Prinect. The Pre-Press-PDF-Workflow of Heidelberger printing machines is the technical center of pre-press at Holzer Druck und Medien. Starting with editing of data up to creation of printing plates, this system can handle thousands of jobs per year. Whether there are automatically generated pre-set data for the printing machine or colour adjustments with uncoated paper, with Prinect the neccessary process-security and re-producability through PSO is ensured. Further points worth mentioning are: preflighting, optimisation of data and creation of multilingual orders. Large sized plotters and a colour binding proofer make the technology for pre-press complete.
