Functional Description
DOCUMENT CONTROL NOTE:
The controlled version of this document resides on MedNet. Any printed copy of this document is uncontrolled.
NOTE:
The emulsion side in general is slightly
smoother than the backing layer. This can be
heard by wiping over it
→
The backing layer
makes much more noise.
The backing layer has to be on top when the
film is laying in the tray.

Left / Right Shift Print Algorithm
At this position, where the TH has to print always Dmax, i.e. at the left and right image
border, the TH looses its characteristic relatively fast, which is determined by the Micro
profile calibration in production.
As a consequence, the TH produces after many prints small print stripes at this position
in 14" films, where the black border of the 10" films is located.
To prevent, that the TH has to print the black border always at the same position, a
left/right shift algorithm is built in.
For each film pack the complete image information is shifted slightly:
•
Pack 1 has 0 mm shift
•
Pack 2 has +0.3 mm shift
•
Pack 3 has 0 mm shift
•
Pack 4 has -0.3 mm shift
•
Pack 5 has 0 mm shift
•
And so on
The clear left and right borders are influenced by this shift mechanism but they are
within specification.
