a4 poster for a3 print?

[squidmonk3j]

i've made this poster, orginally intended for a4 print. now, will it look a mess if boosted onto an a3 poster? 300 dpi.

i'm really unsure about this one, although i realize there's gonna be some heavy duty "stretching" involved, i'm kinda hoping it won't look like an amiga screenshot.

if so, is there any way to fix ( improve this)

anybody?

Are you printing this at home or at a repro house?

Ive had A3 prints done from A4 images at 300dpi and they looked fine. I did get it done at fedex kinkos mind you.

Ring around a few print places and see what they say.

There's always the various sharpen filters, in moderation they help blurry edges. 200% should print decent with a few tweaks if it's very clear originally.
Depending on the image, you might wanna paint over some important bits like eyes or whatever to give the impression it was painted that size to anyone who looks close :) A few flawless edges here and there, you know?
