graphic diagram of deinking — The ability to deink paper – in other words, to separate ink and coatings from it – is crucial for sustainable recycling of it. Good deinkability is a prerequisite for using used paper to make graphical papers and hygienic paper products. Effective processes are available today for removing aqueous coatings […]

eco printing inks — Some of the pigments used in ink contain metallic substances which are harmful to human health and the environment such as cadmium, chromium, lead and mercury. Conventional printing inks are petroleum – based and used with alcohol-based solvents. As alcohol and petroleum evaporate Volatile Organic Compounds (VOCs) are emitted. VOCs […]

Dot Distortion — One talks of slurring whenever the geometry of the halftone dot changes. The printed image then appears to be displaced. The round halftone dot assumes an oval form. Two kinds of slurring exist – on the one hand, in the direction of printing (circumferential slurring), and on the other hand, […]

emulsifion — Emulsion is a mixture of ink and dampening solution. In this process, dampening solution is distributed evenly throughout the ink in small droplets. The proportion of water in a “stabile emulsion” is around 20 %. If higher, then the ink’s splitting properties are reduced, and the ink flow is interrupted. […]

chalking — If the ink dries too slowly in the stack, one can speak of a lag in drying time. This may lead to an ink rub-off of the print during print finishing or during transport. The interaction between ink, additives, and dampening solution is usually to blame for lags in drying […]
