Hi,
I have designed a marketing folder and business card using Inkscape and am trying to get this printed at a professional printshop
I am just using red and black colours in my design and the printer says that they can reduce the price of the printing substantially if only red and black are used.

Sadly they (the printshop) informed me today that the PDF and the EPS files that I supplied them both contain all colours (i.e. there is blue values in the black part and yellow values in the red parts)
They require files that have these colours taken out in order to take advantage of the cost benifit of only using 2 colours.

How do I create the files that the printshop want in inkscape?

Here is the file in question in PDF and SVG. I wanted to also upload the EPS version (1Mb file) but seems the forum doesnt allow this.

If you didn't already know about, or use this, maybe it would help? It's an extension, announced and discussed in this topic: viewtopic.php?f=11&t=5943
