The experiment studied effects of paper on the height and glossiness of UV ink-jet 3D printing. The results showed that there all existed penetrations between the 1st ink layer and three kinds of paper, the bigger the roughness and bulk of paper were, the larger the penetration was, and penetration between the 1st ink and paper was obviously larger than that between two ink layers. Penetration between two ink layers was stable, almost not affected by paper. The bigger the roughness and bulk of paper were, the smaller the glossiness of ink layer was. There appeared directional ink strips on ink layer on three kinds of paper, beginning from the 3rd ink layer, there also appeared ink pits on ink layer on paper whose roughness and bulk were the biggest, which showed printer precision was also an important factor for the glossiness, apart from paper. Thus, the tight and smooth paper should be selected in UV ink-jet 3D printing. Before printing, pretreatment should be done to exclude the influence of the 1st ink layer and the ink strips.

Scan-digitizing is one of the main ways to digitize the original. Building scanner profiles are usual practice to get the consistent color. In the paper, we describe how to get the best possible ‘Raw RGB’ image from a scanner. First we measured the accuracy of those different input profiles. The profile accuracy depends on the relationship between scanner RGB and the corresponding LAB or XYZ values. Then we compared the range of those input profile tones. The ideal tone response curve can be decided by setting the scanner gamma. So a good input profile can faithfully render the dark and murky appearance of an underexposed image or the washed-out appearance of an overexposed one. In order to get a good scanner profile we proposed a method to determine a suitable tone response curve. A new algorithm was then developed according to N-component LUT-based input profile. Experiments were carried out to compare these scanner profiles. The results showed that the ICC profile generated by the new algorithm has obvious advantages in accuracy and grey predicting.
