modify PDF print colors

[MatjazBF]

I'm trying to remove grey areas from PDF that agents print.

I have modified the /opt/otrs/Kernel/Modules/AgentTicketPrint.pm but when an agent prints a ticket to PDF the PDFs aren't changed at all.
If i modify the CustomerTicketPrint.pm the PDFs that customers print are modified OK.

Am I missing something?

Thanks.

Is there a /opt/otrs/Custom/Kernel/Modules/AgentTicketPrint.pm? (Note the "Custom/" folder!)

UFF that was a good one!
The file /opt/otrs/Custom/Kernel/Modules/AgentTicketPrint.pm exists and if I modify it the PDFs are modified.

THANKS
