The development of the optical character reading (OCR) machine for high-speed code marking and sortation of letter mail has led to the need for a high-speed method of printing the phosphorescent code marks used by the mechanised letter sorting machines. This paper looks at the requirements for the printing system, the method adopted and the results achieved.
