We are in the process of refining our ability to profile our large format digital printers in house using the latest version of i1 profiler with a i1 (UV filter attached) to help correct for our optically brightened substrates.
We believe the most recent profile we have build is very linear and produces pleasing color (perceptual intent) for photographic work. However a lot of what do print requires the best possible match to PMS spot colors. We have found that if we use the color replace function in our RIP that we are able to achieve color matches that our profile says are out of gamut.
My questions is if we are able to produce a color mix using the same inks on the same printer & substrate that produce a good spot color match via the same printer CMYK print how can these colors be considered out of the icc v2 profile gamut we built with i1 profiler:?: Should we be looking at using a different rendering intent, a different way of building blacks. Have we done something that has limited the gamut of our profile or is it that yes we can achieve these color but they are out of gamut because their inclusion would cause spikes the profile that are corrected for in the processes as they would not be linear:?:
