I’m trying to find a good website that i can print my works in poster form. I tried staples but the quality is no where near what i want. Any suggestion?
Why not just go to a local printer who can knock out some samples for you, show you paper types etc? Also, what is the quality problem you are having? Print shops don’t print posters in RGB so if it’s a colour fidelity issue you might want to view your poster in Photoshop in “Print” mode. That will let you see how the poster will look as a CMYK, which is what the print shop will output to paper. You can then adjust the colours in CMYK mode and get the best compromise possible before you send the file to the print shop.
