Customizing
a state-of-the-art electronic printing process
Combi-DX1 charts are the result of extensive
research to
develop the ultimate test materials. Combi DX1 benefits include:
-
Improved color stability
- Spectrophotometrically neutral grayscales
-
Selected color pigments with spectral
characteristics that complement real life
colors, and modern camera colorimetry
- Greater flexibility enabling more different
patterns
- DX-1 patterns match CamAlign front-lit chart

Combis are easy to use . . .
. . . because they are
precision "Optical Signal Generators" (OSGs) that
produce waveform and vectorscope displays designed
to mimic standard electronic test signals.
Featuring a "Combi"nation of
test elements, Combis save time and are easier on
the budget.
Combi-DX1 takes
the guesswork out of matching video cameras!
Align multiple cameras using
Combi-1's color patches and you will be delighted
how simple image matching can be. Combi-1 is
especially helpful when aligning to different types
of lighting, quartz, HMI, fluorescent etc. Our
aim is to give you consistent, virtually identical
outputs - every time! Combi deviation
from aim values are specified in CIE units.
Maximum tolerance for any color is 5 CIE L*U*V
units, with an RMS maximum of 2 units. As a
yardstick, cameras considered "well matched" by eye,
typically have a CIE color difference of 10 units.
Choose the Combi-1
that's Best for You!
To avoid moiré
and other problems caused when typical printed
patterns "beat" with a camera's CCDs, all Combi-1
and Combi-2 OSGs are produced on continuous tone or
dye image films. Mounted in shatter-proof,
clearer than glass plastic, OSGs are packaged with
individual calibration sheets in sturdy protective
cases.
Uncertain which camera to buy?
Combi-DX1 can be invaluable in helping you make the
best purchase decision, with confidence.
Use with other
Illuminators
While Combis are designed
to be used with the
Ambi illuminator
we can supply CombiMattes to use Combi OSGs with
other manufacturers' light boxes or spherical
illuminators.
