Vanliga arkoffsetfärger innehåller pigment, trioglycerid, mineraloljor eller vegetabiliska oljor, naturliga hartser, alkyder och tillsatser såsom torkmedel, antioxidanter och vaxer.Tryckfärger för olika ändamål torkar genom skilda processer. Arkoffsetfärger torkar i två steg. Först sker oljeabsorption och sedan sker en kombination av oxidation och polymerisation. I detta steg är det bindemedlet och oljorna som förlorar dubbelbindningar, kortare molekyler reagerar och bildar längre molekylkedjor, vilket resulterar i att färgen torkar. Den kemiska torkningen initieras av luftens syre.

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.
