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 […]

sustainable eco ink for protecting nature — 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 […]

Plate Blinding Plate blinding in offset printing is a situation when printing plate’s non-image areas (the areas that are meant to remain ink-free) become covered or clogged with ink, causing them to inadvertently accept ink. This results in unwanted marks or faded images being printed in areas where they should […]

rollers in the offset printing press — The ink roller train consists of an ink fountain with ink keys, an ink distribution blade and roller, a ductor roller and alternating hard and soft distribution rollers. Proper ink distribution begins at the ink fountain. If the blade is nicked, the roller surface scored or pitted, or the fountain […]

Color Bar — Density is the level of darkness in a negative or positive film or print,so the measurement of density is called densitometry. An instrument called a densitometer is used to measure the density. Any printing process from the most simple black and white work to complex color work will benefit from […]

influence on electrostatic charge on printing paper — Offset printers know very well what this problem represents: printing sheets stick together because they are electro-statically charged. This condition may result in feeder trip-offs, print voids from surface contamination, ink offset, or poor sheet jog in the delivery. Static electricity arises from either an electron deficit (positive charge) or […]
