Heatset Printing

Many heatset printers also print newspapers. But in addition, they also print flyers, glossy magazines and other high quality work. This is because the process allows for higher quality papers such as glossy and semi-coated papers.

Since ink poorly absorbs into a glossy coated paper, it must dry on the surface. The plus to this is that it can produce a much sharper image. The downside is that you must find another way to dry the ink. Heatset ink is made of ingredients that will quickly dry under extreme heat.  So to dry the ink you must add a few components to the press.

Coldset Printing

Ever get dirty hands from handling a newspaper? Sometimes ink will rub off on your hands. That’s coldest. The oils in the ink never completely dry – hence the smell and scuff from newspapers.

Coldset PrintingMany newspaper printers nowadays use the coldset form of printing. This basically means that they do not apply any heat to the ink to make it dry. It dries primarily through absorption into the paper and evaporation into the air.
