effect. They detect these brighteners as far more blue than they appear
to our eye and the results are profiles that, although accuracy measured,
produce a decidedly blue colorcast. There are two ways to counter these
phenomena. One is to place a UV filter over the Spectrophotometer, to
filter out the optical brighteners. This option exists with the Spectrolino
and DTP-41 and other instruments discussed earlier.
But many Spectrophotometers have no means of attaching an
optional UV filter. Some Spectrophotometers ship with this filter in place
but the filter can't be removed. These units usually cost more then their
non-UV cousins. The other option is to detect the presence of the optical
brighteners in the software that builds the ICC profile and compensate
for this effect. The software solution makes sense and works very well at
compensating for the effect of these optical brighteners. GretagMacbeth's
ProfileMaker Pro and Eye-One Match detect and compensate for optical
brighteners and do an excellent job easily on par, if not better, than using
a UV filter on the Spectrophotometer. The compensation is always in
effect with Eye-One Match, and ProfileMaker Pro indicates the presence
