Translating Assembly-Step Images: Keep the Instructions in Order
A localized assembly graphic can contain fluent text and still be unsafe to follow if a step number, arrow, or part label points to the wrong action. Before publishing a translated instruction image, compare it with the approved original and the product's actual assembly guide. Image translation prepares the visual text; it does not verify the sequence or the physical procedure.

Build a step map before translating
List the source step number, action, part name, and arrow destination for every panel. If the picture uses symbols without words, record what each symbol means in the approved manual. Note any warning that must appear before a particular step. This map gives a reviewer something more reliable than visual memory when the localized image is exported.
Separate editable explanatory text from text printed on the physical product or packaging. A translated label placed over a real button name could make the graphic disagree with the item in the customer's hands. Keep the original file and product documentation available during review.
Translate one representative panel
PicTech AI image translation recognizes text in images, translates it, removes original wording, and reconstructs the background while helping preserve the layout. The page also describes an editor for checking fonts, alignment, size, and placement. Begin with a dense panel containing a step number, an arrow, and a short warning. Review the exported result before processing a full series.
Read the steps in the order a customer would encounter them. Confirm that “before,” “after,” “do not,” and similar conditions retain their meaning. Check whether a translated phrase has moved closer to a neighboring arrow or part. A visually tidy result is not sufficient if the instruction now describes a different component.
Compare words, arrows, and the actual product
For each panel, check four layers:
- Sequence: Step numbers and reading order match the approved guide.
- Part identity: The translated name refers to the same physical part throughout the set.
- Visual association: Arrows, circles, and callouts point to the correct location.
- Safety wording: Warnings and conditions remain adjacent to the action they qualify.
If a label does not fit, adjust line breaks or placement in the editor, then compare the export against the step map again. Do not shorten a safety instruction merely to make it fit. Ask the product owner to approve any substantive rewrite.
Check the final page, not only the file
Preview the image at the size used in the destination listing or help page. Small numbered circles and narrow arrowheads may become hard to read on mobile. The surrounding page should identify the same model and revision as the graphic. Save the source, approved translation, SKU or model, destination language, and revision together.
Before publication, have a qualified reviewer verify the procedure against the product documentation. For broader image sets, the batch translation workflow explains how to test difficult layouts before scaling up. This checklist is an editorial review method, not a claim that an image tool can certify assembly instructions.
