                  | Compared to other thermal processes, the UV process has 
                    4 merits below. 
 
 
                       
                        | ■Instant curing | ■Pollution-free and safety |   
                        | 
                             
                              | ●Time saving : |   
                              | The curing time only lasts 0.1~a 
                                few seconds |   
                              | ●Space saving : |   
                              | The process itself is compact |   
                              | ●Cost saving : |   
                              | The system can be design into 
                                a proper scale according to the disposal volume. |  | 
                             
                              | ●Improved working 
                                environment : |   
                              | In principle, the 
                                system is powered by electricity and no solvent 
                                are in use, so the system will not cause some 
                                problems of the air-pollution and odor emission. |   
                              | ●Simplified 
                                equipments : |   
                              | Solvent disposal 
                                devices and anti-pollution facilities are not 
                                needed. |  |   
                        | ■Low temperature curing | ■Improved quality |   
                        | 
                             
                              | ●Suitable for heat-sensitive 
                                materials : |   
                              | The materials can be chosen widely. |   
                              | ●Energy saving : |   
                              | Energy is just consumed in the 
                                necessary process at the necessary time. |  | 
                             
                              | ●Reinforced 
                                strength (high-intensity) |   
                              | ●Flawless and 
                                odorless : The finished work is perfect in uniformity and 
                                has no paints and any bad smell of ink with it.
 |   
                              | ●Metallic luster 
                                gives the product a feeling of quality. |   
                              | ●Solvent resistance, 
                                chemical resistance and pollution resistance are 
                                improved greatly. |  |  
 The realization of any each of processes: adhering, peeling, 
                    curing or drying relies on the chemical bonding of the organic 
                    compounds caused by UV irradiation.
 
 
  
 It is necessary to find proper processes for different products 
                    and materials. Being as an example, the different kinds of 
                    light sources used in UV curing process are listed below.
