I am currently based in the UK and am broadening my current t-shirt business into posters and flat substrates. I am having real difficulty in finding some sort of decent pre-mixed poster ink that can be bought in litres as opposed to Gallons.
There is System 3 Acrylic which is readily available and when mixed with a binder works well, however it's not what i would imagine to be a high quality print. I haven't tested this yet, but a few of the painters that work near me suggest System 3 is a terrible acrylic paint, not sure how well that translates to screen printing, but i need to have a decent level of quality.
I have tried Permaprint which is relatively good.... except it dries in the screen after 2 pulls even WITH back flooding on a 71 mesh... This stuff allegedly goes through 120 meshes as standard... somehow i don't think so.
I have looked into TW Inks, and they seem like the best bet, however they are only sold unmixed in gallons with base and pigment needing mixing, pigment is £80 per gallon, base is £60, which is ridiculous.
I'm tempted to order Nazdar or Speedball from America and have it shipped over, because i can't see any other option currently in getting a decent poster ink. Nazdar has an office in the UK but the ONLY ink it doesn't stock readily is the 2700 Series Waterbased poster ink...
Does anyone have any suggestions here?
Thanks in advance.
