A good poster has a clear reading order before it has a visual style. Someone should understand what is happening, why it matters, and where to look next. Image generation does not remove that design problem. It gives you another way to explore its solutions. This practical guide develops an original bilingual poster brief that you can adapt to MOSS-Image or another generator. The advice is editorial, and none of the examples below are claimed as tested model outputs.

Write the information before the prompt

Begin with a small content sheet. For a fictional evening concert, that might include a title, a Chinese translation, a date, a venue, and one supporting line. Decide which words are mandatory and which are optional. A common failure in an early brief is to give every element equal importance. The image then has no reason to make the title dominant or the venue secondary. Assign a hierarchy before describing any color or texture.

For this exercise, the title is “AFTER HOURS,” the Chinese line is “夜色之间,” and the supporting line is “An evening of live sound.” These are invented creative materials, not a real event announcement. Keep the two title lines paired in your working document so a later edit does not accidentally preserve one language while changing the other. A bilingual reviewer should check meaning as well as individual characters.

Describe the page in reading order

Start with format and hierarchy: a portrait poster, a large title near the top, an abstract shape occupying the middle, and supporting information along the bottom. Then add a visual direction, such as warm paper with very dark green lettering. This order helps you notice contradictions. If the title must be large and the central illustration must fill the whole frame, the brief may already be asking two objects to occupy the same space.

Design a portrait concert poster on warm cream paper. Place “AFTER HOURS” at the top, followed by “夜色之间” on a separate line. Reserve the middle for a dark green abstract form. Keep “An evening of live sound” small and clearly separated at the bottom. Use generous margins and a strong reading order.

That paragraph is a starting point, not a magic phrase. Its value is that you can inspect the intended result. A viewer should find the title first, read the translation second, and discover the supporting information last. If the preview suggests a different order, revise the hierarchy rather than adding more style adjectives. A short, consistent brief is easier to debug than a long list of competing preferences.

Keep exact text separate from atmosphere

Quotation marks help distinguish intended copy from descriptive instructions. Line breaks can communicate which words belong together. The MOSS-Image user guide specifically discusses explicit line breaks when automatic text layout misses the intended result. Even with clear instructions, proofread the output. A beautifully rendered word with a missing character is still wrong, and a correct title does not prove that a smaller date or address is also correct.

Work from a single copy sheet throughout iteration. After each revision, compare the rendered text against it, including spaces, numerals, and punctuation. For Chinese, inspect the characters at the size at which the poster will be seen. A small preview can conceal a malformed stroke or a substitution. For English, pay particular attention to repeated letters and small supporting text. Review the actual export, not only the browser thumbnail.

Use layout boxes when position matters

A structured layout is helpful when the same information needs to survive several visual treatments. Instead of repeatedly describing “near the top,” give the title a dedicated region and reserve another for the artwork. In MOSS-Image’s documented format, the box uses centered pixel coordinates in y-minimum, x-minimum, y-maximum, x-maximum order. Our feature deep dive explains that convention with a complete teaching example.

Build the boxes from a rough wireframe. Leave space between them, and choose a canvas before calculating coordinates. If you later change the aspect ratio, revisit the layout rather than copying the same values blindly. Position control is useful only when it describes a composition that fits the intended output. The model’s layout interface is experimental, so compare the result with the plan and allow time for revision.

Change one meaningful variable

Once you have a baseline, explore one axis at a time. Try a darker background while keeping the words and regions constant. Then try a different relationship between the English title and Chinese subtitle. Save each version with a short note explaining the change. This is less dramatic than rewriting the entire prompt, but it gives you a clearer account of what improved the poster and what made it worse.

Use a small evaluation sheet: title correctness, subtitle correctness, reading order, margins, and contrast. A version can be visually exciting and still fail a required item. Your priorities may differ for a social preview, a book cover, or packaging. Decide those priorities before choosing the most attractive thumbnail. If a revision fixes one line but breaks another, keep that observation instead of treating the whole iteration as an unqualified improvement.

Finish for the medium

A social banner and a printed concert poster ask different things of an image. Check the final dimensions, crop, and smallest readable text. For printing, confirm the production requirements with the printer rather than inferring them from a model’s pixel count. Where exact typography is essential, consider finishing the final text in an editable design application. A generated composition can remain useful even when a human typesetter handles the final informational layer.

The SVG samples on this site make that distinction visible. Their lettering is crisp because it is authored text in vector artwork; it is not a measurement of model accuracy. Use them as composition references, then run your own controlled experiments with the open weights if you want to assess generation quality. A strong poster workflow combines a clear brief, deliberate iteration, and a final human check of the information people will rely on.
