There are a few different types of paint that can be used for block printing. One type is water-based paint, which is best for beginners because it is easy to clean up and doesn't require any special equipment. Another type is oil-based paint, which creates a more durable print but can be difficult to work with. Whichever type of paint you choose, make sure it is thinly applied so that it doesn't clog the pores of the block.
