Everything Jonathan is saying is right on...here is what I did and am currently doing. First of all, I screen print at home in our spare bedroom with a table top 4 color/1 station unit. I started out with waterbased inks and a heat gun...worked great for a while but what I found was I wanted to do much more, turn it into a business, so I wanted more stock ink colors and not having to use a bunch of additives as you do for some waterbased inks. So I made the switch to plastisol inks. But with that I needed either a flash dryer or conveyor dryer to cure the ink...I did not have enough room for a conveyor so I got a good flash dryer...it is not ideal to use a flash dryer to fully cure shirts but to get started until I can have proper space it definitely does the job! I will use my heat gun to "flash" cure if I am doing multiple colors since my flash dryer is away from the press to cure the shirts. I am just making due with what I have until I can have enough money built up to either rent a small space or build something in the back yard. :)

Regarding waterbased vs plastisol, it really comes down to what you can do curing wise and personal preference. If you can get something for proper curing I say go for plastisol...waterbased is nice because it cleans up easy but it does tend to dry fast. However, I had great success with Ryonet's Enviroline which are Matsui waterbased inks...they did not dry super fast when sitting for a while...still will dry just not really quick as others do and they always gave a beautiful print. I cannot say anything bad about them just decided that plastisol was the way I needed to go.

Hope this helps.
Thanks for that Leadfoot, Here in the UK things drying quickly isn't ever a problem :D I dont have the cash/space for a flash unit, I do have a hairdryer and a heat press though.

And I don’t have the time right now to set up a multi-color on a white under base just to do a video. But when I get a chance in the future I’ll do it. But for now we may only test a 1 color cure with the heat press.

As far as the discharge thing goes you can do that but the discharge has to be cured first otherwise it will affect the color of whatever you print on top when you cure it.


:D
Looking forward to seeing that video buddy.
As for discharge ink, does it require a static temp to cure or do different colours/makes need different temps?

Yeah I think I'll do the heat press curing video next week perhaps. Only with a 1 color print though but it should be able to tell us if it is even possible to attempt anything further.

Discharge inks should all cure at the same temp as long as they are all of the same brand.


Stay tuned.....
