Polarized M3 measurements are perfectly smooth in the shadows You can see that the bottom half of the M2 red gamut “rock” is quite bumpy whereas the polarized M3 blue gamut rock is perfectly smooth. i1Pro2/iSis M2 measurements are shown in red while the i1Pro3plus M3 measurements are show in blue. Let’s look at and compare M2 and M3 measurements of the same Breathing Color Crystaline Glossy canvas. These are the reflections that polarization eliminates. A close up of a profiling target on glossy canvas. The sole purpose of polarization is to eliminate the reflections on textured glossy surfaces that can lead to poor measurements in other conditions. The M3 measurement condition is a polarized version of M2 excluding UV data and media fluorescence. A longer 23 inch handheld scanning ruler supports large format page sizes and an updated iO3 Table supports the i1Pro3plus for reflective measurement. Transmissive scanning allows us to measure and profile backlit printing processes with any light table. Polarized M3 measurements mean smoother shadow tonality and improved deep color saturation on textured surfaces like glossy canvas. The large 8mm aperture (vs the i1Pro2’s 3.5mm) translates into rich, extreme shadow measurements and averaging of uneven surfaces and large dot patterns. The i1Pro3plus spectrophotometer contains a new LED illuminant that allows for simultaneous M0, M1, M2 measurement in a single pass. XRite brings back polarized, transmissive and large aperture measurements with the i1Pro3plus spectrophotometer.
