It describes each component element of Chinese ink painting in detail. Firstly, this paper presents brush emulation based on physical calculation. The brush model comprises a spine skeleton wrapped up a smooth surface which can be deformed through constrained energy minimization. The model can bend the skeleton and change the shape of the tuft when there is a force applied on the brush. Then, i...
An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. Finally, the substrate acts as a receiver of the inks and forms the images. Ink setting on the substrate is a compl...
It is well documented that plastics surface modification techniques can greatly improve the acceptance of a wide variety of coatings, adhesives and inks for improved decoration, painting and adhesive assembly. By increasing the hydrophilic characteristics and surface-free energy of plastics, bond strengths can be improved dramatically. It is theorized that interlayer adhesion between decorating...
Pen-based computing has and continues to become accepted and increasingly used. Hardware and software vendors have typically stored and represented digital ink using proprietary or restrictive ink formats, and have provided software development toolkits to access or manipulate ink for user development on their devices. The variety of digital ink formats and device-dependent software toolkits ha...
This paper presents an approach for extracting and segmenting tables from Chinese ink documents based on a matrix model. An ink document is first modeled as a matrix containing ink rows, including writing and drawing ones. Each row consists of collinear ink lines containing ink characters. Together with their associated drawing rows, adjacent writing rows having an identical distribution of wri...
By printing a variable number of droplets onto the same pixel location, ink jet printers produce pixels at variable dot-sizes yielding several darkness levels. Varying the number of printed droplets affects the ink volume deposited onto the substrate. In the present contribution, we explore the possibility of producing accurate spectral reflectance predictions at all pixel dot-sizes. For this p...
Near infrared spectra combined with partial least squares were proposed as a means of non-contact analysis of the adsorptive ink capacity of recording coating materials in ink jet printing. First, the recording coating materials were prepared based on nano silica pigments. 80 samples of the recording coating materials were selected to develop the calibration of adsorptive ink capacity against i...
There have been recent improvements in document technologies like the standardization of object interfaces to access and manipulate the properties of web documents. There has also been significant progress in pen based computing for recognition of digital ink in desktops, tablets and handheld devices. These have necessitated a need for further research on annotation architectures for digital do...
A novel triarylboron compound, MPB, exhibiting reversible thermochromic dual-fluorescence in solid-state polymers and in liquid solvents was designed and synthesized. The fluorescent solid-state polymer with MPB can serve as a highly sensitive self-reference temperature indicator with a concentration independent feature.
