For a whitepoint other than D50, a Bradford chroma-
tic adaptation is activated by default. Additionally,
XYZ-scaling (reverse vonKries), vonKries, CAT02 and
LMS are also available.
Profile Test
To evaluate the precision of the calibration and profi-
le, iColor Display offers a set of test features.
Notice: Necessarily perform the evaluation right after
saving the profile to make sure that the instrument
has neither changed its position on the screen nor
remains on the screen for too long and got warmed
up (temperature influences precision).
Profile Test
Place the measurement device on the measurement
window (if not already placed there), and press the
„Start“ button. iColor measures the primary and
secondary colors plus a short gray balance and dis-
plays the results for both,
∆
E1976 (Lab) and
∆
E94.
Values lower than 5
∆
E are generally acceptable. You
can save the results in an extensive report as a PDF.
UDACT
The ugra Display Analysis and Certification Tool
(UDACT) allows - for the first time ever - the
individual and objective certification of
softproofing and color displays. Backed up by the
reputation of the Swiss Center of Competence for
Media and Printing Technology, the UDACT is the first
institutional approach for the certification of
soft proofing displays.
In today´s media landscape, an objective certifica-
tion of the calibration precision - like the ugra/fogra
MediaWedge for contract proofing - is one of the
most demanded developments. There is a lot of con-
fusion on the user´s side regarding the precision and
usage of softproof displays. This is also due to the
different color deviation methods and specifications
used in the validation routines of today´s
calibration software.
As a result, it is impossible to compare the validati-
on results of product A with product B. There are too
many unknown variables in use. Therefore, the user
has some fundamental questions:
The UDACT certification evaluates displays and includes
recommendations for the use.
If a display passed the tests, the “certified” or “passed” logo-
type will be displayed.
If a display fails in only one of the UDACT criteria, then the
whole certification fails.
The profile test offers an overview about the profile precision.
