QUESTION: What is JLYT?
ANSWER: JLYT (pronounced "J layout") is a print-optimization technology that can be used for printing variable-data documents on some types of printers and digital presses made by Hewlett-Packard (HP) — most notably the HP Indigo digital press.
The abbreviation JLT is sometimes used for this format (instead of JLYT).
Like other print-optimization technologies, the JLYT technology is based on the concept that the printer/RIP will process the static information for a variable-data print run only once, instead of processing the static information over and over, once for each document in the print run. This allows the variable-data documents to print faster than they would print if a print-optimization technology were not in use.
