This study starts to find a way out, experiment and apply commercial UV coatings to the cap closures. The cap closures is made form coating and succeeding deformation process. It is coated with several printing layers, printing and over print varnish coating. Then it pressed in three steps of press called 'deep-drawing'. In this study, two kinds of coating was designed and accomplished in the base of the same manufacturing and environment conditions. Consequently, UV curable ink have adequate performance in this experiment (T-bending, Erichsen Test), but it were experienced several damages in this experiments (web-bending, impact test). They were not cured enough to endure the friction and a unique shape of serial cracks were appeared.
