Web offset printing machine is a form of offset printing in which a continuous roll of paper is fed through the printing press. Pages are separated and cut to size after they have been printed on web offset machine. Web offset printing is used for high-volume publications such as mass-market production of books, magazines, Supplements & newspapers. There are two methods of web offset printing, known as heat set and coldset (or non-heatset).

Cold set Web offset printing (also known as non-heatset) is a web offset printing process in which ink is allowed to dry naturally through evaporation and absorption. In the alternative method, heatset Web offset printing, ink is dried rapidly by forced-air heating. Web offset printing is a printing process in which a continuous roll of paper is fed through a offset printing press.

Cold-set Web offset printing presses are available from 20 inch to 22.75 inch wide range cut off sizes. This of course varies as large newspaper presses today are also mostly "cold-set." These web offset printing machines have been used mainly by the Newspaper printer to print newspapers & supplements, Book Publishers to print magazines, School Books etc.

The coldset web offset press manufactures today are even gearing their webs to compete against heatset web offset and sheet fed offset printing machines. Their motto; "Why print 5,000 impressions per hour when you can print upto 30,000?" It is because of this shift that the smaller press is being equipped with press consoles, IR or UV driers, better registration systems, etc.
