i1iSis Optical Brightener Compensation (OBC) Module - User Guide The information from both measurements is used by the OBC Module to correct for the optical brightening agents in the substrate. As the level of correction must be adjusted to the intensity of the effect of the optical brightening agents in a real-world viewing situation, the amount of UV light in the viewing condition must be assessed as an additional step.

i1iSis Optical Brightener Compensation (OBC) Module - User Guide Printing a CMYK Test Chart from RIP Software When profiling a printer through a RIP, you will need to select a CMYK target. You will need to perform any media calibration routines provided by the RIP software. 1. Calibrate the media for the print settings that you will use when printing in normal production. These settings include screening, resolution, and any other settings that affect the way that ink or toner is placed on the substrate.

Use the exact same settings that were used to print the previous test chart. 8. Open the Optical Brightener Compensation Standards envelope and carefully pull out the set of sheets that matches the gloss selection you made earlier (high gloss or matte). 9. Use the same viewing conditions that you intend to use to view you prints (eg: a light booth).
i1iSis Optical Brightener Compensation (OBC) Module - User Guide 10. Once you have made the best selection, record the values in the OBC Module. After this is completed, click the right arrow to continue. i Please note that for low amounts of optical brightening agents in the substrate, the color deviation between the patches can become negligible. When lower amounts of OBAs exists, the accuracy of your choice becomes less important.

Building ICC Profiles with OBC Data Using Optical Brightener Compensated Data in X-Rite ProfileMaker Software 1. i 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. 2.

i1iSis Optical Brightener Compensation (OBC) Module - User Guide i 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.
