Machine specific tools, software tools and auxiliary means
lightbox as follows:
(1) Fields 1 (4x) consist of 6 squares
with horizontal and vertical black
and white stripes (1, 2 and 3
pixels wide).
Check: Each of the 6 squares
must show constant distance
between the black and white lines
(no interferences may be visible,
leading to unequal distances).
(2) Fields 2 (4x) have the same
pattern as fields 1, but less
contrast
Check: All 6 squares must be visible.
(3) Fields 3 (3x) consist of several squares with the same density.
Check: The individual squares must show constant density. No stripes or
other artifacts.
(4) Field 4 consists of a black square (100% black) with a smaller grey
square inside (95% black)
The square must show 2 different densities, i.e. inside there must be a
smaller square with slightly lower density.
(5) Field 5 consists of a white square (0% black) with a smaller grey square
inside (5% black)
Check: The square must show 2 different densities, i.e. inside there must
be a smaller square with slightly higher density.
(6) Field 6 consists of a black square (100% black).
Check: The square must show Dmax (default: 3.2 O.D.)
(7) Fields 7 consists of a white square (0% black).
Check: The square must show fog level (for clear based film approx. 0.1
O.D., for blue based film approx. 0.2 O.D.)
To check density reproduction, especially for Dmax, use the LinCheck.ZIP
test image and measure in the "Density measurement area", as there also
the CDM is measuring. Only in this case the measured densities are
comparable.
