I have seen a iCTP, I don't remember the name exactly, from glunzensen and look like the Epson stylus pro (we have 2 epson 9400). I think it isn't good solution for print. Because:
1. Too slow output in hight resolution.
2. Only for short run length.
3. The image area isn't stable.
But: the iCTP machine is cheaper than CTP machine, the plate don't need chemistry to deverlop.
