- That's strange news!
-
- However, the DIN standard says that it is compatible with the ISO standard,
- only the tolerances allowed by DIN are smaller than those allowed by ISO,
- which isn't an incompatibility.
-
- How have the JIS people defined the B series? In ISO and DIN, it is
- just the geometric mean between two A series sizes (geometric mean of
- a and b is sqrt(a*b)).
-
- Still confused ...
-
- Perhaps you mean the following: DIN/ISO define paper end formats. You write
- 'printers ... use'. Do you mean the size of the paper delivered to the printer
- before it is sent to the offset printing machine and cut to e.g. B4? Ok,
- that is not the 'paper end format' that is of interest for the common user.
