Answer:
Hot and cold type were both used in the early 1900s to print newspapers; however, cold type became the industry standard around 1968.
Step-by-step explanation:
In the 1960s, cold type started to become the norm in the newspaper industry, which is neither cold nor typing, but rather phototypesetting. Basically, machines print text on photographic paper, then wax is applied to one side, hand-trimmed and positioned on a page-size template.
Next, a negative of the template is created, then the industry exposes the negative to an aluminum plate, and the plates are applied to a printing cylinder on the press.
