When you first receive your new stamp we recommend trying it out on scrap paper a few times to make sure the surface is completely covered in ink. Also so you can get a feel for the amount of pressure required.
We recommend you stamp from above to get an even finish. As you lift the stamp always loosen paper or card at the same time to avoid smudging.
The dye is cut around the artwork so may not have straight edges. Also, the block may be bigger than the artwork.
