A paper sample press has a drawer slidably mounted on a base. A plurality of generally vertical guide posts are mounted on the base on opposed sides of the drawer. The drawer has a lower platten mounted thereon for supporting a stack of paper samples. The drawer is slidable on the base from a retracted position between the guide posts to an extended position wherein the lower platten is extended out from between the guide posts, and returnably slidable on the base from the extended position to the retracted position. A vertically selectively actuable press cover is vertically mounted on a piston above the lower platten when the drawer is in the retracted position. The piston is selectively actuable so as to selectively lower and elevate the press cover between a raised position and a lowered paper sample engaging position. The paper sample press has piston support and selective actuation means for supporting and selectively actuating the piston vertically over the lower platten so as to vertically selectively translate the press cover along a vertical press axis aligned with the lower platten between the raised position and the lowered paper sample engaging position. The piston support and selective actuation means is mounted on the guide posts. Constant compression means is provided for applying a generally constant compression pressure along the vertical press axis to a stack of paper samples placed on the lower platten when the drawer is in the retracted position and the press cover is in the lowered paper sample engaging position.
