There are two related pieces of information needed for a print: The artwork (SVG and/or Raster) and the information for power, speed, focus, etc (the Metadata for the print). As I understand it (not having a GF yet) you select the art in the GFUI and then manually enter the metadata.
If you have a complex project with more than a few vector colors, that could get tiresome and error prone. Especially if you want to make changes to a few parameters to tweak the outcome or want to be able to replicate the print later.
Is there a way to, for example, have a spreadsheet where each row is the information for a vector color and the columns have the parameters for doing that part of the job?
One could also create scripts for the various image tools to create this metadata.
