Abstract: Consider the current development stage of the vehicle, it has become the consensus of the vehicle factory to actively carry out the design innovation. As one of the design innovation schemes, two-tone has been adopted by the vehicle factory. However, the growing demand for two-tone has brought many problems to the vehicle manufacturing to be solved. This paper briefly introduces two kinds of widely used two-tone technology which named color film change and conventional two-tone technology, and then introduces one new technology which named low overspray paint print technology. In addition to a brief introduction of the development status of low overspray paint printing technology, it also thinks about the potential impact of this technology on the development of vehicle painting technology in the future. The results show that there is still room for improvement in the weatherability of film materials, while conventional colorization has great pain points in manufacturability and economy, while low-overspray paint printing technology can provide both manufacturability and weatherability.
