I am trying to place a psd with 2 spot channels into illustrator. The problem is that my printer doesnt want the channels named as Pantone, he just wants them renamed as brown and black. When I try to place them into Illustrator I get these errors and it will not place the file?
CMYK Files already have a black, so you can copy and move the pixels from the spot channel to your black process channel, then delete the black spot channel. Unless you are doing a double hit of black and want to use the process black with an extra plate of spot black. As Ton mentioned you cannot use the "Black" for a spot channel as that is reserved for the process color. Photoshop should really fix to not allow that name.
