In large format printing, it is crucial that incoming files comply with clear technological and quality-related requirements. Only in this way can a print company avoid not only additional (unpaid) work due to extra communication with the client and adjustments to the incoming files, but also prevent disappointments and quality complaints afterwards. For this purpose, Fespa Belgium developed specific guidelines in collaboration with expert Carl Van Rooy. These submission specifications will be presented for the first time during this session at Sign2Com.
