Background technology
Currently on the market, offset printing online cold-foil is realized by transforming the two of offset press units, in first machine
In group, cold wave glue is transported to by the inking device on high-precision printing plate, is then shifted cold wave glue by way of printing
Onto stock；In the control system of second gold stamping paper tinsel of units' installation, by blanket cylinder and impression cylinder to pressure, scribble
The areas of cold wave glue in the aluminium coated reverse drawing of gold stamping paper tinsel to stock, will just complete the transfer of gold stamping paper tinsel, carry out thermoprint
Foil afterwards is just withdrawn by gold stamping paper tinsel control system.
But since the viscosity of cold wave glue is bigger, viscosity is stronger, and levelability is poor, after being transferred on stock, table
Face is in serrated face, completes the aluminium coated transfer product flatness of rear surface or poor, thus forms diffusing reflection, and offset printing is caused to be scalded
The product glossiness of gold is poor, and the phenomenon that numb occurs in surface, and the brightness difference with the small block effect on the spot of blanching is larger, therefore
Significantly limit the application range of offset printing cold wave.
