One issue, in particular, with CVDg...

We present an interactive CG (Computer Graphics) design system based on virtual woodblock printing, with the stress on an aspect of a tool to enjoy creation in a virtual space. This system is a simulation of real woodblock printing: generating a woodblock, spreading inks on the woodblock, putting a paper sheet on the woodblock, and rubbing the paper sheet with a Japanese squeegee “BAREN” in a v...

In this study, two capillary electrophoresis modes, capillary zone electrophoresis (CZE) and micellar electrokinetic chromatography (MEKC), were employed for the examination of gel ink fingerprints. The optimized CZE conditions were as follows: running buffer, 0.2M boric acid and 0.05M sodium tetraborate; pH, 6.47; detection, 214 nm; separation voltage, 20 kV MEKC conditions were as follows: 20...

UV printing is different from conventional printing in many ways. It is still ink on paper but the ink dries through a completely different process. Instead of having solvents in the ink that evaporate into the air and absorb into the paper, UV inks dry through a photomechanical process. When the inks are exposed to ultraviolet lights they turn from a liquid, or paste, to a solid. There is sign...

Nanoscale patterns with high conductivity based on silver nanoparticle inks were fabricated using spray coating method. Through optimizing the solution content and spray operation, accurate nanoscale patterns consisting of silver nanoparticles with a square resistance lower than 1 Ω /cm2 were obtained. By incorporating in situ sintering to substitute the general post sintering process, the time...

A blue tattoo is more resistant to laser therapy than black or brown tattoos. This study aimed to confirm titanium as a key response-disturbing constituent in a blue tattoo ink after Nd-YAG (1064 nm) laser treatment by animal experiments. Rabbits' backs were tattooed with four ink colours, and the Nd-YAG (1064 nm) laser was used to remove the tattoos. The response to the laser treatment in the ...

Ornamental tattooing involves the administration of exogenous pigments into the skin to create a permanent design. Our case focuses on a 62-year-old woman who presented with an inflamed enlarging nodule on her right proximal calf, which arose within the red pigment of an ornamental tattoo. The nodule was diagnosed as squamous cell carcinoma (SCC) and subsequently excised. Over the course of the...

Although methods exist for predicting the color of a spot color ink when it overprints another ink, there is a need for a simplified model for the purpose of previewing that can be used during document creations. The proposed model characterizes each spot color individually and predicts the color of overprinting solids and halftones by linearly combining the reflectances of two colors. Each ink...
