The boards are 5/8" and are grain printed. I take your point about using a
non aqueous glue. I thought about using a spline but the grain print surface
might be too delicate to go though my router. Some experiments are in order
before I start construction.

I want to butt joint two grain printed boards, one 11.5" wide, one 8" wide
and both 6' long. I'm thinking of using biscuits and water borne glue.


You don't say how thick, but given the way MDF or other fine-grain
particle boards swell and stay, I'd go dry biscuits for alignment, and
something other than a water-based glue or sparingly.

Better would be the reverse glue joint type of router bits, though if the
pattern is plastic imprint, you might want to check it on a scrap piece.
Continuous spline is easily enough done, and you could make it a bit
deeper than normal if the joint will be under any kind of stress.
