prosessblekk

Prosessblekk is a term used in the Norwegian printing industry to refer to inks designed for processing efficiency in high-volume production. The name combines "prosess" (process) and "blekk" (ink), signaling an emphasis on reliable performance throughout a production run. The concept covers several ink families used in commercial printing, packaging, and security applications, including offset lithography and some digital-analog hybrid processes.

In general, prosessblekk refers to inks formulated for stable color reproduction, rapid drying, good on-press flow, and substrate compatibility, with a focus on minimizing makeready time and waste. Typical compositions include pigments or dyes dispersed in a resin-based binder, with a water or low-VOC solvent vehicle and various additives to control viscosity, drying, leveling, and slip. Performance characteristics sought include tinting strength, color gamut, adhesion, rub resistance, and resistance to set-off.

Environmental and safety considerations are common, with manufacturers pursuing lower volatile organic compounds, reduced odor, and compliance with local and international regulations. Because the term is not standardized across brands, specifications for prosessblekk can vary by supplier, press type, and application. See also: printing ink, offset printing, ink chemistry.
