Abstract (en)

Upon a substrate subsequent layers of elastic ink are jetted using an ink jet printing system. Each layer is immobilised by a immobilisation step before jetting the following layer. <??>A printing relief is gradually formed to obtain a flexographic printing plate allowing accurate control over the relief and slopes of the printing plates. <??>Use can be made of different inks or immobilisation step to obtain different layer characteristics. <??>Inks can be immobilised using UV curing. <??>The recorded relief of the layers can be measured and corrections can be applied using a feed-back loop. <??>A rejuvenation process for printing plates can be constructed using the described method. <??>An elastic base layer can be provided on the substrate to provide better plate characteristics. <IMAGE>
