Default Coroplast Printing Help

I own a sign production company in PA. We originally started off screen printing garments and moved on to signs, large format printing and CNC routing.

I have a 6 station 6 color Workhorse manual press. It has only ever been used for clothing. I now have a huge local demand for Coroplast signs and I would like to use the press for screen printing coro and aluminum. It appears that the state of the national economy has people looking for cheaper ways to advertise and many are turning to yard signs.

Anyway, I am looking for advice on using my press for coroplast. I need advice or suggestions on mesh counts, best inks to use (air dry) and do I need to invest in a vacuum hold down or is there another way to do it.

Thanks!

Hi:
I have print shop in Toronto Canada. Signs 101 Canada. We make coroplast Signs. Ink we use is Coroplast ink. Does not fade out in years. This is Air dry ink. I takes about 20 mins in room temprature to dry up completely. you can just use one head to make one color signs. But before you run 2nd color bords must be completely dry. Encourage your customers to go for one color. They really don't need more then one color unless they want to spend. you will get more customer if you keep your price. It is always the price which birng customer back.
Popular Size of coroplast signs is 16x12 inches, 16x20" and 24x16 inches. There will be no waste this way in 48x96 sheet.
You can make cheap drying racks If you don't have conveyor dryer.
Mesh count 195 or 230 for fine work. 195 will be good.

My shop also does coro on our press and we use Nazdar inks, 255 mesh screens because the ink is thinnner. If you use any lower then that it will lay to much ink. Also we use a conveyor dryer even though the ink is air dry. We put the dryer speed all the way up and just use it to heat it up speeding the dry time to 1-3 minutes.

I do agree anything more then one color can be a pain but you can do it.

Build a jig - a couple of pieces of beading on a board and register to that.
