Interpress is a high-speed, large-format printing process developed in the early 1970s by Xerox. It uses a special paper that is coated with a thermosetting resin. The paper is fed through a heated fuser roll that melts the resin, bonding the image to the paper.
Interpress was originally developed for use in print shops and commercial printing operations. However, it has also been used for the printing of books, magazines, and other publications. The process is well suited for print runs of several thousand copies or more.
The major advantage of Interpress is its speed. It can print up to 150 pages per minute, which is much faster than conventional offset printing. Interpress is also capable of producing very high-quality prints, with sharp images and smooth tones.
Another advantage of Interpress is that it uses less paper than offset printing. This is because the printing plates are not made from paper, as they are in offset printing. Instead, the plates are made from a material called photopolymer, which is much thinner than paper.
Interpress was an important innovation in the world of books and printing. It allowed for books to be printed with more accuracy and detail than ever before, and made it possible for publishers to produce higher quality books. This in turn led to a boom in the book industry, as more people were able to afford to purchase books. Interpress also made it possible for books to be printed in multiple languages, which made them more accessible to a wider audience.
One of the main advantages of Interpress is that it can significantly reduce the cost of printing books. This is because the digital files used to create Interpress books can be stored and reused, meaning that there is no need to create new printing plates for each printing run.
