Up until the mid-1960s, wood ad mats were molds used to create lead castings for letterpress printing. The casting was created by pouring hot lead onto the wood mat. After the lead cast cooled, it was secured to the press, where ink and then paper were placed on top. Finally, pressure was brought down on the casting to create the print on the paper. The wood ad mat molds were usually thrown away once the lead cast was made.
