Proof Ink

Business cards · foil stamping first

Made it with AI?
Now make it printable.

Upload your AI business card design and we'll turn it into a file your print shop will accept. And we'll show you exactly how the foil will look before you order.

What the AI gave you

Looks great, but print shops will reject it

What we turn it into

MOONLIGHTstudio · seoul

A print-ready file, plus a preview of the foil

The image above is illustrative. Actual conversion results and previews vary by design.

Ever gotten stuck trying to send a design to print?

“The file doesn't meet spec.”

AI gives you an image. Print shops need a print-ready file. Nobody tells you how to get from one to the other.

“Foil needs a separate plate.”

You have to mark which areas get foil stamping on a separate file. First time you hear this is when your order gets rejected for it.

You don't find out until it's too late

It looks great on screen. The real thing can look different. The most expensive way to learn that is after 200 cards are already printed.

Three steps, that's it

  1. 1

    Upload your design

    PNG or JPG works. If the resolution's too low, we'll tell you right away.

  2. 2

    Paint where the foil goes

    Brush over the logo, the text, whatever you want to shine.

  3. 3

    Preview it, then download it

    Check a realistic preview, then download your print-ready file bundle.

Previews are for reference and may differ from the finished print. Foil color and shine vary by paper, print shop, and lighting.
