Abrégé

A method is disclosed. The method comprises receiving a matrix representation of a source image to be printed, the matrix representation defining a colorant value for each of a plurality of print addressable locations, wherein the colorant values are representative of amounts of print colorant to be delivered to the print addressable locations during a printing operation. The method may comprise identifying, by processing circuitry, a region in the matrix representation having a first print addressable location and an adjacent second print addressable location, wherein a difference between colorant values of the first print addressable location and the second print addressable location meets or exceeds a defined colorant value threshold. The method may comprise determining, by processing circuitry, an amount of treatment fluid to be delivered to each of the plurality of print addressable locations during the printing operation, wherein an amount of treatment fluid to be delivered in the identified region is determined to be greater than an amount of treatment fluid to be delivered to adjacent print addressable locations having colorant values which differ by less than the defined colorant value threshold. An apparatus and a machine-readable medium are also disclosed.
