I decided to produce some physical posters, no bigger than A3 to see how they looked printed out. I decided to print them on gloss/satin paper, at 130 gsm to get the luxurious poster feel you get when you purchase a new poster.
I was able to print them full bleed on a roll, which saved me sizing them up to A2 in order to get the correct size, more money for other prints.. I had to measure 3mm from each edge, to get the required bleed, so the posters size to A3.
The final posters came out really nicely, I plan to put them up in various places and get some photographs of them, to see how they look in the environment to which they're intended.
