please help - setting up small screen printing station

Posted on Wed, 8 Jun 2005 at 18:24



Hello fellows,

I work for a vinyl sign co and after reading an article in Sign Business Magazine we are trying to set-up our own small screen-printing station.

We will be printing exclusively 18"x24" one color coros, text only (well, maybe simple outlined logos)

Our Ideas for that is to buy few frames with screens 155 white mesh, like 24"x36", make our own screens with UlanoCut Amba cut film, use 60 durometer squige. We are thinking of using Nazdar inks 9700 series with 5% added NB 70 Catalyst.

My questions are will the UlanoCut Amba film work well for this printing? Will it give clean, sharp edges of the print-outs?

And most importantly is there any odor and harm less inks we can use inside of the office? We don’t really need the signs to last more than 4-6 months.

Thank a lot for any possible input,
regards,
Stan

Stan, here are a few comments.

Screens...get 230-250 if you are printing coro (or any other bold graphics) - You will get too much ink through the coarser mesh, and you edges will look ratty.

Your screens might be a tad small (I'm assuming those are inside dimensions) especially if you try to print a bleed. Easier to print with a bit bigger screen (4 more inches all around)

The knife cut film on your vinyl cutter will work. (apply with water, use it with solvent based inks only)You have to get your technique down for applying it.

Get a 70 duro squeegee, 60 will fold right over.

If you get into it, you might want to consider cutting rubylith on you vinly cutter (or you can just cut black vinyl and adhere to clear plastic sheet) as positives and expose your screens using direct emulsion - then you just pull your old film and burn a new screen.

Re the stinky ink....coro needs an ink that will bond well. Most waterbased inks I've tried won't stick on coro well. with solvent based comes the smell. You might want to do this in a separate area than the office - in a garage or out back. they have specific coro inks, if that's all you are going to run. I use Dry Film by ND graphics, great multipurpose works on vinyl, styrene, coro, acrylic, paper, card - but only available in Canada I think. You can go whole hog and go UV, less stink but it's going to cost you $10,000 to get a dryer!

build a vacuum table, makes it ssooooooo much easier. You can pile stuff on it when it is not in use.

Good luck!

ps...print across the flues if you can, does a better job.

Andy is right, you might also go on the NazDar site they have a tech help section also which might help you since you are trying their inks. The knife cut films work well if they are applied properly and you can get them on without the bubbles and air pockets. Might want to get some retarder with inks to help with the drying in if you have that problem.

This is not that hard and you most likely will figure it out after a couple of trys.

Hello guys,
thanks for all the help!

I'm thinking of using water based inks with "adhesion promoter" on a 250 mesh screen. Do you think it is going to work for short term signage (up to 6 mnths on coro)

Thank You all again!
