Abstract The target of this study was to identify the interactions of the compounds of printing ink and paper coating colour and their effects on the inkjet print quality. Interactions between inkjet ink solvent components and their interaction with paper coating compounds are considered significant for the final print quality. Especially, ink solvent properties play an important role in inkjet ink drying. The methods used to study these interactions are thermogravimetry (TGA) and differential scanning calorimetry (DSC), and results are analysed for correlations with print quality. The experimental material consists of both commercial and model inkjet inks, paper coating colour compounds and commercial papers. To visualize the thermal data and to combine the TGA and DSC measurements in a single plot, a representation has been used, in which the specific gravimetric (TGA) and specific energy (DSC) ratios, m1/m2 and E1/E2, corresponding to the mass loss and energy consumed per unit mass of sample, in the temperature regions T < 100°C and 100°C < T < 220°C, respectively, are plotted against each other. The determined ratios differed greatly between different model solvents and ink series. The thermal behaviour of the solvents is seen to be relevant for predicting inkjet print quality.

Compositing is an interesting strategy that has always been employed to introduce or enhance desired functionalities in material systems. In this paper, sponges containing polypropylene, lignin, and octavinyl-polyhedral oligomeric silsesquioxane (OV-POSS) were successfully prepared via an easy and elegant strategy called thermally induced phase separation (TIPS). To fully explore the behaviour of different components of prepared sponges, properties were characterized by a thermogravimetric analyser (TGA), differential scanning calorimetry (DSC), Fourier transform infrared measurement (FTIR), and scanning electron microscopy (SEM). Furthermore, wettability properties toward an organic liquid and oil were investigated. The FTIR analysis confirmed the chemical modification of the components. TGA and DSC measurements revealed thermal stability was much better with an increase in OV-POSS content. OV-POSS modified sponges exhibited ultra-hydrophobicity and high oleophilicity with water contact angles of more than 125°. The SEM revealed that POSS molecules acted as a support for reduced surface roughness. Moreover, OV-POSS-based blend sponges showed higher sorption capacities compared with other blend sponges without OV-POSS. The new blend sponges demonstrated a potential for use as sorbent engineering materials in water remediation.

The era of environmental protection and personalization has become increasingly prominent, and people not only focus on the beauty of the design, but also pay more attention to the quality of the clothing. For inkjet printing, the viscosity and surface tension of ink are major factors that affect the quality of ink-jet printing. In order to obtain a better print quality, the samples of five different viscosity and surface tension of ink were prepared respectively by changing the content of the resin and the surface active agent. Using these samples to print on the fabric by Epson printer, and to discuss the influence of the ink in different viscosity and surface tension on the ink-jet printing quality, such as apparent color depth (K / S), color parameters (L, C), permeability, clarity. The results showed that: with the increase of the ink viscosity, the apparent depth of color yield increased gradually and became darker in color. L value decreased gradually and had a increasing trend, and tends to be stable. C value increased and vividness of the color was improved. And it also had a certain impact on the infiltration resistance and clarity. Surface tension also had a significant impact on the depth of the apparent color, vividness of the color and directly affected the ink permeability and clarity.

In the process of the ink drops forming and spreading out, the viscosity and surface tension of the ink play an important role, and then the drops’ injection and printing quality will be influenced by this process. Besides, drops control technology is the key of ink-jet printing technology, and the drops’ injection state will also influence the printing quality. In order to research the influencing factors to printing quality, many samples with different performances are prepared and their drop states include speed, tail length and volume are measured with drop observatory. And then, the specimen pages include lines of different width are printed, order to assessment the printing quality comprehensively, their line width, raggedness, blurriness, density and contrast are measured. The result show that the inks with different performance show different speed, tail length and volume, and their corresponding printing qualities are different too, and there exists linear relationship between printing quality and the drops’ viscosity, surface tension and speed.

The global trend of digitization has totally varied the printing production processes. Among different printing technologies, digital ultraviolet (UV) ink-jet printing has strengths of easy to dry, printing on unsmooth surface, easy to print with different substrates and lower cost, and hence was commonly adopted by different industries. This study was to evaluate the print quality and weathering resistance of UV ink-jet printing on glass. The UV inks, from companies of AGFA and Anderson companies, and Primer adhesive and white ink from a domestic company were adopted in this study. Four types Primer were applied, i.e. without Primer, one layer of Primer, three layers of Primer, and five layers of Primer, before the print test target was printed. Two types of inks from AGFA and Anderson were used by a UV ink-jet printer to print out the test target. A spectrophotometer was used to measure the test charts, and the print quality was analyzed in terms of color contrast, solid ink density, ink trapping, dot gain or tonal value increment, gray level, etc. The experiment showed that test targets printed with two types of inks had no significant difference both on printability and print quality. However, the Anderson ink had slightly better print quality, weathering resistance, wear resistance, and adhesion compared to those of AGFA’s. Glass printed with Primer and white ink layers in advance had better printability and color quality in the experiment. Overall, UV ink-jet printing on glass had excellent printability and color performance. The results of this study can be referred by industries.

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.

Abstract The aim of this research was to investigate the influence of natural zeolite clinoptilolite used as a filler on the printabi1ity of paper and its print quality. Paper handsheets were prepared with the addition of 20% of fillers, where natural zeolite was added to calcium carbonate in different u.w.% (i.e. 20, 40, 60). Zeolite originates from the sedimentary deposit in Donje Jesenje, Croatia. Zeolite tuff is mainly composed of clinoptilolite. lts particle size distribution is broad and the structure is micro- and mezzo-porous. The addition of natural zeolite as a filler resulted in higher bulk of paper sheets and a more porous structure. Moreover, the absorption capacity and the absorption rate slightly increased. The surface roughness increased, leading to a more hydrophobic surface. Natural zeolite with its broad particle size distribution, higher amount of large particles and yellowgreen colour resulted in slightly lower opacity and ISO brightness of sheets. When used for ink jet printing, the increased amount of zeolite showed a positive influence on the print quality. Smaller wicking and bleeding effects were noticed. Paper hue did not influence the colour density of CMYK prints.
