1. A method of controlling a drying apparatus for a printing press, in which said drying apparatus is equipped with a light
source to dry a drying matter of a print by irradiating light of said light source on said print, comprising:
presetting a correlation between information relating to the time for which said light source is lit and information relating
to the amount of light of said light source;
detecting information relating to the elapsed time for which the light source is lit during said light source is lit; and
controlling light of the light source to a constant amount, regardless of the elapsed time for which the light source is lit,
based on information relating to a reference amount of light, said information relating to the reference amount being obtained
from the preset correlation between said information relating to the time for which the light source is lit and said information
relating to the amount of light with reference to said information relating to the elapsed time at the time of the detection.
