What is the best plate thickness for 4×5

[CrooksPhoto]

Hello all,

I have been doing quite a bit of research online (books haven’t arrived yet) and can’t seem to get a good bead on copper plate thickness. I have found everything from .02 – .05 recommended. Obviously at the .02 side of things I have to worry about bending. With .05 I don’t as much but get into having issues with my standard 4×5 film holder, maybe?. SO I ask the masses what is the best thickness and is any film holder modification required?

Thanks in advance.

Hi Matt,

I tried 0.7 copper?0.7 brass?0.8brass? and 1.0 copper.

I got some plates from different dagpists all over the world when I was in trouble with electroplating.I found some use 0.5mm,some 1.27,some 1.5mm.

0.5mm copper is easy to be curved when you polish base cooper before eletroplating.My experiment is 1.0-1.5mm cooper is the best unless you can do the same nice word as Mike Robinson does.Of couse,brass is good to use too.

Hope this can help you.

best,

Li
