      Harold is referring to the software used for trapping spot colors, ie, creating a trap or spread in the plate/film around areas which abut or overlap. I generally do it manually for single panel work, but in large complex jobs, that can be daunting if not impossible.

      There are a few proprietary packages which incorporate the trapping algorithms, but as Harold notes, the processes are protected by patent, generally, and until somebody can engineer it in a way which does not infringe, there will be no way to write an open source version.

      Does one need to identify spot colors to create binary plates?

Boxcar had started to build its own print output software based on Ghostscript last year (results of which are on our website as the platemaking plate preview) but was unable to make a standalone RIP because there was no FOSS trapping library for spot colors...that I could find anyway.
