Understanding Coldset 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 ink |
Web Offset Printing |
Coldset offset printing is a process by which the ink dries gradually through evaporation and absorption into the paper. | Most commonly used on uncoated paper like newspaper. | Coldset is one of the more economical forms of printing that allows multiple webs to run concurrently, while using less expensive uncoated paper and energy to produce the product. |

Heatset ink |
Web Offset Printing |
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. | Coated (Glossy) paper such as the paper used in magazines and catalogs | Heatset
printing has become more popular recently because advertisers are more often turning to supplemental inserts and direct mail campaigns that use glossier paper. |
