d-lab.2, d-lab.2plus, netlab.2plus: Operation
4.5.1
General Information Regarding the Production Balance
We recommend to make changes in the production balance only if it is clear, after a
longer observation period and sufficient production experience, that the complete
production must be corrected in one direction.
We recommend to have parameters modified only by experienced operators.
Modifications are only effective after a new start.
These settings are not considered in the back print as the production balance defines the
basic balance (0-value).
Correction values entered later (e.g. via correction configurations or for image
improvement) are added to this 0-value (up to ±9 maximum) and can be included in the
backprint (if selected there) – see
chapter).
In case of color and density corrections the influence depends on the entered correction
Setting the Correction Impact (for color negative and digital)
impact (see
chapter).
We recommend,
to leave the parameters Area contrast, Detail contrast, Saturation, and Sharpness
–
in the production balance always on 0,
– Applies only to d-lab.2/2plus
the parameters of the Color and Selector logic both on 1.0,
and to define the required corrections only via the correction configurations. The values
adjusted via correction configurations can be selected for the back print and thus are
easier to follow up.
Special features for file prints/digital
In contrast to negatives the image files have an absolute color allocation:
0/0/0
= black
100/100/100 = gray
255/255/255 = white
255/0/0
= pure red, etc.
The machine is adjusted in such a way (default setting) that e.g. three equal numbers on
the print actually result in gray.
Corrections can be made by correction configurations.
Furthermore in file print a pure brightness increase (density, via corrections or the dTFS
function), for example, has the effect that shadows become lighter whereas the light areas
come out only slightly lighter or almost unchanged which in turn means a contrast
reduction.
