difference between speedmaster cd102 and SM102?
can someone please explain the difference between a speedmaster SM102 and a speedmaster CD102?
having a debate with a co-worker about this. neither of us know.
Hi Albert, never run either so not sure of the specific deifferences but D stands for carton Device (i'd assume it would have extra sheet guides all over the press in addition to other things)
CDs are meant for heavy board stock ie:24pt and such
Not that the other machine won't handle it but with the CD there is minimal if any chance of marking or slap do to paper thickness with heavy ink coverage.
I'm sure someone will explain it better but those are the words I got when the Heidelberg techs were installing our sm74.
If it were my buck on the line I would have went with the CD.

The CD102 has double size impression cylinder and triple size transfer cylinder which gives the sheet a smoother path through the press. The SM102 has a larger number of smaller cylinders to pass the sheet meaning more bend to the sheet and more gripper changes.
CD can run thicker stock with far fewer marking problems.
You can download the spec sheets for each machine from Heidelberg's website which show a diagram of the cylinder configurations.
I don't run a CD any more but I wish I did!
ok i thought that the CD stood for carton device (ie: more sheet guiding devices)
thanks for clearing that up.
do they process thin stocks as well as they do with the heavier stuff?
for example, can you run 18pt c2s and then switch to 50lb uncoated right after and have it run just as well?
obviously the 102 stands for 102cm (or 40 inches)
I've attached some cross section of both presses. This will answer your question.
the 10 color is a Sm, the 6 color is a CD
thanks for the graphics.
by the looks of it, the CD is obviously better.
the only advantage of the sm over the cd is that the sm can be equipped with a perfector, while the cd cannot (officialy)
where can we download the operating manuals for both machines?
The CD is by far the better configuration, much quicker to wash up as there are no transfer cylinders to clean, or to get dented by a folded sheet like the transfer jackets on the SM, no marking problems on the sheet's journey through the press, and if you want to run thin stock, you can run with the shells in.
Right now I am running a 105XL which is a great press, with lots on new design features over the old CD's.
