Heidelberg Original GTK

Hello everybody,

I wanted to have a windmill for years but it was just not to be. Until this year when I suddenly have not one, but two. 2020 really is crazy.

One is in pretty good condition, was used in production, it’s a GTP, factory made for hot foil stamping.

But today I installed a second one, because I don’t fancy die cutting on my GTP. So I was after a GTS or just a regular GT. And I found a really cheap GT, it seems to run nice, was also used in production but it’s not a looker that’s for sure.

I was cleaning it just now and found GTK 67355 N stamped though, so not a regular GT. I searched some but I can’t find any information on line about it. So is it something else or they just started using 3 letter codes at some point (with GTS, GTP) and so a GT became a GTK?

Perhaps I can clarify.

GTK has an extra 3mm ground off the platen to facilitate a thicker plate and increase substrate range to 2mm. Same for the GTS but without inker. Tonnage (40T) is the same on all GT models. That’s the only difference between a GT and GTS & GTK

Just noticed the “N“ suffix. That indicates your press machined for German type height. 0.927“ and not 0.918“


Would you know by any chance what the deal is with this “reinforced” construction that GTS (and probably GTK also) has? It says in the manual that they reinforced it to withstand higher loads when die cutting with heavy dies. Shouldn’t that mean it has more tonnage as well?

it isn’t structurally different except possibly the special material shear-pin is stronger. All parts of GT to GTS the same.
