Chapter 4 Basic Operation
7. Effective Exposure Area
When loading the plate onto the drum of the PT-R, clamps are used to secure the
leading and trailing edges. For this reason, the parts of the plate that are hidden by or
in the shadow of the clamps cannot be exposed by the laser. The effective exposure
area of the PT-R is thus the area of the plate excluding approximately 15 mm at the
leading edge and 12 mm at the trailing edge, as shown below.
CAUTION
!
If the leading and trailing grip margins are set to less than 15 mm, or if the
image is output using the type B operation method, the output image will
exceed the above effective exposure area. In this case, the image data
outside the effective exposure area is cut off.
