Printing Ink

The physical structure and chemical properties of coating layer have an important influence on transferring and setting of the printing ink. In this study, the effect of pigment on coating layer structure and surface properties was investigated. The surface topography was explored using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The findings indicated that the pigment affected the pore size, depth and distribution of the coated paper surface. The conclusions were drawn that coating could improve coating surface topography and calcium carbonate pigment compared with kaolin pigment was not good to the paper surface properties, which resulted in high roughness, low paper gloss, high ink absorption and low paper surface efficiency.

AbstractCoatings are generally applied for opacity, smoothness and gloss on the paper surface. Pigments such as CaCO3, Kaolin-Clay and Zeolite are used, and natural or synthetic binders are used. In this study, coatings using the CaCO3, Kaolin-Clay and Zeolite pigments on 80 gr/m2 high grade papers were made. PVOH was used as binder. Following coating, papers were processed through supercalendering and printed with inkjet printer. Using INGEDE method 11p. recycling process printed papers were deinked. The optical properties of the recycled papers obtained after the deinking treatment, were compared with the unprinted papers. At the end of the study, the effect of coating on paper surface and the recycling performances of the inkjet printed papers were revealed. It was determined that the papers in which zeolite was used as a pigment were better, in terms of both surface properties and recycling performance when surface properties and recycling performance of coated papers were examined. When all the results were compared, it was found that the performances of coatings for which zeolite was used were much better than coatings such as CaCO3 and Kaolin-Clay, both in terms of surface coating properties such as opacity, roughness and gloss and recycling results such as brightness.

The Impact

The influence of screening process parameters on paper properties produced from wastepaper. Wastepaper processing is of pivotal importance for environmental protection; it is also crucial for the economy and the management of raw materials. Not only does recycling save space at landfills, it also saves an extremely valuable raw material used for paper production, i.e. wood. Unlike primary pulps, however, wastepaper contains much more than just cellulose fibres and fillers. The fact that recycled paper contains many contaminants, such as metal staples, paper clips, plastic film, glass fragments, and others, makes it necessary to develop a much more complex pulp preparation systems compared to the ones used for primary pulps. Contaminants affect not only the usable quality of paper made of wastepaper, but also cause the wear and tear of paper processing equipment. Thus, the purifying and screening of secondary pulps for further processing is very important. Considering the above, the authors’ objective was to study the impact of the width of screen slots on paper properties if produced from screened wastepaper pulp. Paper strength and paper surface properties were used as the main evaluation criteria. White and mixed wastepaper was used as research material. Based on the tests, the screen slot width was found not to have any significant impact on either paper mechanical strength or paper surface properties.

Practical Guidance

By experimental methods, the influence of paper's properties on solid ink density and color reproduction results of digital prints was investigated, and different printing requirements on paper surface properties are analyzed. Different categories of paper were used, of which whiteness and smoothness was analyzed firstly, and then were output by same test target. Result shows that the paper's properties will impact on print quality to some extent, different paper should be taken for different images. The results of this paper has some practical guidance for printing companies, which can be used to research the printability of printing inks and papers, optimize printing process, improve printing quality, and provide method of standardization of process control.

Subsequent Modification

The surface properties of fibers play critical roles in many applications such as wicking, soil resistance, adhesion, and bio-compatibility. This paper will discuss a new approach to surface modification in which polymers are grafted to naturally occurring graft-sites on the substrate. The surface modifying polymers contain a large number of new graft-sites, thus amplifying the potential graft-sites up to several thousand-fold. Subsequent modification of the graft-site amplifying polymer can be used to alter the surface charge, wettability, and dye-uptake. Critical features of this technology will be presented along with specific examples.
