Whenever I try to make a border-less print without an easel, the paper has a tendency to buckle in the middle. Although it's miniscule, the slight variation in the height is enough to throw the focus off.
Any tips on how to get a good flat image without having to get a sans-border easel?
You don’t mention what paper you use, but if gloss, take all the paper out the box and repack it face to face and back to back. This will make it flat when aligned on your baseboard.
