2.4.2 Mechanical specifications / restrictions
Definitions:
– Mechanical distances –
PH-CT: distance from print head (dot-line) to knife (cutting position)
PH-TB: distance from print head (dot-line) to tear bar (tear off edge)
PH-CA: distance from print head (dot-line) to center of printers RFID antenna
PH-DE: distance from print head (dot-line) to dispensing edge
– Mechanical restrictions –
MBF: maximum back-feed distance (without losing “grip” or ribbon wrinkling)
– Label/Inlay specific / depending distances –
LA:
inlay / label specific distance from top of label to leading edge of inlay antenna
ILG: label specific inter label gap (distance between two subsequent inlays)
OPA: RFID operating point measured from leading edge of antenna of inlay
OPL:
RFID operating point measured from leading edge of label (=> antenna offset)
