This article reviews the use of chromatography for the separation and comparison of ink components. Thin layer chromatography (TLC) is the standard chromatographic procedure presently employed for the comparison of inks. Thin layer chromatography systems are described for the separation of different types of ink. The greater sensitivity and resolution offered by high performance liquid chromato...

Wide acceptance of inexpensive writing tablets with high functionality motivates the development of individualized, adaptive on-line recognition of cursive script. We demonstrate a lexical algorithm based on bigram matches. The solution we propose is to (i) Generate a match list by partial-word matching against a reference list in the owner's script. (ii) Identify each unknown word by eliminati...

Ink completion is a technique for suggesting characters or words to users as they write with digital ink. With a simple gesture, users can accept a recommendation and continue writing. The technique improves the handwriting experience and is very suitable to support notetaking on tablet computers and PDAs.

We report the case of a 33-year-old male who presented with a malignant melanoma on his anterior chest wall. The lesion was only found in the red ink pigment of the tattoo, as were several in-transit dermal metastases. Possible explanations include a pre-existing lesion which was seeded with red ink or the possibility of the red ink causing an inflammatory reaction leading to malignant transfor...

This paper presents an effective method to simulate the ink diffusion process in real time that yields realistic visual effects. Our algorithm updates the dynamic ink volume using a hybrid grid-particle method: the fluid velocity field is calculated with a low-resolution grid structure, whereas the highly detailed ink effects are controlled and visualized with the particles. To facilitate user ...

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...

The proposed new spectral reflection model enhances the classical Clapper-Yule model by taking into account the fact that proportionally more incident light through a given colorant surface is reflected back onto the same colorant surface than onto other colorant surfaces. It comprises a weighted mean between a component specifying the part of the incident light that exits through the same colo...

RELATED LINKS It offers excellent resolution and high contrast under a wide range of viewing angles, requires no external power to retain its image, weighs little, costs less and is remarkably flexible (literally and figuratively)-unlike today's computer displays. No wonder traditional ink on paper continues to flourish in a digital world that was expected to all but do away with it. Yet ink on...

The color inconstancy of prints is related to the ink spectral properties and the lookup table for multiink printing systems. In this paper, color inconstancy was investigated for several ink-jet printers based on their ink set and the default lookup tables. A virtual model for each printer was created to determine the range of color inconstancy that a specific ink set could achieve. The color ...
