Hi there

Does anyone know if it is possible to tonally adjust images within a 'final' PDF file on a global scale?
Im thinking maybe the applying of a Photoshop curve for instance...?
I have looked through Pitstop but can not see anyway there of doing it, editing each image into Photoshop is not a option - unless there is a possibility of batching that?
Any plug-ins available to do such things etc etc?

Any advice or suggestions welcomed

Thanks
Noel

Noel,

have a look at callas pdfToolbox 4. You can ether do a global correction by entering a dotgain compensation value. Alternatively you can write your own gradation correction curve and apply it.
