What temp to flatten color prints

[mark]

I have some ciba prints that have taken on the shape of their tube. Now that I have a mounting press I want to use it to flatten them. Problem is I do not have any clue as to what temp to use. I assume it is lower than BW prints.

I would not suggest using heat with Ciba. unless you are using the RC Version. the Melemex base should flatten well with out heat.
Do not mount Cibachromes with the melemex base they will not adhere over time.
