Rear glasses are heated so they are subjected to a silver paste screen printing process as well as black printing during the screen-printing operation.

Glass tempering is, in principle, same for all types, but what is important here is how glass is bent prior to such a tempering thermal process. Rear glasses of vehicles have a more complex nature than that of other glasses, with tougher bending values. Thus, such glasses are shaped between male and female molds before they are subjected to a tempering process.

Electric connection components of the printing made for heating after such a tempering process are soldered.
