What is coldset printing?
Coldset printing is a form of offset printing in which the ink dries by being absorbed into the paper. This is in contrast to heatset printing, in which the printed pages must be run through dryers to evaporate the solvents and set the inks. Coldset printing is used on uncoated papers like newsprint.

What is the difference between coldest and heatset offset printing?
Coldset and heatset both refer to a process used to dry ink after it has already been applied to the paper. With both coldest and heatset offset printing the paper is run through the printing press in the same way. The difference comes when it is time for the ink to dry.
Coldset printing is most commonly used on uncoated paper stocks like newsprint. Since the ink is not set immediately, there is always a little bit of residue that remains on the paper. This is what you sometimes get on your hands if you have been holding a newspaper.
What is heatset printing and how does it work?
Heatset printing is the process by which ink is dried by running the printed paper through an oven immediately after ink is applied by the printing units. As the paper passes through the oven, the oil based solvents in the ink reach a “flashpoint” or evaporation point.
