Reflectance Measures
Both traditional and ISO/IEC parameters are displayed in this area. For further
information on interpreting this data, see the “Traditional Print Quality Measures”
or “ISO/IEC Print Quality Measures” section.
Each display provides:
•
Visual reference for pass/fail levels (red and green bars within display
window)
•
Measured parameter level (blue indicator within display window)
•
Measured parameter numeric value
•
Alphabetic grade A-F or P(ass)/F(ail)
•
Visual Pass/Fail indicator (Alphabetic Grade displays green or red)
Traditional measures are displayed as the first three parameters:
•
R
l
= reflectance of light bar
•
R
d
= reflectance of dark bar
•
PCS = print contrast signal
ISO/IEC Parameters are displayed in the other five areas:
•
SC = symbol contrast
•
MOD = modulation
•
Rmin = minimum reflectance
•
ECmin = edge contrast
•
Defects = reflectance nonuniformities (for example, spots and voids)
ISO/IEC Scan Grade
The Quick Check
®
PC uses LED-style indicators to provide a quick, visual check
of displayed parameter grades, scan grade, and bar tolerance.
•
ISO/IEC Scan Grade
•
Scan Grade Indicator
•
Visual Pass/Fail red or green indicator (based on minimum grade).
•
“Low intensity” red and green indicates grades that are in the failing
and passing range respectively.
