A little update to the process and what's been working for me and pretty much become the default heat/temp/time for me.
- Pre-heat Groovy pouch with the vinyl flat inside for 45 minutes. (Groovy Pouch set to Medium)
- Standard to medium weight album cook time - 90 minutes | Heavy weight albums cook time - 105 minutes
- Let pouch with VF/LP inside cool to room temperature (2-3 hours)
I think the cooling process is just as important as not setting the temp too high, the vinyl will want to go back to it's original state if still flexible enough to do so, so leaving it in the press until absolutely cool is a big step.
It's been great to be able to test and adjust the theory over time and thank you to those who trust me with their LPs
