The penetration of ink into the paper affects the final appearance of printing and the amount of ink usage. The main aim of this experiment was to investigate the efficiency of coating speed on surface properties and ink penetration and to characterize the penetration depth through quantitative analysis by laser scanning confocal microscope (LSCM). The results indicated that the surface properties of coated paper could be adjusted and improved by increasing the coating speed. With the increasing of coating speed, ink penetration depth declined and ink penetration uniformity increased. It could be concluded that the coated paper with high coating speed compared with low coating speed resulted in lower ink usage and better printability on the condition of same print density.

The objective of this experiment was to investigate the influence of coating solid on surface properties and ink penetration and to characterize the penetration depth through quantitative analysis by laser scanning confocal microscope (LSCM). Fluorescent ink was used to observe and characterize ink penetration and distribution by LSCM. The results implied that the surface properties of coated paper could be adjusted and improved by increasing the coating solid. With the increasing of coating solid, ink penetration depth declined and ink penetration uniformity increased.

Printing Speed

What happens in the paper surface about ink absorption is of great important for appearance of final printing. The aim of this experiment was to investigate the influence of printing pressure and printing speed on ink layer thickness transferred onto coated paper through quantitative analysis by laser scanning confocal microscope (LSCM). Meanwhile, the influence of printing pressure and printing speed on print density and print gloss were obtained. The results implied that higher printing pressure resulted in higher ink layer thickness, print density and print gloss when printing pressure is less than 700N, but higher printing speed resulted in lower ink layer thickness, print density and print gloss when printing pressure is constant. It could be concluded that the coated paper with high printing speed compared with low printing speed resulted in lower ink absorption, lower print density, lower print gloss and worse printability on the condition of same printing pressure.

Distribution Uniformity

Cutting is a relative accurate method in the literatures about ink penetration measurement at present. But cutting may bring some damages to paper, which reduces reliability of measurement result. The objective of this experiment was to investigate the influence of coating thickness on ink penetration and characterize the penetration depth through quantitative analysis by Laser Scanning Confocal Microscope (LSCM). Fluorescent ink was used to observe and characterize ink penetration by LSCM. Three-dimensional images of ink pigment penetration were obtained by reconstructing all XY plane images. The results implied that it was reliable and effective method using LSCM to characterize the ink penetration depth and distribution uniformity. It could be concluded that the print quality could be adjusted and improved by increasing the coating thickness.

Laser Scanning Confocal Microscope

The staining of neurons with silver began in the 1800s, but until now the great resolving power of the laser scanning confocal microscope has not been utilized to capture the in-focus and three-dimensional cytoarchitecture of metal-impregnated cells. Here, we demonstrate how spectral confocal microscopy, typically reserved for fluorescent imaging, can be used to visualize metal-labeled tissues. This imaging does not involve the reflectance of metal particles, but rather the excitation of silver (or gold) nanoparticles and their putative surface plasmon resonance. To induce such resonance, silver or gold particles were excited with visible-wavelength laser lines (561 or 640 nm), and the maximal emission signal was collected at a shorter wavelength (i.e., higher energy state). Because the surface plasmon resonances of noble metal nanoparticles offer a superior optical signal and do not photobleach, our novel protocol holds enormous promise of a rebirth and further development of silver- and gold-based cell labeling protocols.
