Default Discharge ink in Dtg printers

Hi im looking at getting a discharge dtg printer it uses dupont textile ink cmyk and a discharge ink. cant really find much info so wanted to make a post on it to get some info. If some can answer the following questions and provide additional info that would be great

Can you print photo quality images?

Is it true its a bad smell while print like as in really bad?

How dangerous are the chemicals in the discharge ink?

Can you print white on dark garments?

From what I know or have gathered -

-Photo quality should be possible
-You will need good ventilation and the garments will need a conveyor dryer for correct curing
-I guess it depends on the rip but if you're using discharge then the dye is being taken out, I'm only referring to a forthcoming system that won't have a need for pre-treat so I would imagine a white ink/discharge combo would be possible.
-Once the shirt is cured I wouldn't have thought it's be a problem but then I'm not an expert and discharge through DTG is a new process.

What country are you in?

For the curing process i will be using my hix heat press. I was told once cured by that should kill all the so called bad chemicals and would be safe for use but im no expert and that came from a dtg salesman lol. As for ventulation the printer will be in my spare room at home until it makes enough money to go in a shop. I will just have the window open when im printing hope the smell isnt that bad lol might get a extraction fan.
Im from Australia mate

Right, from what I've been told you can't do it with a heat press and an open window, it needs a conveyor dryer with an pipe taking the fumes away.

Like I said I'm not a 100% on this but what is the dtg printer that you're looking at?

Might be worth having a look in the Mimaki section on here for posts about the 604D.

Ok I would really look into and I'm sure they may have used a heat press and an open window but that doesn't mean it's safe.

If you're looking to China to get a printer then do your homework and do it again, I don't know your experience in the garment printing industry but there are fair amount of horror stories out there

Yea i been looking for a few months now i been in contact with them nearly every day too. I have re eived some samples from both the white ink and discharge the white ink printer was terrible pretty much faded and peeled off after one wash where the discharge was pretty much no difference. I seen both good and bad stories with this inparticular model im just a bit worried about using discharge ink as i dont know much about it and how safe it is. If i have to wash the garment before a client wears it im not going to bother as i do plastisol transfers and i see clients put the tops on pretty much staright after i press them on

If discharge was a vaiable option then Mimaki would not stop manufacuring their printers also major ink manufacturors would start making it.

Flaws with inkjet dicharge:

-its transparent so it wil only work on about 20 % of garments because only couple of brandsm styles and colors are dischargable.
- it has a very short life span.
- its really unhealthy I know that for example it will not pass EU certification for textile inks.
- you will never get colors as bright as when using propper white ink.

If you got samples with white ink taht washed off then the ink or the operator pretreating the shirt is at fault.

Kornit makes a discharge dtg, but it is 300k or so. You need some very tough stainless steel print heads in order to handle discharge ink.

Are you not mistaking it with reactive dye ink?
