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...

The paper presents an innovative approach to the spectral-based characterization of ink-jet color printers. Our objective was to design a color separation procedure based on a spectral model of the printer, managed here as an RGB device. The printer was a four-ink device, and we assumed that the driver always replaced the black completely when converting from RGB to CMYK amounts of ink. The col...

Graphene ink is a commercialized product in the graphene industry with promising potential application in electronic device design. However, the limitation of the graphene ink is its low electronic performance due to the ink preparation protocol. In this work, we proposed a simple post-treatment of graphene ink coating via electrochemical oxidation. The electronic conductivity of the graphene i...

Recently piezo-based ink jet printers have proven to be reliable, productive manufacturing tools particularly where expensive materials are involved. As bioengineers, we are capitalizing on the ability of piezoelectric-based drop-ondemand ink jets printers to precisely deposit a wide variety of biologically active materials to create custom arrayed libraries and patterns. These applications and...

Suibokuga is a style of monochrome painting characterized by the use of Chinese black ink (sumi), a complex interaction between brush, ink and paper, and such visual features as Noutan (shade), Kasure (scratchiness), and Nijimi (blur). In this paper we present a simple behavioural model of water and ink particles based on a 2D cellular automaton computational model, and its application to a Sui...

The purpose of this study was to investigate the effect of type of alcohols and humectants in inks formulation, and the papers surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink formulation from previous study, which contained C.I. Reactive Blue 21 Ink2 was formulated with different ...

I have implemented ink and voice annotations in DENIM, a sketch-based web site design and prototyping tool. I also performed an informal evaluation of the annotation feature with four participants, one of whom was a professional web designer. The evaluation focused on how people use ink and audio annotations to review existing designs of web sites. The participants in the experiment tended to u...

Recently, many pen-based devices have enabled people to input digital ink naturally. Often, there is smear and correction when writing. This not only makes the document dirty and look unpleasant, but also affects the handwriting recognition when recognition is called for. As the first paper to address the ink cleanup problem, we present our ink cleanup system that removes the smear and correcti...

In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. The quality of reproduction of colour images in offset printing is dependent on a nu...
