Anyone know if there is any harm in running an AzuraTS plate thru the processor (really, just a gummer) twice? Sometimes, when my gum is getting old and/or I haven't run a plate in a day or so, I get some gum gunk (spots, streaks) on the plate. It washes off on press with no problem, but I like to give the pressroom clean plates if possible. So, I just run it thru the gummer again.

I would never do this if this wasn't a "chem-free" plate, but I figure all it is doing is adding more gum and brushing away the gunk.

If there is a scrubber roller I'd be slightly concerned but if it truly is just a gum unit it should be fine. If you have one check the plate before and after with a plate densitometer and see if it changes the dot.

I've done it many times with the original Azura plates, and haven't seen anything bad creep up.

There is a scrubber, but the way the plate works is that the laser fuses the coating to the aluminum in the image area, and the scrubber removes everything that is unfused (non-image area). Haven't seen any problems yet.

Not one single problem. Nope. I do it too.

If they haven't already, Agfa should be coming out to replace a part on your C series processor. I guess one somewhere overheated, and now they're paranoid. Never had any issues with mine. Ever!

Just had our first TS issue... An exact reprint job from November 2009 came out lighter on press this go around. I had our guy go through our Screen Plate Rite and it all checked out within spec. I cleaned the processor to a pristine state, and changed chemistry to a new lot. Brought the plate back to a linear state and measure all values in 5% increments. It reads perfect.

Turned out we have three possible issues... when the Agfa guys came out to test the new American made plates, they might have changed laser intensity, which affects the baking of the plate. Still, the plate reads perfect when brought to a linear state, so it really can't be that.

We also changed press wash and ink manufacturers. It has to be an issue on press, so the TS still rocks!

It turned out to be a non-problem... Press issue.
