Spare parts are supplied as original and as compatible. Which part belongs in which production is not guessed without the machine identity and the notes from site.
Anilox, sleeve, magnetic cylinder, knife and UV components are the items asked for most often. They look like consumables; they decide print quality as much as the press does.
A part can be requested together with installation or service. An order on its own is also taken; the fit is still checked from the same source.
