Plan the words and visual hierarchy, write a clear poster prompt, and review the result before exporting your campaign artwork.
For a social campaign, event announcement or product launch, readable words matter as much as the image. To create a poster with Nano Banana 2.1, settle the exact copy first, describe its hierarchy and placement, then inspect the lettering at the size people will actually see. Leave final typesetting to a design editor when exact fonts or long copy matter.
Use APIXO as the starting point for your image workflow. This guide focuses on creative decisions you can make before generating, while reviewing a draft and before publishing. The example prompts are writing templates, not tested outputs.
Choose the poster’s destination before its style. A portrait social post and a wide event banner need different compositions. Confirm the destination’s current crop and safe areas, then decide what someone should notice first. You do not need to fit the entire campaign into one image.
Check the Nano Banana 2.1 model page for availability and current options. Google’s model reference identifies improved text rendering and infographic layout as update areas. That makes posters a useful task to explore, but it does not establish how a particular poster will perform on this route.
Describe the visual and the words separately. Quote the copy exactly, name its position and specify the reading order. Instructions such as “professional” or “beautiful” do not tell the model whether the headline should dominate or where the supporting line belongs.
Create a portrait poster for [campaign]. Main image: [subject and visual style]. Use this exact headline: “[headline]”. Place it in [position], with high contrast and clear spacing. Put “[supporting copy]” below it at a smaller visual scale. Leave generous space around the text. Do not add other words.
Replace every placeholder with your own brief. Start with a short headline and a restrained amount of supporting text. If your design needs a legally precise statement, a distinctive licensed font or several paragraphs, reserve a clean text area and add that copy in your design editor.
Open the AI Generator, select the image workflow and check whether Nano Banana 2.1 is available in your account. Review the controls and estimate shown for the selected model before submitting. The API’s parameter list is not proof that every control appears in the browser workspace.
Choose an aspect ratio that suits the intended composition. Use a lower-cost draft size when the current quote makes that useful, then inspect whether the layout deserves another attempt. Moving to a larger output does not repair an unclear brief, and a later generation can change the composition.
If the headline is unreadable, reduce the copy or simplify the background behind it. If the layout is crowded, remove a secondary element rather than adding more styling instructions. Save the complete prompt, selected model, settings, output and actual charge so you can compare attempts.
When the available workflow accepts a reference image, use the draft you want to revise and describe one change. Name the elements you want to preserve, then compare the whole image after editing. A request to keep something unchanged is a creative constraint, not a guarantee.
Use the supplied poster as the reference. Change only [one requested change]. Keep [subject, palette and composition details] as consistent as possible. Preserve the exact approved copy: “[copy]”. Do not add new text or decorative elements.
If repeated generations keep breaking the text, finish the image without words and typeset the approved copy yourself. For other creative directions, explore the image model hub; test the same brief before assuming a different model will solve the issue.
Keep aspect ratio and resolution separate: the first describes the frame’s shape, while the second affects output detail and the available size tier. APIXO documents 1K, 2K and 4K for this route. Check the actual exported dimensions and current destination requirements, especially for print; a tier label alone does not establish print suitability.
Review the final file after cropping, compression or typesetting. Check its small-screen appearance as well as the full-size image. Keep the editable layout and approved text alongside the export so a future translation does not require rebuilding the entire poster.
No. Higher resolution cannot guarantee correct spelling, line breaks or meaning. Review every word at the intended display size and compare it with the approved copy. If exact typography is essential, use the generated visual as the background and add the final text in a design editor.
Yes, but treat the adapted copy as a new layout task. Translation changes word length, line breaks and sometimes reading direction. Have the wording reviewed, then adjust text areas and inspect the finished file. A shared, text-free visual can be useful when several languages need separate typesetting.
Open the AI Generator with your approved copy and a clear composition plan. Use the model hub to explore additional workflows when your campaign calls for other formats. Choose the next generation because it answers a specific creative question, then review the output before publishing.
Developers adding this workflow to an application can use the Nano Banana 2.1 Docs for authentication, inputs, task results and errors. The APIXO reference is the source for this route’s integration contract.
