Recently, new approaches have been presented to tackle these issues, and aim at closing the gap between the intended appearance and the printed result. These approaches solve different aspects of the problem: high color reproduction fidelity [Babaei et al. 2017; Brunton et al. 2015; Shi et al. 2018] , alpha channel translucency printing [Brunton et al. 2018; Urban et al. 2019] , or compensating for lateral scattering to increase texture sharpness [Elek et al. 2017; Sumin et al. 2019 ].
