Best paper to use, it will make you cry the moment you touch it -- SOMERSET. Printmaking paper, ANY serigraphy paper is beyond heaven. It hangs the moon in comparison to bristol board. Serigraph paper is MADE for ink (screenprinting ink ideally, yes, but I've experimented with a wide variety of other inks including standard commercial/industry and it's always stellar). It absolutely does a brilliant, velvety job with it. I think lithograph paper is also pretty nice but the issue is the cost. It's not cost-effective to buy packs Somerset for something like comic-making.
So, if money is of no concern, if you're looking for tight, velvety, rich ink lay, go for serigraph paper. It WILL NOT let you down. Otherwise, bristol board'll have to do. It comes at a great price, does a fairly good job with proper inks (cheap/entry-level media doesn't work very well on it), and comes pre-cut at standard sizes.
