Adjust input data smoothing and various perceptual and colorimetric settings.

1. Click the Processing tab.
2. Set the values for the following:
   • Input data smoothing: Controls the amount of smoothing that is performed on the measurement data used to build the front side model of the printer. Increase this control to smooth out noisy printers. Decrease this control for less noisy printers.
   • Table smoothing: Controls the amount of smoothing to the output tables. There are separate controls for the B2A0 and B2A1 transforms. Increase the smoothing for rendering smoother gradients and decrease the smoothing for more accurate color renditions.
   • Table sizes: Determine the number of table entries in the input and output color tables. In general, larger tables produce more accurate colorimetric predictions, take longer to calculate, and result in ICC profiles that take up more disk space. For critical print-reproduction tasks, increase the output table sizes. For critical proofing tasks, increase the input table sizes. The defaults are intended to produce good multi-purpose ICC profiles.
   • Extended gamut inks: Control how the extra-gamut colorants are mixed with the C, M, and Y primaries. Guidelines for selecting three-color overprints versus two-color overprints depend on the colorimeric strength of the extended gamut colorants. If the colorants are light and used to primarily extend the color gamut at the top of the gamut, select the use of the three-color overprint. If the colorants are darker and high density, then consider not selecting the option for that colorant.
     Note: The choices displayed depend on the capabilities of the printer you are profiling.
     Possible choices are:

     • Use Orange (or red) in three-color overprint to extend gamut: Select this option to allow full three-color overprints (O+M+Y) of O, M, and Y inks. If unselected, orange overprints are limited to O+M and O+Y.
     • Use Green in three-color overprint to extend gamut: Select this option to allow full three-color overprints (G+C+Y) of G, C, and Y inks. If unselected, green overprints are limited to G+C and G+Y.
     • Use Violet (or blue) in three-color overprint to extend gamut: Select this option to allow full three-color overprints (V+M+C) of C, M, and V inks. If unselected, violet overprints are limited to V+M and V+C.
