Page "Phototypesetting" Paragraph 4

To provide much greater speeds, the Photon Corporation produced the ZIP 200 machine for the MEDLARS project of the National Library of Medicine and Mergenthaler produced the Linotron.

The ZIP 200 could produce text at 600 characters per second using high speed flashes behind plates with images of the characters to be printed.

Each character had a separate xenon flash constantly ready to fire.

A separate system of optics positioned the image on the page.
