Abstract
This invention relates to an ink jet system (10) and to a corresponding method of use suitable for rendering the printing characteristics homogeneous upon changes in working conditions, such as the type of printing medium, inks and ambient conditions. The object is attained through optical means (24) suitable for detecting the quantity of light reflected by appropriate patterns and a control unit (21) suitable for processing the data corresponding to the quantity of light reflected in order to identify the real dimensions of the ink droplets (dot size) on the printing medium and for transmitting them to the print management programs or print drivers (67b). The system (10) and method guarantee total independence from the working conditions, with the result that the images printed will be uniform no matter what the conditions.
