Appearance reproduction is an important aspect of 3D printing. Current color reproduction
systems use halftoning methods that create colors through a spatial combination of different …

Color texture reproduction in 3D printing commonly ignores volumetric light transport (cross-
talk) between surface points on a 3D print. Such light diffusion leads to significant blur of …

We propose a workflow for spectral reproduction of paintings, which captures a painting's
spectral color, invariant to illumination, and reproduces it using multi-material 3D printing …

3D printing technology is a powerful tool for manufacturing complex shapes with high-quality
textures. Gloss, next to color and shape, is one of the most salient visual aspects of an …

Baryshnikov presented a remarkable algebraic topology proof of Arrow's impossibility
theorem trying to understand the underlying reason behind the numerous proofs of this …

Laser irradiation induces colors on some industrially important materials, such as stainless
steel and titanium. It is however challenging to find marking configurations that create …

Color distortion often occurs during transmission and reproduction processes, and existing
spectral prediction methods have the disadvantage of low prediction accuracy in halftone …

Inkjet 3D printers produce solid shapes using very small voxels made of polymeric materials.
While state-of-the-art methods for predicting the appearance of inkjet-printed objects …

We introduce a novel ink selection method for spectral printing. The ink selection algorithm
takes a spectral image and a set of inks as input, and selects a subset of those inks that …

Multi‐channel printing employs additional inks to improve the perceived image quality by
reducing the graininess and augmenting the printer gamut. It also requires a color …
