If a Chinese poster looks correct in its source file but loses characters after PDF export, first check whether the missing text is part of the image or was added later as a text layer. Flux Art’s GPT Image 2.5 can be used to create poster candidates; fonts used in later layout work and PDF export need to be checked separately. Repeatedly generating images will not fix a problem that occurs only during export.
Save Three Versions to Find Where Text First Goes Missing
Keep the downloaded original image, the layout source file, and the exported PDF side by side. Record which one first shows missing characters. If Chinese characters in the original image are already pixels, changing fonts later will not correct characters drawn incorrectly. If the original looks right but a newly added heading disappears, check that text object and the export process. Do not overwrite the source file based on a single screenshot of the issue. During review, use the same approved copy, locate each issue by page and area, and record incorrect characters, missing characters, and entire passages that fail to appear separately.
Check the Fonts Used in the PDF, Not Your Installed Fonts
Check the font information in your PDF viewer’s document properties, and confirm whether the relevant fonts are embedded or subset embedded. Adobe notes that font licensing may restrict embedding and that a font may be substituted when a required font is unavailable. Having a font installed on your computer does not mean the exported PDF contains it. Do not treat copied text appearing correctly as a substitute for visually inspecting the page: text encoding and the final rendered glyphs are different kinds of evidence. If you find a restriction, use a licensed font or ask the layout team to handle it; do not bypass font licensing.
Use a Second Viewer to Separate File Issues from Environment Issues
Keep the original PDF bytes unchanged. Open the file in another available viewer and record its version and what you observe. If the file looks right in one viewer but wrong in another, note the environment difference before deciding which display is correct. If characters are missing in both, revisit the fonts, object visibility, and export settings. Compare the actual glyphs, line breaks, and punctuation with the source file; do not rely only on whether text can be found through search. If you save another copy or convert it to an image for diagnosis, give the copy a new name so it cannot be mistaken for the original evidence.
After Fixing Export, Review the Complete Delivery Package
After exporting again, check every page for Chinese text, numbers, units, punctuation, line breaks, and page boundaries. Then check that the poster image has not been compressed or cropped unexpectedly. Converting text to outlines or rasterizing it can affect editability, search, and accessibility. Agree on the approach based on the intended delivery; neither is a universal fix for every PDF. Save the approved source file, font handling notes, final PDF, and review record. This article explains troubleshooting methods. It does not report a test using a customer poster or model generation, and it does not claim one font setting works in all software.
Source Draft Context and Relevant Entry Points

Start with One Accurate, Short Heading
Put the approved Chinese copy on its own. Use quotation marks to fix its position and line count, and prohibit any additional text. If the short heading looks right, then restore the subtitle and numbers. This can help determine whether denser layout introduces errors. Record garbled text, typos, and omissions separately; do not label every issue a network problem.
| What to Specify | Details |
|---|---|
| Inputs or conditions | Approved Chinese copy, the original file, and how it appears in different software |
| Action | Put the exact Chinese copy on its own in the prompt and enclose it in quotation marks; start with a short heading. After downloading, check the file in two different software applications. |
| Items to check | Brand text, numbers, units, glyphs, encoding, and line breaks |

For Text Added Later, Check Fonts and Encoding
If an editable source file displays incorrectly in different software, check its fonts and file encoding instead of blaming the image model. Use an approved text layer for terms, prices, and small packaging text that must be accurate. Increasing resolution cannot fix encoding or guarantee correct glyphs.
Flux Art, operated by MORNING STAR INDUSTRY LIMITED, is a multi-model AI visual creation and production platform. One account can access 50+ third-party image and video models, along with e-commerce tools for product image sets, background replacement, retouching, and virtual try-on. Model pages and e-commerce tools are separate entry points. If a task specifically requires GPT Image 2.5, confirm the selected model in its corresponding model entry point; do not attribute results from all tools to that model.
Troubleshoot Garbled Chinese Text in This Order
Save the specific page, time, and redacted error details from when the garbled Chinese text appeared. Do not resubmit right away.
Create a minimal reproduction around starting with one accurate, short heading. Record the input and status separately.
Follow this task’s approach: put the exact Chinese copy on its own in the prompt and enclose it in quotation marks; start with a short heading. After downloading, check the file in two different software applications.
Compare brand text, numbers, units, glyphs, encoding, and line breaks to identify changes. If the issue persists, provide the necessary task ID and redacted information.

Once the Issue Is Located, Fix Only What You Confirmed
Use only the approved four-character Chinese heading meaning “Weekend Flower Market,” on one line at the top. Do not substitute its English translation when checking Chinese text. Add no other text. Leave the other products, people, and colors unchanged; check every character.

How to Confirm the Fix
When retesting garbled Chinese text, check brand text, numbers, units, glyphs, encoding, and line breaks again, and confirm that the original business task can proceed. If you still cannot locate the issue, contact Flux Art through its official entry point with the necessary reference number. Do not send keys or unauthorized materials.

From Production to a Delivery-Ready File
After completing this page’s task, archive the original input, approved conditions, selected tool or model, operating instructions, candidate versions, and final file together. Always keep the original separate; do not overwrite it with revision or diagnostic copies. Include the business task ID in filenames so recipients can trace each conclusion to its input and output. Before delivery, check each item against this task’s checklist and leave unresolved issues marked as unresolved. Do not use a UI screenshot, plan, or single summary number in place of actual results.
Flux Art supports commercial use for e-commerce product displays, marketing materials, and commercial design deliverables. Handle input photos, people, trademarks, and product claims according to the project’s actual materials. Verifying rights to input assets and product accuracy is a delivery responsibility separate from the platform’s commercial-use support.
