A print system (50, 50a) comprising: a dryer (120, 120a) to dry a sheet of paper; a media feeder (115, 115a) to feed the sheet of paper into the dryer (120, 120a); a controller (105, 105a) to vary a speed of the media feeder (115, 115a); a communication interface to receive data associated with an image to print on the sheet of paper; and a processor (100, 100a) coupled to the controller (105, 105a) and the communication interface, wherein: the processor (100, 100a) is to determine a first density index for a first portion of the image and to determine a second density index for a second portion of the image; wherein the first portion is a leading edge and the second portion is a trailing edge, and the leading edge is to enter the dryer (120, 120a) prior to the trailing edge, the first and second density indices are based on a density of ink printed to first and second portions respectively and at least one of the first and second density indices is determined using a correction factor to account for the different amounts of time spent in the dryer by the leading edge and the trailing edge; and the processor (100, 100a) is to adjust the speed of the media feeder (115, 115a) via the controller (105, 105a) based on the first density index and the second density index. a dryer (120, 120a) to dry a sheet of paper; a media feeder (115, 115a) to feed the sheet of paper into the dryer (120, 120a); a controller (105, 105a) to vary a speed of the media feeder (115, 115a); a communication interface to receive data associated with an image to print on the sheet of paper; and a processor (100, 100a) coupled to the controller (105, 105a) and the communication interface, wherein: the processor (100, 100a) is to determine a first density index for a first portion of the image and to determine a second density index for a second portion of the image; wherein the first portion is a leading edge and the second portion is a trailing edge, and the leading edge is to enter the dryer (120, 120a) prior to the trailing edge, the first and second density indices are based on a density of ink printed to first and second portions respectively and at least one of the first and second density indices is determined using a correction factor to account for the different amounts of time spent in the dryer by the leading edge and the trailing edge; and the processor (100, 100a) is to adjust the speed of the media feeder (115, 115a) via the controller (105, 105a) based on the first density index and the second density index. the processor (100, 100a) is to determine a first density index for a first portion of the image and to determine a second density index for a second portion of the image; wherein the first portion is a leading edge and the second portion is a trailing edge, and the leading edge is to enter the dryer (120, 120a) prior to the trailing edge, the first and second density indices are based on a density of ink printed to first and second portions respectively and at least one of the first and second density indices is determined using a correction factor to account for the different amounts of time spent in the dryer by the leading edge and the trailing edge; and the processor (100, 100a) is to adjust the speed of the media feeder (115, 115a) via the controller (105, 105a) based on the first density index and the second density index.
