Scaling up the printing technology
As PRINTODECO Project moves ahead, new challenges appear. One of the examples is the up scaling the printing technologies. Most of the developments of PRINTODECO have been made using slow printing technologies. Those technologies allow technical development, but they do not support industrial scale exploitation.
Considering that, SEISTAG proposed testing high volume printing technologies during the summer of 2018. For that reason, the companies developed new trials using singlepass printers instead of multipass. TORCULO provided the tools needed to test both technologies: HP INDIGO for singlepass experiments (showed above) and large format plotters for singlepass (used up to the moment on PRINTODECO Project).
Singlepass technology is based on paper passing across a line of print heads, which is wide enough to cover the whole width of the paper. Meanwhile, multipass technology relies on a movable print head travelling across the paper. The first system represents a big investment, but it reaches very high productivity and therefore low productive costs. The second technology is much cheaper in terms of investment, but represents higher costs per square meter and could not supply the amounts of printed-paper that might be demanded by the melamine board industry.
