Mr. Nishad is our regular customer, he totally bought more than 10 sets of machines from our company since the year of 2015 we met, including large format UV printing machines, eco-solvent printing machines, and small size UV printer. In the past, EPSON DX5 print-heads eco-solvent printer was very popular, but from the experience, the new generation XP600 print-head is better. It has the same print resolution as DX5, but the cost for a new head is much lower than DX5, very cost-effective, only one disadvantage is lifetime shorter than DX5. At the present stage, we are keeping improving our technology and machines, hope to provide more and more quality machines and satisfied service to our customers.
