1) create image in Midjourney, click creative (upscale) and download as PNG
2) use Upscayl and upscayl x4. (I’m finding that the file size after Upscayl is between 80-106mb depending on how complex the design is). This won’t go into canva unless the file size is reduced.
3) Import into Photoshop A0 template (841 x 1189mm) set to CMYK, set resolution to 300 pixels/inch. Is this correct? When I go to export it, which settings do I need to make the file size significantly smaller as a JPEG? I’ve read comments on here that it needs to be a certain size for Printshrimp (and to be imported into Canva as the limit is 25-50mb?)
