Sometimes the size of the document is correct but the
output orientation is set incorrectly.
You should also check the printerdriver (PPD) used to
print the document. Make sure it is an up-to-date and
correct PPD for the device you are printing to.
I have also encountered instances where customers defined
an incorrect film width in the setup menus of their
imagesetter. They ordered a new, larger film size but forgot
to update the setup of the imagesetter.
RIP software causes error
Some versions of Agfa RIP software include an option to
let the RIP add cropmarks and registration marks. The RIP
software does this by adding an pageborder. Sometimes this
border makes the page size exceed the imageable area of the
imagesetter. |
