Apparatus are provided, including a macrouniformity compensation mechanism to modify data exchanges between device-independent image data and a one-dimensional imaging device, to compensate for a lack of macrouniformity caused by the one-dimensional imaging device. The macrouniformity compensation mechanism includes an input-output value converter to convert an input intensity value for a given pixel to a corresponding output intensity value. The output intensity value is determined as a function of the position of the given pixel in the cross-process direction of the image and the level of the input intensity value. The input-output value converter includes a number of stored conversion parameter sets corresponding to respective different positions in the cross-process direction of the pixel data. The number of stored conversion parameter sets is a fraction of the total number of pixel positions in the cross-process direction of the pixel data.
