Microengineering of Ceramics by Direct Ink-Jet Printing

A modified piezoelectric drop-on-demand ink-jet printer was used to build 3-D ceramic structures with cavities and overhangs by direct ceramic deposition. Inks in the form of zirconia and carbon suspensions were prepared with suitable viscosities and surface tensions. The multinozzle printer was used to microengineer small components in which support structures were created from the carbon ink and the carbon was removed after pyrolysis of the organic vehicle but before sintering the zirconia. The viability of this process is discussed in terms of machine limitations and ink drying problems.

Colour management in digital textile printing

On the basis of simulated prints, a customer can decide on the colour appropriateness for a selected pattern. This article presents the possibilities and correct procedure for colour management application in the field of digital printing onto a textile substrate. The aim of the research was to establish whether long‐term and expensive pre‐ and after‐treatments can be avoided with the help of an appropriate development of printer profiles. The latter would be conducted through a print simulation on paper printed with a Canon laser or ink‐jet printer. The results have confirmed that a print simulation on paper can be conducted with both printers, while a Canon ink‐jet printer offers better results. In addition, by calculating the colour inconstancy index CMCCON02, the illuminant influence on the colour change of substrates under five different illuminations was determined. The results showed that simulated colours should be compared with original colours under daylight illuminants (D50, D55 and D75), while indoor illuminants A and F2 are not appropriate for a comparison, especially in the case of simulation with a Canon ink‐jet printer (CMCCON02 index >5).     

Ink-jet printing of micro-emulsion TiO2 nano-particles ink on the surface of glass

A self-cleaning ceramic ink that contains nano-titanium dioxide was formulated. The nano-titanium dioxide was generated through the micro-emulsion process. The physical properties such as surface tension and viscosity of the prepared ink were evaluated. The ink-jet printing was carried out with an Epson Stylus Photo P50 printer on microscope glass slides. The print was set to 1, 3 and 5 runs in order to evaluate variations in wettability and resulting self-cleaning properties with varying thicknesses of the printed film. Following initial drying of the printed self-cleaning microscope glass slides; they were heat-treated at 400 °C. The SEM analysis and contact angle measurements of the printed microscope glass slides were carried out. The thicknesses of the raw printed self-cleaning ceramic inks were increased linearly with the number of printing runs. Ultimately, the results demonstrated that the direct ceramic ink-jet printing method can be used to produce a self-cleaning film on the glass.

A custom ink‐jet printing system using a novel pretreatment method

A low‐cost and environmental‐friendly direct dye‐based ink‐jet printing system was developed. A novel ink‐jet pretreatment method was employed, in which the cationic fixing agent, Matexil FC‐ER, was applied as the colourless fixing ink and applied only on image areas of the fabric by ink‐jet printer. It was found that this new pretreatment method could more effectively enhance the colour strength and improve the wash fastness (greyscale ≥ 3) when compared with traditional exhaust application. The cross‐staining of non‐image areas of fabric was also apparently decreased using this new method. The light fastness of ink‐jet pretreated samples was slightly reduced as the presence of Matexil FC‐ER made dyes more sensitive to light.     

Printability of functional inks on multilayer curtain coated paper

Printability of functional inks on multilayer curtain coated substrates was investigated. The inks represent those commonly used to produce solution processable electronic devices, such as organic transistors. The substrate, which combines sufficient barrier and printability properties for printed functional devices, was manufactured utilizing high speed curtain coating technique. The coating structure consists of a mineral pigment layer coated on top of a barrier layer. The combination of the two layers allows for controlling the absorption of ink solvents. By adjusting the thickness, porosity and surface energy of the top-coating the printability can be tuned for various functional inks. Focus was set on printing conducting silver and carbon inks, both with nano- and micrometer sized particles, as well as printing of an organic semiconductor, poly(3-hexylthiophene). The pore volume in the top-coating determined the spreading of the micrometer sized silver ink as well as the amount semiconductor per area required, whereas the pore size was the determining factor regarding penetration of the nano-sized silver ink. As a proof of concept hygroscopic insulator field effect transistors were printed on the multi-layer curtain coated paper using a custom-built roll to roll hybrid printer.     

Development of Ceramic Inks for Direct Continuous Jet Printing

A ceramic ink that contains 30 vol% of zirconia in butyl acetate and 2 wt% of a commercial oligomeric dispersant is considered. The dispersion and viscosity of this ink was optimized in previous work; however, its conductivity is too low for continuous ink-jet printing. The conductivity has been improved by the addition of ethanol and ammonium nitrate, but this addition detrimentally affects the dispersion, viscosity, and surface tension of the ink. This problem has been largely overcome by reducing the amount of ceramic in the ink. The ceramic inks that have been developed are tested in a pressurized, continuous ink-jet printer, and, depending on their performance, the ink composition is modified further.
