Yes I’ve opened vectors in Photoshop, but I don’t know what Photoshop does with them after that.
Right, it can open them, but can’t save a “true” vector file. If your print shop absolutely REQUIRES a vector file in order to print, then you’ll need to use Illustrator/Inkscape (or find a different print shop 🙂 ) So far in my printing experience, I’ve never needed to save a vector file; they were always happy with TIFF or PDF.
When you say “bleed”, are you talking about the couple inches around the edge of the banner? I don’t have to worry about a shape bleeding with text, do I?
Yes, I’m referring to the margins around the edge. https://www.carlisleprinting.com/content/article/bleeds-page-bleeds
