Printing Alu Panel iPhone covers

[Andrew]

If you have slight mottling then this is usually a clear indication of too much heat having been applied. Hard to be 100% without a photo of the problem but that would be the first area to explore. Reduce time and/or temp a bit. We use 195c for 60s with an epson. Less heat required for a Ricoh.

I can never remember a problem with printing due to damp paper and we have a couple of cold warehouses to work out of.

You should never have the need to 'dry' your paper prior to printing, if that's the case you have a serious moisture issue!

I've been doing more and more of these covers and for me at least I find if I pre-warm the metal first and then print upside down as mentioned, I just let the platen sit on the metal so minimum pressure. I put a silicon sheet under the metal and a sheet over the top to protect the upper platen.

I print 50 secs 195c.

Different batches of metals (even from the same supplier) will give different results. There are too many dodgy batches that come through which can further complicate working out problems. Sometimes it is just the metal that gives poor results.
