Quad file syntax and conventions

Quad file syntax and conventions

2018-03-11 by dtrout@...

This is probably a question for Roy: What are the syntax rules for Quad files?

I understand that the first line (e.g. "## QuadtoneRIP K,C,M,Y,LC,LM,LK,LLK,OR,GR") is a header that lays out the ink channels in the printer, and that each block of 256 "pixel value" bins holding the 16-bit ink density values is preceded by its own header (e.g. "# K Curve").

I'd like to embed some comments in some of my Quad files to help keep track of things like remapping status and documentation on which monochrome inks are actually in each printer ink channel.

Is it OK to insert comment lines (starting with a "#") in the file after the top header and before the ink density blocks? A quick test seems to confirm this will not cause problems but I'd like to be sure this will not break anything (now or perhaps in the future).

Can comments be inserted elsewhere in the file, e.g. before a specific ink channel block of density values?

Thanks,
Dave

Yep. It’s ok.

Best,
