c:\jobs\samples\EM0_40.PLT and EM50_100.PLT
These are "EdgeMatch" charts that correlate to the EdgeMatch CMYK charts that are in the Fill Dialog box when you click on CMYK.
Each chart includes a base yellow percentage (ie 20% yellow). The Cyan and magenta change in 5% and 10% increments across and down. There is no black in any of the charts.
I usually scale the charts to 50% size so I can fit them 1 above the other. Also, the text is spot black, I would suggest you change that to be C or M to save a color.
There is also a Pantone_Color_Bridge.PLT file that is in the same folder.
I hope this helps. Thanks.
