Anyone have any good tips for flattening out ink swatch cards? Other than “stick them in a book and wait a few days”?
I had tried a stack of older ones smashed between some wood blocks and clamps which didn’t work. I don’t have a book press or anyplace to store one, but that also seemed like a promising option.
Most general methods for paper flattening involve moisture and heat, and I doubt the moisture part would play well with water-based inks.
