The printing apparatus includes a transport system arranged to move the media through the printing apparatus in a process direction. The lamp array includes at least one lamp having a longitudinal axis arranged in a direction parallel to the process direction and adjacent to the transport system. ## Claims ### Claim 1 A lamp array for drying a liquid ink on a media in a printing apparatus, the printing apparatus comprising a transport system arranged to move the media through the printing apparatus in a process direction, the lamp array comprising: a plurality of lamps, each lamp of the plurality of lamps having a longitudinal axis arranged in a direction parallel to the process direction and adjacent to the transport system; and, a perforated plate comprising a plurality of through holes and arranged between the plurality of lamps and a cooling plenum, wherein the plurality of lamps are equidistantly positioned substantially across a cross process distance of the transport system, and wherein the cooling plenum forms a drying region below the plurality of lamps and air passing from the cooling plenum through the perforated plate is distributed about the drying region. ### Claim 2 (depends on 1) The lamp array of claim 1 wherein each lamp of the plurality of lamps is equally spaced relative to each adjacent lamp. ### Claim 3 A drying system for drying a liquid ink on a media in a printing apparatus, the printing apparatus comprising a transport system arranged to move the media through the printing apparatus in a process direction, the drying system comprising: a plurality of lamps, each lamp of the plurality of lamps having a longitudinal axis arranged in a direction parallel to the process direction and adjacent to the transport system; a cooling plenum arranged elevationally above and adjacent to the plurality of lamps; an exhaust skirt arranged adjacent to the cooling plenum; and, a perforated plate comprising a plurality of through holes and arranged between the plurality of lamps and the cooling plenum, wherein the plurality of lamps are equidistantly positioned substantially across a cross process distance of the transport system, and wherein the cooling plenum forms a drying region below the plurality of lamps and air passing from the cooling plenum through the perforated plate is distributed about the drying region. ### Claim 4 (depends on 3) The drying system of claim 3 wherein each lamp of the plurality of lamps is equally spaced relative to each adjacent lamp. ### Claim 5 (depends on 3) The drying system of claim 3 wherein each lamp of the plurality of lamps is independently controlled. ### Claim 6 (depends on 3) The drying system of claim 3 wherein at least one lamp of the plurality of lamps is energized with a unique duty cycle. ### Claim 7 (depends on 3) The drying system of claim 3 further comprising: a duct in fluid communication with the exhaust skirt; and, an air exhaust in fluid communication with the duct, wherein the cooling plenum forms a drying region below the plurality of lamps, air passes from the drying region through the exhaust skirt to the duct and from the duct to the air exhaust. ### Claim 8 (depends on 3) The drying system of claim 3 wherein the cooling plenum forms a drying region below the plurality of lamps and the exhaust skirt is arranged outside of the drying region. ### Claim 9 A lamp array for drying a liquid ink on a web in a printing apparatus, the web moving through the printing apparatus in a process direction, the lamp array comprising: a plurality of lamps, each lamp of the plurality of lamps having a longitudinal axis arranged in a direction parallel to the process direction and in a region within the printing apparatus adjacent to the web; and, a perforated plate comprising a plurality of through holes and arranged between the plurality of lamps and a cooling plenum, wherein the plurality of lamps are equidistantly positioned substantially across a cross process distance of the region, and wherein the cooling plenum forms a drying region below the plurality of lamps and air passing from the cooling plenum through the perforated plate is distributed about the drying region. ### Claim 10 (depends on 9) The lamp array of claim 9 wherein each lamp of the plurality of lamps is equally spaced relative to each adjacent lamp.
