Smooth Pen Brushes That Feel Like Real Ink

A drawn signature should look like yours, not like a line from a paint program. SignPe’s pen responds to how you write, so your signature comes out the way it does on paper.

Smooth pen brushes that feel like ink at a glance

Speed-sensitive line

Slow strokes come out thicker, quick flicks thinner — just like a pen on paper.

Tapered stroke ends

Lines fade to a point where you lift off, and a tap leaves a dot.

Built-in smoothing

Shaky fingertips and trackpad jitter are smoothed into clean curves.

Black, blue or red

Choose your ink colour, and use Clear to start again whenever you like.

Why a drawn signature should look like ink

Most people have signed their name the same way for years. When a signature pad draws it as a flat, even-width line, it looks wrong — stiff and mechanical, nothing like the signature on your passport or chequebook. That makes signers hesitate, and it makes the finished document feel less like something you actually signed.

SignPe’s pen brush is designed to behave like ink. The line changes with the way you move, so the result keeps the character of your real signature: heavier where you press on, lighter where you sweep through.

How the pen works

  • Speed-sensitive thickness. Slower strokes draw a thicker line; faster strokes draw a thinner one. Linger on the first letter and it comes out bold; flick the final underline and it trails off light.
  • Tapered stroke ends. Each stroke narrows where it ends, the way ink thins as a nib leaves the paper.
  • Dots that are dots. A single tap leaves a round dot — so the dot over an i or a full stop looks right.
  • Smoothing. Small wobbles from your finger, mouse or trackpad are smoothed out, so curves stay curved and loops stay round.
  • Three ink colours. Draw in black, blue or red.
  • Clear. Not happy with it? Tap Clear and draw again. There is no limit on attempts.

The same pen is there wherever you draw: in the Draw tab of the signature window on the web app, and in Draw on the iOS and Android apps. On mobile you can also turn on “Add watermark (footer) to signature” if you want one.

Drawing on a phone, trackpad, mouse or stylus

The pen adapts to how you move, but every input device has its own quirks. These tips help you get a signature you are happy to put on a contract.

DeviceTips for a good signature
PhoneUse your index finger, not your thumb. Turn the phone sideways for a wider drawing area, rest the phone on a table, and write at your normal pace rather than slowly tracing.
TrackpadPress and hold the click with one finger while drawing with another, or use tap-and-drag if your laptop supports it. Keep strokes short and lift between letters if needed.
MouseSlow down a little and draw with your whole arm rather than your wrist. A simplified signature — initial plus surname — often looks more natural than a full flourish.
Stylus or Apple PencilThe closest to paper. Rest your palm as you would on a page and sign exactly as you normally do; the speed-sensitive line does the rest.

Sign at your natural speed

Because the line responds to speed, tracing your signature very slowly makes it uniformly heavy. Write it the way you would at a bank counter, and the thick-and-thin rhythm comes through.

Choosing an ink colour

All three colours are valid; pick whichever suits the document and your habits.

  • Black — the classic choice, and the clearest on printed copies.
  • Blue — many people like blue because it stands out from black printed text and looks like an original signature.
  • Red — useful for internal approvals or marking that a document has been reviewed, where your organisation uses that convention.

Initials, in-person signing and other places you draw

Your full signature is not the only thing you draw. Many contracts ask for initials on each page — up to two letters — and the same ink-like pen makes them look as natural as your signature. Save them alongside your signatures so they are one tap away.

The pen matters even more with In-Person Signing, where you hand your phone or tablet to a customer, tenant or patient to sign there and then. People signing on someone else’s device are often unsure of themselves; a pen that responds like ink makes the moment feel familiar rather than awkward. A tablet with a stylus gives the most paper-like result of all.

  • Give the signer room. Turn the device to landscape before handing it over.
  • Tell them about Clear. Knowing they can redo it takes the pressure off.
  • Let them pick the colour. Some people always sign in blue.

Draw once, use everywhere

You do not have to draw your signature every time. Save it to My Signatures and it is ready for the next document, on every device. You can save as many as you like — a full signature, a shorter one, initials — and mark one as default. When a document has several signature boxes, “Apply to all fields of the same type” fills them in one go. See saved signatures.

Prefer not to draw at all? The signature window also offers Type, with six script fonts, and Upload, for a JPG or PNG of your signature up to 5 MB. If you are uploading a scan of an ink signature, our guide on making a transparent signature helps it sit cleanly on the page.

Does a drawn signature count?

A drawn electronic signature is one form of e-signature, and e-signatures are recognised under laws including the US ESIGN Act and UETA, the EU’s eIDAS regulation and India’s IT Act 2000. What makes a signature hold up is mostly the record around it: SignPe logs when each signer was emailed, viewed and signed in the document’s audit trail. For the Indian context, read our legality guide, and see electronic signatures for how the whole process works.
