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 […]

Slurring refers to a distortion in printed images caused by specific conditions during an offset printing press run. This distortion makes dots or type appear shifted, either laterally or circumferentially, depending on the direction of the slur. Each type indicates distinct issues that require targeted solutions. Slurring in the […]

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 […]
