Screen cleaning is possibly the most unpopular job in a textile screen shop performed in possibly the most despised location — the “swamp”. For many years now dip tanks have been promoted as a means of making life easier and more efficient for swamp dwellers, but do dip tanks live up the hype?
It’s generally assumed that a shop should be “larger” before a dip tank can be justified. This is not necessarily true as dip tanks can be bought in a variety of sizes so that even small textile shops can consider one — which is most of the Canadian textile screen printing industry. The more important consideration is efficiency and labour time. The primary purpose of the tank is to soften up the stencil and ink at the same time so that while screen one is being rinsed, screen two is soaking and will be ready for rinsing when screen one is done. This obviously makes sense and is bound to make screen reclaiming more efficient. But there are other considerations.
Before ordering a tank, weigh the cost of it against the number of screens your shop recycles in, say, a year. Of course you may hate the screen-cleaning process so much that you’d pay a premium to make it easier — it’s your choice but at least be aware of the cost-benefit aspect. Then there are issues such whether the dip tank costs less in chemical consumption, whether the tank chemistry is safe to discharge into the sewer system, and how long the chemicals in the tank remain powerful enough to truly make it an effective dip-soak-and-rinse process (if the tank doesn’t consistently meet this standard then there’s not much point in having it).
Ask for contact information for dip tank users before buying one. Ask the tough questions. A dip tank could be a useful addition to the efficiency of your textile shop, but do your homework before deciding.
