Matsui discharge is not best. Only cci, rutland and magna ok. Matsui introduce new thiourea based discharge but still not good.
Noortrd,
Not sure where you are located, but I am in the USA and we are not allowed to sell a Thiourea based discharge due to the Magna patent.
Which other discharges of ours have you tried? We have more than 5 different ones. What are you looking for in a good discharge ink? Do you need Eco friendly?
We want to help you find the best solution. I am sure the other companies have a great product, but most interested on what you do not like about ours. Feedback is very important to us (Bad or Good).
