Flexography Printing and the The Letterpress process are considered to be comparable.  However the difference is that in Flexography Printing the material used to make impressions are flexible like rubber to accommodate most uneven surfaces.  Much like Letterpress Printing the ink is placed on the plate which then touches the paper and an impression is then made.

Flexography Printing is a water based printing process which is widely used in the packaging industry to create such products such as cardboard boxes, plastic bags and cartons etc.
