Poster design advice

...

Reason number 2 who I print in black and white only.

Time and date would be hard to disable, but it wouldn't be too hard to open a printer and fuck up the GPS module.

Unless of course, they won't print without a GPS fix.

So what would you recommend? Is it the Elmer's glue and vinegar mix 2:1 that i saw in another thread?

No. That is for stickers. For this, simply mix Tackey glue (or some variant) and water. Apply to the surface you want to paste your poster on. Then place your poster. Finally paint over the entire poster. Waterproof and difficult to remove.
