AI business card design: generate art, set contact text yourself

For a business card, generate the artwork without text and typeset the name, phone and email yourself. Image models misspell names and scramble digits, and a card with a wrong digit is useless. On Sume, ask for a landscape ratio such as 3:2, which FLUX.2, Seedream and Nano Banana list, and leave an empty zone where the text will go (Image API).

Request the artwork

Say "no text, no logos" and describe the empty zone: "left half calm and plain, pattern on the right". Ask for png if you will edit it, then place the result in your design tool at the printer's size with its bleed.

curl -X POST https://api.sume.com/v1/images \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "black-forest-labs/flux.2-pro",
  "prompt": "Business card background, soft indigo gradient with fine line topography on the right, left half plain and calm. No text, no logos.",
  "aspect_ratio": "3:2",
  "output_format": "png"
}''

If you want text in the image

For a short company name, a model that renders text well may be fine: quote it, say how often it appears, and check the spelling. Keep phone and email out of the image. If you only need a logo-like word, treat it as artwork and still set the real text in layout (text in images).

Resolution for print

Check the printer's pixel requirement against the image you got; if it is short, see the 300 DPI sizes post and the upscale API (print sizes).
