Waterbased ink on Cardboard

Waterbased paper printing inks are fine for cardboard. They air dry, and with paper there isn't really a difference between drying and curing since it doesn't get washed.

Fabric printing ink will work too. I've done a few test prints that way for record keeping without problems.

Matsui's RC inks says it is good for applications on fabric and well as paper products. Paper doesn't get washed, but my concern wash when it gets wet during shipping, if the waterbased ink will run or smudge.

Fair point. Can't say I've tested it in that application. My gut instinct is that it would be no better or worse than most methods you could use. If it got really wet I'd expect some smudging, but not serious run off. But obviously you'll want someone with some experience on this specifically or your own testing rather than a gut instinct
