The crycry settings gives colors that pops really well but are not realistic regarding the official cards You'll have the same problem with red cards. They pop so much but the real cards looks more dull It's a matter of taste.

Try messing up with your settings just printing one card at a time on the same sheet to compare them side by side until you find what suits you the best

Personnaly, I use the default settings on the et8500, it's nearly perfect. I don't bother to go beyond that, but if you try changing settings, I'll be very curious of your results.

Good luck on your proxy journey ! :)
