need some help guys! I'm taking drawings from archicad into photoshop so i can render them, I've placed the plan onto a layout sheet saved it as pdf with the hairline box ticked under document options. then I'm opening it in photoshop the anti -aliased box is un-ticked and resolution at 600 pixels. the document is an A1 size and looks fine except when i zoom in the lines are pixelated : / anyone know how to fix this? thanks in advance
