An ink supply system comprising
- an ink supply means which supplies ink in an ink container to an ink fountain where the ink is temporarily stored between the ink is discharged from an ink container and the ink is supplied to the inner peripheral surface of a printing drum,
- an ink amount detecting means which outputs an ink supply starting signal when the amount of ink in the ink fountain supplied by the ink supply means becomes smaller than a predetermined first threshold value and an ink supply terminating signal when the amount of ink in the ink fountain becomes not smaller than a predetermined second threshold value,
- a time measuring means which measures the elapsing time from the time the ink supply starting signal is output from the ink amount detecting means,
- an empty ink container recognizing means which recognizes that the ink container is exhausted when the elapsing time measured by the time measuring means becomes longer than a predetermined inkless time before the ink supply terminating signal is output, and
- an ink supply control means which starts the ink supply means supplying the ink in response to the ink supply starting signal and stops the ink supply means from supplying the ink in response to the ink supply terminating signal,
- wherein the improvement comprises that the empty ink container recognizing means reads out a parameter from a storage means which is provided on the ink container to store a parameter representing an inkless time corresponding to the kind of the ink in the ink container, and sets the inkless time on the basis of the parameter.
An ink container which is used for carrying out an ink supply method where supply of ink from an ink container to an ink fountain where the ink is temporarily stored between the ink is discharged from an ink container and the ink is supplied to the inner peripheral surface of a printing drum is started when the amount of ink in the ink fountain becomes smaller than a first threshold value and is terminated when the amount of ink in the ink fountain becomes not smaller than a second threshold value after the supply of ink is started, the elapsing time from the start of the supply of ink is measured, it is recognized that the ink container is exhausted when the measured elapsing time from the start of the supply of ink becomes longer than a predetermined inkless time before the amount of ink in the ink fountain becomes not smaller than the second threshold value after the supply of ink is started, a parameter is read out from a storage means which is provided on the ink container to store a parameter representing an inkless time corresponding to the kind of the ink in the ink container, and the inkless time is set on the basis of the parameter, comprising a storage means which stores a parameter representing an inkless time corresponding to the kind of the ink therein.
