I've created a wordcloud image on an online programme. It can be downloaded as PNG 32MP HQ or JPEG 32MP HQ. I'd like to download it as high quality as possible, and print in colour onto high quality paper, and frame it. And I don't have a clue about printing, resolution, etc.
So, my questions:
1. Is either PNG or JPEG better? Is 32MP good resolution for a sharp image?
2. Will either of those downloads allow me to stretch the image into A3 size, without losing resolution?
3. For the best image and quality: I can use a fairly high quality colour printer and I could get good quality paper maybe in an art shop, or would I be better off going to a printing place with the image on a USB? If the latter, any recommendations for where in Dublin I'd go? I'd hope to print onto white textured paper, like what you'd see for good quality prints or framed pictures.
