Hi Chris,

Eric is on vacation.  The only way  I can think of doing what you want is to create an OFM file from the TV current TV color table with OFMSAVE and then use that as the OFMFILE in KNTR. 

Another factor in getting exactly what you see on the TV into a hard copy is the RGBGAMMA in LWPLA.  The XAS default (i.e., what is used by the TV) is RGBGAMMA=2.2.  Most people leave this as 0, which is why even when using the "rainbow" OFMFILE (which is equivalent to TVPS), they don't get the same color scheme they see on the TV. 

If you want to do everything on the TV you can also use TVWEDGE and TVWLABEL and take a snapshot, but the KNTR route looks better.
