Frequently asked questions
Why use a triangle rather than a circle?
Because it is unmistakable. On a page carrying several stamps, the shape identifies the mark before the wording is read, which is the whole point in inspection and QC workflows.
How much text fits in a triangle?
Less than you would think, and it narrows toward the point. Two or three short lines is realistic. A triangle is for a code or a grade, not a paragraph.
Can I invert the triangle?
Yes. Both orientations are available, and which one means what is a matter of your own convention rather than a standard.
Is there a triangular stamp option too?
Triangle and triangular are the same shape. Use it as a triangular stamp maker or a triangular stamp generator, start from a triangular stamp template, adjust the triangular stamp design, build the triangular stamp online and export a triangular stamp png. A triangular seal is the same outline with formal wording on it.
Is the stamp maker free?
Designing is free and unlimited. Downloading the a triangle stamp is $1.50 for a single image, or $3.00 for every format at once. One payment either way, with no subscription attached.
Do I need to install an app?
None. Open the page and start typing. The a triangle stamp is drawn in the browser, so there is no download before the download.
Can I put the stamp on a PDF?
The a triangle stamp exports as a transparent PNG, which every PDF editor can place. The pack also includes an SVG, which stays sharp if the page is going to print at size.
Can each stamp carry its own number?
Save a triangle stamp to your library and it gets its own counter. Tick the numbering option at download and that file takes the next number in the sequence, incremented under a row lock, so two tabs or two devices cannot be handed the same one.
Can I design my own, or pick from templates?
Neither a static triangle stamp template nor a stock image: a triangle stamp generator you drive, and a triangle stamp maker in the sense that matters, which is that nothing is fixed. Choose a triangle stamp sample layout, rework the triangle stamp design, build the triangle stamp online and download when it looks right. The triangle stamp price is $1.50 for a single triangle stamp png or $3.00 for every format zipped.
Estamplab is a design tool. What a notarial or legal mark must carry is set by the authority that issued the commission or the appointment, and it differs sharply between jurisdictions, so check your own paperwork before relying on any layout here. This page describes common practice rather than giving legal advice. Only produce a mark you hold the authority to use: a stamp in the name of an office you do not hold is forgery.
