How to write prompts for exact text in MOSS-Image

A poster begins with information. Before choosing a typeface or a background, write down what the reader must take away: a name, a date, a place. Make that small piece of copy your source of truth.

Give every line a job

Here is a studio exercise. Keep the title, event details and visual direction separate:

A portrait exhibition poster on cream paper.
Headline: "TYPE & TEA".
Below the headline, three separate lines:
"24 OCT 2026"
"DOORS 18:30"
"STUDIO 08"
Large black serif headline. Small, quiet event details.
One moss-green circle, generous margins, no other text.

The quoted lines are the content to inspect. The remaining sentences are design instructions. This separation makes it easier to revise one part of the brief without accidentally changing another.

Be explicit about a line break

OpenMOSS recommends English prompts while also supporting Chinese and other languages. Its guide says actual line breaks or \n can help guide text layout, while warning that the result can differ from the request. See the official MOSS-Image user guide.

For bilingual signage, write each language on its own line and describe their relationship. For example, place a Chinese shop name above a smaller English name. Avoid asking for several competing treatments of the same words.

Proofread the pixels

Zoom in on dates, prices, decimal points and punctuation. Compare them with your original copy, including the difference between a hyphen and a longer dash. A convincing composition is not proof that every character is correct.

If a line fails, try a shorter version or give it more space. Change one instruction at a time so you can see what helped. When the wording is contractual, time-sensitive or ready for print, use a design editor to finish any remaining corrections.
