The Austrian Post has for the last few years contracted
out to foreign printers much of the Austrian stamps production
which was previously assigned to the Austrian State Printer.
Here below are some from the series of Austrian automobiles
and motorcycles issued in the last few years.
Three were printed by the OeSD (State Printer) and one by
the Hungarian Printer, ANY Security Printing Company PLC.
Can you tell the difference and why?
All were printed using the offset/litho method but one
has what appears to be stochastic screening compared to
the more regular uniform rosette type of screening.
