I got my new Epson R2400 set up last night and tried to select watercolor as my paper type. It was gray along with several other paper types. I tried changing my matte black to photo black to see if that helped, as well as experimenting with the other variables. No luck. I'm printing through Photoshop and had a couple of other problems that I eventually figured out. Any suggestions on getting to the correct paper types? I haven't tried printing from the single sheet feeder but will try that next. Thanks.
