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 ...

The purpose of this study was to investigate the effect of the structure of reactive dye on cotton ink-jet printing. Cotton fabric was printed upon with three commercial cellulosic reactive dyes which are based on the similar chromophore and possess different numbers of reactive and anionic groups. Colour yield and absorbed dye fixation of the printed cotton were evaluated at various pHs. The i...

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...

A colour ink jet printing with improved water fastness property was produced by using of special component in the ink’s formulation. In this study, the water fastness of ink jet prints which used acrylic/nano-silver resin nano-composite ink instead of conventional resin in ink’s formulation was examined. The nano composite resin was prepared via miniemulsion polymerization of acrylate monomers ...

This paper presents experimental observations and a theoretical analysis of the operation of drop-on-demand piezoelectric ink jet devices. By studying experimentally the dependence of several operating characteristics on the length of the cavity in the nozzle of an ink jet device, we have gained insight into the physical phenomena underlying the operation of such a device. It is concluded that ...

We formulated a latex ink for ink-jet deposition of viable Gram-negative bacterium Gluconobacter oxydans as a model adhesive, thin, highly bio-reactive microstructured microbial coating. Control of G. oxydans latex-based ink viscosity by dilution with water allowed ink-jet piezoelectric droplet deposition of 30 × 30 arrays of two or three droplets/dot microstructures on a polyester substrate. P...

This study aims at exploring ink spreading, which causes significant colour deviations in ink-jet printing. We present a method for investigating this phenomenon by considering only a limited number of cases. Using a combinatorial approach based on Pólya’s counting theory, we determine a small set of ink drop configurations which allows to deduce the ink spreading in all other cases. This impro...

Ink-jet printing is an important process for placing active electronics on plastic substrates. We demonstrate ink-jet printing as a viable method for large area fabrication of carbon nanotube CNT thin film transistors TFTs . We investigate different routes for producing stable CNT solutions “inks” . These consist of dispersion methods for CNT debundling and the use of different solvents, such a...

The purpose of this study was to investigate the effect of the reactive dye structure and type of penetrant in ink formulation on paper ink-jet printing. Different type of papers, which have same grammage was printed upon with three commercial reactive dyes, CI Reactive Blue 49 Ink 1, 4, CI Reactive Blue 21 Ink 2, Ink 5 and CI Reactive Blue 19 Ink 3, Ink 6, which are based on different reactive...
