Aluminium water bottle issues - temperatures?

[carolm1a]

Hi all

Does anyone use an st3042 or oven to do the aluminium water bottles? I was told the temp and time should be 200c for 6 minutes but the colours are coming out really dull and not as I would expect. I'm using the white aluminium ones.

Thanks all xx

6 minutes seem short to me. I use a halogen oven and it takes 12 minutes.

not sure a vacuum oven would cut down the timings that much. I always thought the vacuum component was to apply pressure to the transfer rather than shorten cook time.
