Claim Text:
1. A printer comprising: a colorant application device to apply colorant to a substrate at each of different image regions; a treatment fluid application device to apply treatment fluid to the substrate at each of the different image regions; and a circuit to process incoming digital image data for printing an image on the substrate, to determine an amount of the colorant to apply to each of the different image regions within the image via the colorant application device based on the digital image data, to determine colorant colors in the image regions, and to selectively set an amount of the treatment fluid for each of the different image regions at least partially based on a sequence of application of the colorant colors, and to instruct the treatment fluid application device to apply the set amount of the treatment fluid to the substrate, wherein the colorant application device and the treatment fluid application device are part of a scanning carriage, wherein the treatment fluid application device and the colorant application device are arranged to apply the treatment fluid and colorant, respectively, during a same print pass, and wherein the circuit is further to determine a pass speed over the different image regions, and to selectively set the amount of the treatment fluid for the respective image region at least partially based on the pass speed.
