How to GRIND BIG SQUEEGEE ?

Posted on Sat, 27 Nov 2004 at 11:06



Hello all,
I'm buying a Semi Auto press with breadthwise printing squeegee.
problem is which method of grinding is practical for a 65 inch squeegee.
Which is practically grinding flawlessly; Diamond head, big grind wheel, belt or what ?

Or is it practical at all to print f/color quality job on 1200 x 1600 mm press printing widthwise(printing with 1200 mm squeegee), due to the task of attaining such precision ultra level edge definition ?

Thanks for the time.

Hi,

I used to run a large Sias press with a short stroke action, the squeegee size was 2000mm, image size 1800mm (max).

Mostly we were printing promotional corflute - 4CP at 65DPI, using conventional inks.

If I got a nick in the squeegee I would have to sand with sanding block with a fine wet/dry - 2400GRIT from memory.
Once the squeegee got to "flogged out" we would replace.

Seemed a little expensive to me, though we did get a few prints out of it, maybe 4-6 weeks worth?

Thinking about it, I suppose the blade lasted so long because we would mask the substrate side of the screen with Mylar (mirror polyester S/A) right around the edges of the stock and lays/run on-offs, so as to provide the smoothest transition from bed to stock.

I hated the large machine, much better off with a long stroke for large format.

Good luck though eh.
