Regards to pricing, of course it's laid out the pricing recommendations that one should be charging for based on the UK, however how would you price for the rest of the world to places like Germany France & Spain EU1 EU2 USA Canada AUS World. Does the price you set in pounds automatically convert and adjust for people who purchase your posters in the rest of the places that I added or would I have to do and adjust that myself? Thanks for the answer in advance!

I'm not too sure what the image quality should be when uploading it to PrintShrimp, should the poster that's being printed be 4k res? 8k res? 16k res? I do A series posters so from A4-A0 pls help lol
