Modern 3D representation of a Key Line Drawing (KLD) showing precise cut lines, crease lines, and glue flap boundaries overlaid on a folding carton.
A key line drawing in packaging (KLD in Packaging) is a flat, 1:1 scale technical drawing of a packaging structure showing cut lines, crease lines, perforations, and glue flaps. Most converters treat KLD and dieline as synonyms. Die-makers build the cutting die from the KLD geometry, and prepress places artwork, […]

Modern sheetfed offset printing press with 395nm LED-UV curing fresh glossy ink on a moving paper sheet
LED-UV curing emits a narrow 385, 395, or 405 nm band with no infrared or ozone, while mercury-arc curing emits broadband 200–450 nm radiation with emission peaks at 254, 313, and 365 nm. LED-UV needs matched acylphosphine oxide photoinitiators; mercury-arc cures a broader ink range but adds heat and ozone. […]
