I use 160gsm with 50mic laminating pouches.
It comes out to 0.30 mm which is better imo than 180gsm which comes out to 0.33mm for me. But that’s up to you guys to decide!
I use the ET 8500
Finally satisfied!
Material:
160gsm double sided photo paper
50 mic laminating pouches
-> comes down to 0.3mm which is better then 0.3mm in my opinion with 180gsm paper!
First print it (I‘m using the ET8500), let it gas out for about 30 minutes to an hour. Preheat your laminator and make sure it’s good to go and then cut with the Die Cutter or the Silhouette for easy and high quality proxies!
