Re: Photopolymer Photo Gravure Press Questions

[Jon Lybrook <jon@intaglioeditions.com>]

Hi Robert,

Yes, the angle of the curve of the upper roller directly affects the 
overall pressure.  You can get much higher pressure from an upper drum 
with a diameter of 10" than one of 4", and high, even pressure is what 
you want for printing photogravure quality from polymer plates.  I'm not 
a physicist, but I know I won't print photogravure on a press with a 
roller less than 10" if I can help it.

Size of the bed is in direct proportion to the size of the plate you 
want to print.  You should be able to print right to the edge, assuming 
your pressure is tight and even.

Best wishes,
Jon
