Water Based Ink is the commonly use ink by Pilipino printers today.
We have tried it before but given up on it because it was not compatible with our production area and that's what I'm gonna share with this post.
The most common advantage of WB ink is the curing. You can just hang it there and it is done or you can use blower for faster drying. Easy, right? But for big orders like 100+, it is very hard because of the clogging of ink. Easy to dry means ink dry faster when your production area is hot or in an open area where air always blow. Imagine printing 10 shirts per round (10 platens) and your screen also clogs every round. There is also a high risk of your design broken from always unclogging it. There are many techniques out there to avoid this kind of issue, example printing at night or always flood your ink on screen etc. Google is your friend.
We gave up WB ink because of this very issue. Also, the maintenance of your screens are a big head ache. You need to wash it every time youprint. Imagine printing 100+ shirts and you are very tired but you need to clean your screen first before sitting there and calculating your profit. You really need enough man power to get the job well and easy for your workers.
WB ink is cheaper than Plastisol Ink and the production cost is also low but you need the right formula for production to avoid its fatal issue of clogging.
