightening Agents (OBAs) are used in many paper mills and premium inkjet paper manufacturers to make a yellowish paper appear whiter and brighter. Until recently, color management technologies have not been able to deal with the color variations these OBAs cause in custom ICC output profiles – a problem for users in color-critical proofing and printing environments.
X-Rite’s Optical Brightening Compensation (OBC) solution helps compensate for these color shifts, so the color you measure with your color management device is the same color you see in a viewing booth. It’s designed for use in conjunction with X-Rite's i1iSis family of automatic spectral chart readers and ProfileMaker or MonacoPROFILER profiling software.
X-Rite's OBC solution is now included with every i1iSis device. If your device was purchased before August 2008, the OBC Module is available as a separate purchase.
