The choice of an ink for an alternative photo process can be quite different to the choice of ink for blocking masks like used in PCB processes or line and halftone printing in silkscreen. For example the optional HP Z3200 media preset for alternative photo process films uses the green ink mainly as it modulates the opacity for UV better than the more opaque black ink would do. -- Met vriendelijke groet, Ernst http://www.pigment-print.com/spectralplots/spectrumviz_1.htm January 2014, 600+ inkjet media white spectral plots.
