The matrices for clustered dot halftoning should not be too hard to generate. I think it boils down to which approach take to generate the thresholds matrix: https://dl.acm.org/doi/pdf/10.1145/127719.122727?casa_token=r7RLX2FwCCkAAAAA:accvlG1_tRYkdMpDpsxL3OoNkuFpNNNUxizbFE026c-utxJDibQxb-fnJ6Vann2UJfDVn61oKeN7eS4 https://dl.acm.org/doi/pdf/10.1145/127719.122727?casa_token=... > (ordered dither): This algorithm is generally identified as a dispersed-dot technique [Limb 69], but if the intensity threshold levels are spatially concentrated it results in a clustered-dot dithering.

Here's a tech report from HP that describes a stenography approach based on halftoning: https://www.hpl.hp.com/techreports/2010/HPL-2010-136.pdf https://www.hpl.hp.com/techreports/2010/HPL-2010-136.pdf
