i1iSis Optical Brightener Compensation (OBC) Module - User Guide

6. Building ICC Profiles with OBC Data

Using Optical Brightener Compensated Data in X-Rite ProfileMaker

Software

Select the Printer tab, then drag and drop your ProfileMarker Session text file into the reference 1.

window. This will automatically place the proper data into the Reference and Measurement Data

fields. Reset the reference data set to ECI2002 in the reference window.

Set up the profile options as you normally would for the type of printer or press that you are 2.

using.

If you are working with a CMYK printer, you can also set your separation settings to match your 3.

printer or press conditions

Please note that due to a known bug in ProflieMaker 5, the software won't allow more than

320% TAC when the OBC Measurement Data is imported via drag and drop. Please reset the

reference data set to ECI2002 in the reference window after importing the data. After the reset

ProfileMaker will allow up to 400% TAC.

Please do not check the 'Correct for Optical Brightener' box in ProfileMaker to avoid double

compensation. Usually the box should be grayed-out for OBC data, but under some circumstances

ProfileMaker will allow another compensation with the existing, more simple optical brightener

correction algorithm. A second compensation will lead to poor quality of the generated ICC

profile.

To get optimal results for the perceptual rendering intent with the OBC Module, please choose

‘Paper colored Grey’ in the Perceptual Rendering Intent menu.
