Effect of Paper Surface Characteristics on Dot Gain in Ink-Jet Printing

Four kinds of ink-jet papers with different surface characteristics are chosen in this paper, by the ink-jet proofing experiments, the influence of surface characteristics to dot gain is studied, and the law of dot gain with paper surface characteristics is discussed. During the experiment, surface properties including absorbency, gloss, roughness and whiteness are tested firstly; then, the standard wedge of GATF is printed on these papers in the same printing conditions; finally, the dot gain is tested by SpectroEye. After experimental data processing and analysis, dot gain curves of different ink-jet papers are concluded, the law of dot gain with ink-jet paper surface characteristics is summarized. The results show that dot gain is different in different paper, the evaluation of 3# is the best; dot gain is also different with different colors in the same paper, and it is serious in cyan but light in yellow; the biggest dot gain appears in different contrast with different colors, cyan appears near the 65% dot area.

The influences of the paper properties on ink-jet printing quality are very complex. In order to predict the printing quality quickly and accurately, it is necessary to establish a mathematical model and an evaluation system, based on which we can estimate the paper used for ink-jet printing is suitable or not. In this paper, five kinds of ink-jet papers with different properties were chosen, and the properties including brightness (X2),gloss(X3),roughness(X4),air permeability(X5) and absorbency(X6), were tested; then ink-jet printing in the same conditions was carried out and different printing parameters were tested, including solid density(D),dot-gain(DG),print contrast(K)and hue(H). Through combining analysis of each single printing quality parameter with some paper properties by using PCA of SPSS, the correlation functions D/DG/K/H(X2, X3, X4, X5, X6) were obtained. Meanwhile, a comprehensive function Y(D, DG, K, H) involving the printing quality parameters was achieved through synthesis data processing of SPSS. This study shows the influences of paper properties on the printing quality parameters and their corresponding weights, and it also proposes a prediction model of paper printability, which can provide a theory reference for printing work in ink-jet printing.

Ink-jet printing is a non-contact printing, drops are jetted on the substrates to form images through the nozzles at a certain speed. Dot is the smallest unit in printing; the qualities of printing are seriously affected by dot gain. Ink spreading and penetration are discussed in this paper, influences on dot gain in ink-jet printing are studied, the original Young's equation and Washburn formula are theoretically amended, more scientific and rational models and formulas are obtained in the actual process of ink-jet printing, which offers reference standard and theoretical basis to improve the quality of ink-jet printing.

Based on the experiment, this paper used principal component analysis and multiple regression analysis to establish a fuzzy evaluation system between the paper performance and print qualities. Five kinds of ink-jet paper with different surface characteristics were chosen in this paper to test their properties including absorbability, gloss, roughness, whiteness etc. During the same printing condition, using the digital proofer of EPSON Stylus Pro7880c, the standard wedge of GATF, solid color lumps and standard lines were printed on these paper samples; dot gain and solid densities were tested by SpectroEye, then contrast-K was calculated, the qualities of lines were analyzed with QEA image Analysis. Finally, paper surface characteristics were analyzed with principal components analysis, and definition of printing was analyzed by QEA Image Analysis, correlation between paper basic performance and the characteristics of printing qualities, such as dot gain, solid density, definition and contrast-K, and an integral evaluation function and a model were established. When evaluating on paper, as long as its surface characteristics were tested, the printability of different paper can be evaluated in a fuzzy and integral way through the calculation of the model and evaluation function. This work offers a certain theoretical reference and practical guidance to the selection of ink-jet paper and the improvement of ink-jet qualities.

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.
