d-lab.2, d-lab.2plus, netlab.2plus: Operation
4.4.8.4 The dTFS function (digital Total Film Scanning: Image enhancement in digital print files)
dTFS determines color and density corrections for digital images, to correct possible color
casts. The aim is to compensate for the characteristics of different digital cameras.
The dTFS function only influences images of digital cameras without editing. Images
which have been edited and/or generated or saved in an image processing program, will
be printed without dTFS, even when dTFS is switched on. The system detects
automatically if an image comes from a digital camera and is still untouched, or if the
image has been edited.
The minilab does not differentiate during detection where a digital image file comes from.
Which means, independent whether the digital image file comes from network or from a
medium inserted in a drive of the minilab, the same image detection processes are used.
Images are selected as being edited or generated by an image processing program if the
image contents meet the following criteria:
Images with one-colored border, or with graded border in one color under the
–
following restrictions:
Borders with ornaments will not be selected.
–
If the images in a laboratory are sent from an image box/Workstation with SW
–
Version 5 and up to the d-workflow (network server accessed by the minilab), white
borders will be sent as a separate PfDF parameter, and only the minilab will
combine image and border. In this case the image files are not selected.
Colored borders are included in the image calculation at the workstation. Therefore
images with colored border will be selected.
If borders are assigned to images via the kiosk-Software on a workstation, these
–
borders are included in the image information independent of their colors and the
images will be selected.
Index prints
–
Sepia prints
–
Black-and-white prints
–
Synthetic images, such as computer graphics or images edited with graphic programs,
–
if they correspond to the extensive internal search criteria.
Images with three- monochromatic corners (not graduated). This guarantees that oval
–
frames, for example, will be selected.
Images edited or created with an image processing program are detected with a reliability
of 80%.
If such images are not detected by the selection criteria, they will be printed with dTFS
(always provided the presetting is "On").
It cannot be excluded that the image information in unedited images of digital cameras
corresponds to the selection criteria. These images will then be printed without dTFS.
However, chances that this occurs are only approx. 1%.
