Evaluation
Evaluate the test image at the 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 dots.
(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.)
NOTE:
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.
