What thresholding does to an impression
One cut-off, two outcomes
Every pixel is compared against the threshold. Darker becomes black, lighter becomes nothing. No intermediate value survives, which is precisely what a die cutter or a single-ink press requires.
Making a die from an impression
If you are having a new rubber stamp cut from an existing impression, the manufacturer needs unambiguous artwork. Handing them a greyscale scan means someone at the factory picks the cut-off, and they will pick it without knowing which parts of your seal matter.
Where to set it
The default of 150 sits lower than the signature equivalent because a seal has large solid areas rather than thin strokes, so there is more ink to keep and less risk of losing it. Raise it if fine rim text is dropping out, lower it if paper texture is coming through.
What you give up
Thresholding removes the soft anti-aliased pixels that make an impression look real. The result has hard edges and looks manufactured, which is right for a die and wrong for a document. Use Change Stamp Colour when the seal will be viewed rather than cut.
It also rescues a poor scan
Paper discolouration, coffee marks and scanner noise all sit above the cut-off and vanish entirely, leaving just the ink. It is often the fastest way to clean up an old impression.
How to create a black and white stamp
Upload the stamp
Drop in the scan. Higher resolution gives a smoother edge once thresholded.
Set the threshold
Drag until the whole seal is present but the paper texture has gone. Higher keeps more ink; lower keeps less.

Where a two-tone seal is required
Cutting a new die
Give the manufacturer artwork with an unambiguous boundary rather than a greyscale guess.
Laser engraving
Supply the two-tone form an engraver needs to know where to burn.
Single-ink printing
Prepare a seal for a press that lays down one colour with no halftone.
Cleaning an old scan
Erase paper discolouration and age marks in a single pass.

What people use it for
The jobs the editor was built around — and what it does differently on each one.
Colourways you can revisit
Every edit is a layer, not a bake. When the brand shifts, reopen the file and change the colour rather than rebuilding the variant from the original.
Cutouts with awkward edges
AI background removal that keeps hair, foliage and soft shadows instead of stamping a hard outline around them. The output is a transparent PNG, ready to place.
No export, edit, re-import loop
The Framer plugin runs on the canvas you are already working in, so a recolour or a cutout does not mean a round trip through a second application.
Ten options in the time one used to take
Recolour once and step through the alternatives, so a client review can look at the whole range instead of the one version there was time to make.
Brand colours matched exactly
Pick a colour straight off an existing asset and get the hex, rather than eyeballing it against a screenshot and hoping it is close enough.
Free to preview, priced per export
Previewing is unlimited and costs nothing. A credit is spent only when you download a full-resolution file, so exploring an idea is never the expensive part.
