Aquatherm®SP is a thermal negative plate that is both environmentally and budget friendly. Fast laser imaging speed allows for increased press productivity, while off-press development with water lowers chemical costs and reduces harm to the environment. After development with water, Aquatherm®SP plates can be post-exposed with UV exposure units normally used to expose PS plates or can be post-baked for over 1 million impressions with normal and UV inks. AquaTherm®SP plate is suitable for both sheetfed and web offset presses.
Plate Non-ablative thermal negative plate with wide operating latitude, optional post UV exposure or post baking for extremely long runs with normal and UV inks.
