Riot Design asked us to design and produce these business cards for them. Black Colorplan from GF Smith with black foil blocking to the face and white foil on the reverse. Originally we produced duplexed white and black Colorplan, which were really striking, but they curled a little due to the dye in the stock being dense in the black and none in the white which, when the heat of the foil block came into contact made the card react and warp a little.
