This study aims to analyse how inks of different colorant present unlike printing quality on selected substrates in inkjet printing. Applying Epson piezoelectric inkjet printer, experiments of printing pigment-based ink and dye-based ink on various substrates (coated art paper, porous photo paper, swellable photo paper, PP synthetic paper, xuan paper and PET-based coated film) were carried out respectively. Using digital microscope, the spreading, penetrating and distributing of ink drops were observed. Water fastness and light fastness were evaluated through aging test and water-immersing test, by measuring the decreasing of optical solid density. Taking the formula of inks and the composition of coating layers into consideration, contrast and analysis of print quality with different black inks on substrates of diverse support body were studied. The result demonstrates: Both dye-base and pigment-base inks present ideal optical density in special-purpose photo paper (swellable or porous type), exhibit distinct writing picture edge, and excellent water fastness and light fastness. While, coated art paper, PP synthetic paper, xuan paper and PET-based coated film, which shows relatively rough surface or weak ink absorbancy, are more suitable to use pigment-based ink.

Jet Printing

Cotton fabric was directly inkjet printed with reactive dye ink, the ink would appear on the permeability of the fabric, the depth of color yield is low, light fastness is poor. Pretreatment agents with different mass fractions had been used to do the pretreatment of the cotton fabric before ink-jet printing, the results showed that: when the concentration of alginate ester or seaweed was between 1.0% -1.5%, the fabrics had the high color yield and the fixation color rate of the dye was the highest. When the amount of NaHCO3 was 3%, the inkjet printing effect of cotton fabrics was the best; color fastness of colors was all good. After Inkjet printing, the best effect can be achieved by steaming the cotton fabrics under the 100 °Csaturated water vapor for 25min: the colors of black, red and yellow of the K / S value were of the maximum, color fastness was fine.

Three novel vinyl sulfone reactive dyes of various metallic salts (Na, K, Li) have been synthesized by coupling 1-amino-phenyl-4-beta hydroxyethyl sulfone sulfate ester with 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid (H-acid). The reactive dyes were then purified using ultrafiltration (UF). The ultrafiltrated dyes of the various metallic salts were characterized by their spectrophotometrical data using Ultra Violet-visible (UV-vis), Fourier transform infra-red and optical emission spectroscopy, X-ray diffraction, and elemental analysis. The purity of the dyes was checked by Thin Layer Chromatography (TLC). The solubility characteristics of the various salts of the ultrafiltrated reactive dyes were assessed and compared with the non-ultrafiltrated reactive dyes of the same salts. The dyes were characterized and applied to cotton, wool, and nylon 66 by exhaustion (dyeing). Novel water-based reactive ink-jet inks were prepared with the ultrafiltrated reactive dyes of the various metallic salts. Their suitability for digital printing applications was examined by using a digital printer on suitably pretreated cotton samples. Color and fastness properties measurements were performed for both the dyed and digitally printed samples. K/S values of the dyed samples were higher than those of the digitally printed ones, whereas K/S values of the samples dyed with the ultrafiltrated dyes were much higher than those of the non-ultrafiltrated dyes. The other coloristic co-ordinates L*, a*, b*, C*, and ho were in line with strength changes of the dyes before and after UF. The dyed and digitally printed samples had excellent wash and good light fastness properties. UF slightly improved the fastness properties of the dyed samples.

AbstractDipole emission pattern imaging experiments on single chains of common conjugated polymers (solubilized poly phenylene vinylenes) isolated by ink-jet printing techniques have revealed surprising uniformity in transition moment orientation perpendicular to the support substrate. In addition to uniform orientation, these species show a number of striking differences in photochemical stability, polarization anisotropy,[1] and spectral signatures[2] with respect to similar (well-studied) molecules dispersed in dilute thin-films. Combined with molecular mechanics simulation, these results point to a structural picture of a folded macromolecule as a highly ordered cylindrical nanostructure whose long-axis (approximately collinear with the conjugation axis) is oriented, by an electrostatic interaction, perpendicular to the coverglass substrate. These results suggest a number of important applications in nanoscale photonics and molecular-scale optoelectronics.

Abstract The moist heat (80°C and 65% relative humidity) and light (xenon arc lamp) treatments of accelerated ageing were applied to investigate the colour stability of offset and electrophotographic prints on papers made of virgin and I 00% recycled fibres. The prints were evaluated using spectrophotometric measurements and additional colour differences calculations. In addition to the colour differences, the 2D and 3D colour gamuts are presented. The results reveal the different colour stability of prints. The effect depends on the type of accelerated ageing, printing technique, composition of ink and paper characteristics. Moist heat ageing has less influence on colour stability than light ageing. The electrophotographic prints show better ageing resistance than offset prints. The intluence of ink on print light fastness is considerable. Azo pigments in magenta and yellow have lower light fastness than phthalocyanine pigments in cyan or carbon black. The surface coating has an intluence on light fastness of prints. Meanwhile, prints on recycled papers show similar colour stability compared to prints on papers made of virgin fibres
