Entrust (Datacard) 532000-053 Graphics Monochrome Ribbon Kit, Black HQ - 1500 Prints
The Entrust 532000-053 is the Graphics Monochrome Ribbon Kit, Black HQ. HQ is Entrust's abbreviation for high quality, and Entrust also grades this ribbon as Premium / High Opacity, which is what separates it from the Standard / Food Safe black. It has a single black resin panel, and one roll yields 1,500 prints. It fits the Datacard SP35 Plus, SP55, SP55 Plus, SP75 and SP75 Plus card printers, along with the SD260 and SD360. A cleaning card and cleaning sleeve are included with the ribbon.
Entrust's legacy part number for this ribbon is Datacard 552954-601, and both part numbers are the same Black HQ supply. If you need the Standard / Food Safe black instead, that is a different part number. Current supplies require an SP-series printer whose firmware has been updated, so this 532000-053 kit is the one for an SP-series printer that has had that update.
