Hello,

So I'm trying to do essentially the same thing. I want to make a decal for a welder faceplate and the only images I can find are either blurry already (probably from being resized) or keystoned or photographed.

This image needs is straight but blurry. It also needs to be scaled up 110% approximately to match the dimensions of the welder. What's the best way to sharpen this? I'm fairly resigned to retyping the text and placing it. Also I'd like to make it only black and white and elminate the grayscale in between. Here are some other images I've found that are clearer but have other issues preventing me from making a decal from them.

I've got adobe illustrator but I'm a newbie to graphic design, I primarily do design work from an engineering side (i.e. technical 3D modeling for manufacturing) not an artistic side.
