I am preparing artwork to be sent to a printer for the production of custom umbrellas. We want to print a logo on black fabric with 2-inks: white-spot and orange-spot (PMS 021) colours. The path in the picture is the stroke for the type. That's the one I want to be black, the fabric. Shown below is only one character coloured in orange.
How do I get a stroke on an object to knockout underlying white ink and to not print on the stroke at all so that it ends up looking like the second image below? With 0% C 0% M 0% Y 0% K process swatch?
And how can I preview it? We don't have black paper nor white ink.
