Nowhere, nowhere, nowhere have I found documentation on a reliable method for determining the best ink restrictions for optimum color gamut.
Yes, RIP manufacturers often include their own set of concocted testcharts and tools with suggested methods for setting restrictions and limits.
But, in the end, these methods never seem to help one arrive at a definitive, no-reservations solution.
SWOP standards aren’t really applicable, here.
Total ink limit specs by a media manufacturer is really relative - relative to whatever solid ink density target settings they used (whatever they are…).
Can’t locate HexaChrome density standards in the event that would give me additional clues.
Add to the mix a hand-selected array of 12 individual ink colors from three or four different mainstream ink providers, and I’m practically hanging my butt out in the wind.
I recently tried setting my individual densities according to where the LCh Chroma values peaked, but that didn’t seem to do the trick. Too much Yellow and not enough Cyan and heavy bleeding on violet-blue testchart swatches. (GCR3 - 300% total ink)
Trail and error - educated hit or miss…? There has GOT to be a better way.
What boat am I missing here? Or, am I on the same ferry ride as everyone else?
