33-18 ColorWise Pro Tools4. Edit and save the simulation as described in steps 5 through 10 of the procedurestarting on page 3-14.For this new simulation to be automatically applied to a print job, the CMYKSimulation, Simulation Method, and Output Profile settings must be the same as thoseused when you edited the profile. If the Simulation Method is different or a differentoutput profile is selected, the Master simulation is applied.N OTE : A Simulation Profile can have a custom Master and one or more custom links—up to three links (Quick mode and the two Full modes) for each output profile on thesystem. (For the CMYK Simulation Profile option in the printer driver, note that ifyou select a custom profile for which the output ink percentage is greater than 0 andthe input ink percentage is 0, the Use Master print option will have no effect.)Undoing simulation editsYou can undo the changes you made to simulations (master and linked) in thefollowing ways:• If you have not yet saved your edits, click Done on the Color Editor menu bar, anddo not save the changes.• If you saved your edits under a new simulation name and want to delete all edits (inMaster, Quick, and Full modes) to the simulation, see page 3-7.Correcting gray balanceThe AutoGray feature lets you use the copier’s built-in scanner as a measurementdevice for correcting the gray balance of output profiles. Gray balance refers to thequality of neutral gray tones in a profile. In many cases, gray tones may contain abluish or reddish color cast. AutoGray helps shift these tones back towardneutral grays.EX12
