Grayscaling and pixel shifting are the secret ingredients of sub-pixel imaging. They are sometimes used in 3D-printing to increase the resolution of the image and enable designers to create intricate structures with a high resolution and a smooth surface finish.

In this white paper, we explain how these two approaches work.

DLP 3D-printing aficionados can look forward to the part where we unveil the secret of 4K projectors and how 4K images are created from 2K DLP chipsets...
