US Patent 10241401 Method of making a flexographic printing plate

A method of producing a flexographic printing plate using a continuous liquid interphase is provided herein. This method allows for significantly reduced production times and fewer preparation steps compared to standard non-continuous techniques and results in less waste than typical methods for preparing flexographic printing plates. The printing plate provided by using continuous liquid interphase production results in a printing plate with desirable elastomeric elongation, desirable hardness, plate thickness in the range of 0.030 inches to 0.250 inches, and comprises printing dots with desirable characteristics.
