Hi, Lilyo, thank you for responding so fast.
Yeah, i need to make a piece of 11''x17''; when i do non-pixelate stuff, i usually make it at 300dpi.
I've tried to have a 72dpi resolution and then expanding the art into a 300dpi document. I don't know if it's the anti-alias or what, but the pixels get pixelated (?).
I need the print to be, as you say, crispiest as it can.
