Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Abstract—The objectives of this research are to produce prototype coconut oil based solvent offset printing inks and to analyze a basic quality of printing work derived from coconut oil based solvent offset printing inks, by mean of bringing coconut oil for producing varnish and bringing such varnish to produce black offset printing inks. Then, analysis of qualities i.e. CIELAB value, density v...

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...

The technology of the used machines and tools in printing technology and in the offset printing has reached the stage when, technologically, it is very difficult to raise the printing quality with the up to now used production materials, which the world market demands more and more [1, 2]. Because of that the producers of the printing materials and inks invest great means in the development of ...

The flexographic printing is the fastest growing printing technique nowadays [1]. The principal advantages of flexography are reflected in the markets where it is most often used. The advantages of flexographic printing are low cost and short circle time, precise ink transfer with minimum on-press adjustments, and ability to print one layer and laminate another layer over it in a continuous pro...

During the last couple of years several ink manufacturers have presented metal nano-particle inks for inkjet printing. These inks provide low resistances on plastic and paper substrates, thus enabling manufacturing of high-conductivity conductors that could be used in circuit boards. Inkjet printing of a commercial silver nano-particle ink on paper and plastic substrates has been investigated. ...

printing and packaging industries make three phases of solid, liquid and gaseous contaminants which can cause very dangerous problems. the presence of alcohols, inks, and cleaners can result in massive range of industrial pollutants. always respiratory problems, fatigue, dizziness, weakness, abnormal behavior, memory impairment, insomnia, loss of appetite, and impaired vision and hearing and ca...

Until the middle of this century, fats and oils are the major raw material source for paints, coating and lubricating applications. These markets are completely taken over by petroleum based stocks due to their abundance and versatility. However, recent public awareness to use environmentally acceptable products that minimize pollution, are compatible to human health and readily biodegradable c...

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...
