If it is Sepiax old ink hopefully they changed it because you had to print so slow on it that it never made since to even use it over 10 years ago when Sepiax was going to trade-shows with rebranded wit-color chinese printers. You had to print max pass and max heat and it was painful to watch and from my understanding. Hopefully it works out but they need to have orange, green and red option in my opinion.
The flatbed does not have white ink or greyscale heads, not sure who that will be for...Im not sure why a new printhead would attract anyone. Epson has the best image quality of any printer in its class right now. The ink smells because 4 years ago they decide to try to follow HP with quicker off gassing times. Now you can laminate in the same day with the GS3 inks. Yes they smell because of that. Their inks are as scratch resistant as Roland, Mutoh and Mimaki. HP needed to address scratching with their gen 1 latex printers...again...EPSON should just be EPSON and stop trying to be HP. Your market has always been image quality...stay there.
The flatbed will flop. Too little too late. rant over
