The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

By introducing of digital techniques, forensic document examiners has been encouraged to work with better accuracy in non-destructive ways. The aim of this study was to present a non-destructive, accessible, economic (affordable), user friendly, portable, useful and easy technique for specifying the order of crossing lines of ink stroke and printed text. The intersections of LaserJet and In...

We present techniques that allow sharing of standardized digital ink in a heterogeneous collaborative environment. We explore the use of W3C InkML (Digital Ink Markup Language) and show how it is more flexible and suitable than other digital ink formats for this purpose. We discuss different possible digital ink sharing schemes using InkML and describe pros and disadvantages of each. We present...

We review the phenomena having an impact on the interaction between light, paper and color halftones. They comprise surface reflections and refractions at the air-paper interface, propagation of light within the paper, internal reflections at the paper-air interface, as well as ink spreading and trapping. We introduce basic notions from radiometry and optics, such as the definitions of radiant ...

BACKGROUND India ink microscopy on cerebrospinal fluid is still utilized in resource limited settings for the diagnosis of cryptococcal meningitis despite its poor sensitivity. We hypothesized that staining fungal nucleic acids with fluorescent dyes instead of the capsule with India ink might improve sensitivity for the diagnosis of cryptococcal meningitis. METHODS We enrolled 96 HIV-infected...

One of the complex tasks in mass production of RF electronics is printing the communication antenna using electrically conductive ink. For example, this is very common for radiofrequency identification (RFID) tags. Electrical properties of the ink are mostly determined by conductive (e.g. silver) particles mixed into the ink solution and the way they ‘connect’ in the cured ink. It is also desir...

This paper is divided into two parts with the aim to compare visco-elastic structure relaxation of a presheared offset ink with observed ink tack development on a representative absorbent multi-coated paper. The methods used include oscillatory and shear rheometry in part I, and comparison with the SeGan Ink Surface Interaction Tester (ISIT) in part II. By diluting the ink with mineral oil, a p...

We investigated the use of India ink as an indicator of root canal sealing ability. Sealing ability is one of the most important factors required of root canal cements. Various dyes have been used for this purpose. Methylene blue, radioisotopes and India ink have all been tried. However, there is no evidence that India ink is suitable as an indicator. We measured the particle size distribution ...

We fabricated two-color luminescence ultrathin films (UTFs) composed of the layered double hydroxide host-aggregation-induced emission guests by LBL assembly. The fabricated UTFs were simple, tunable, controllable and highly luminescent. Moreover, reversible thermochromic luminescence further exhibited their potential in practical applications.
