a. Different types of color film will reproduce differently
on
Cibachrome materials; i.e., will require different filter packs.
b. Transparencies of inherent low
contrast
will
reproduce
more
faithfully than those of high contrast.
c. Enlargements of great magnification will appear to be visually lower
in contrast than small enlargements.
d. Due to the direct positive characteristics of Cibachrome materials,
small scratches and dirt on the transparency will be more apparent in the
final product than with negative/positive photographic printing materials
because they show as black defects which are more difficult to retouch.
e. It may not be possible to fully correct in printing transparencies
that have an overall tint or color cast due to improper film exposure and/or
processing.
f. Particular care should be exercised in the printing of high key
transparencies.
Be sure that there is sufficient density in the main
subject to reproduce on Cibachrome materials.
g. Understand that you may never totally match all areas of the print
or transparency to the original unless you are willing to use supplementary
printing techniques such as dodging, burning-in, and/or area color
correction (retouching).

Color Correction Filtration.
No special filters are required for Cibachrome materials.
The usual
photographic printing filters, as well as color enlargers, can be used. In
addition to the color filters, an ultraviolet-absorbing filter must always
be inserted in the light path.
On the label of each pack or roll of Cibachrome material is a standard
filtration for that particular emulsion.
It refers to Kodak CC filters.
These filter values were established under certain standard conditions; they
cannot necessarily be used as absolute values for a given situation.
However, they are a useful guide when changing from one emulsion number to
another.
The new filtration can be found more easily, thus reducing the
amount of time and material wasted.
Color correction techniques using CC or CP or dichroic filters and
Cibachrome materials are the same as when using other reversal color papers.
