The present invention discloses an accurate digital ink supply method for a printing press. The present invention adopts metering-type ink delivery units to replace the ink keys of the traditional printing press, and the metering-type ink delivery units directly deliver the ink to the corresponding ink zones on the metering basis of either volume or mass, realizing the quantitative supply of ink to each one of the ink zones. The present invention can perform accurate adjustment in real time, is high in automation and digitalization degree and large in adjustable range, realizes one-way ink delivery and avoids ink return.

Digital ink-supplying method for printing press

The present invention discloses a digital ink duct for a printing press, comprising an ink tank for storing ink, a main ink pipe that communicates with the ink tank, at least one metering-type ink delivery device, ink delivery pipes, a controller and a signal acquisition device. In the present invention, high-accuracy, metering-type ink delivery devices are arranged in a queue to form a digital ink duct which replaces the traditional ink duct and supplies ink for the ink zones. The present invention can perform accurate adjustment in real time, is high in automation and digitalization degree, and can realize one-way ink delivery and avoid ink return.

Digital ink duct for a press, digital ink supply system and application method thereof

A method of preparing Cu(In,Ga)SSeCu(In,Ga) (S,Se)(CIGSS) absorber layers uses coated semiconductor nanoparticle and nanowire networks. The nanoparticles and nanowires containing one or more elements from group IB and/or IIIA and/or VIA are prepared from metal salts such as metal chloride and acetate at room temperature without inert gas protection. A uniform and non-aggregation CIGS precursor layer is fabricated with the formation of nanoparticle and nanowire networks utilizing ultrasonic spaying technique. High quality CIGSS film is obtained by cleaning the residue salts and carbon agents at an increased temperature and selenizing the pretreated precursor layer.
