The largest press that was available to print the movie-poster blocks was originally used for making stereotype molds, called flongs. First, a forme, or typeset copy and imagery (often an advertisement), would be locked up in the press. Next, heat resistant, yet pliable, paper would be pressed very tightly over the forme, while being run through this press, to take on the reversed impression of the type and imagery, thus making a mold. Molds, also known as flongs, were much less expensive to distribute than a heavy metal plate, via mail, to newspapers and other publications across the country. Each newspaper or printer that received a flong would pour molten metal into the mold, to make a metal plate, called a stereotype, that contained the same content as the original forme. This stereotype, usually advertising something that was available nationally, such as a new movie, or automobile, would be inserted into a larger forme, most likely a newspaper, and printed. Once the content of a stereotype was no longer useful for printing, the plate was melted and recast in a different flong. In the twenty-first century, when flongs are no longer used, such a press also makes a useful printing press for large blocks.
