A colour file as both PNG and PDF (your artwork, with registration marks on a gang sheet), a build file also as both PNG and PDF (the height map, in true single-channel grayscale so a RIP reads it as one ink), and a cut file — all in one zip, all describing the same frame at the same DPI so they stack correctly in RasterLink. The PDF is included because that is what most RasterLink users actually place; the PNG is there as well if you prefer it.
