ItemlumeVirtual try-on / PRODUCTION GUIDE
Is the pattern wrong, or is the garment image showing moiré?
Wavy bands over a fine check can be a sampling problem, an altered garment pattern, or both. Identify the stage where the change appears before paying for another image. Compare the untouched source, full downloaded output and actual storefront size, then decide whether the problem belongs to photography, generation or display preparation.
Identify which visual relationship changed
Choose a small, documented area of the garment, such as a check beside a pocket seam. Record the real repeat direction, colors and relationship to the seam. A changed motif, missing stripe or moved seam is a merchandise difference. Broad ripples or unexpected color bands over an otherwise consistent fine repeat can suggest interference instead.
Adobe explains that intricate repeating patterns can produce aliasing artifacts, including moiré. It also recommends checking after resizing. This is a reason to investigate scale, not permission to classify every inaccurate fabric as moiré. A generated shirt can genuinely change its construction while also displaying sampling artifacts.
Create a three-stage inspection record
Keep the original photograph, the unmodified generated download and a capture of the intended display together. Inspect the same patch in each. Use a viewer that can show the image at its actual pixel scale, then inspect the practical display size. A zoomed screenshot already contains another resizing step and should not replace the original file.
| Stage | Question | What it helps isolate |
|---|---|---|
| Untouched source | Are the bands already present? | Photography or source preparation |
| Original generated file | Did motif placement or construction change? | Generation differences |
| Storefront derivative | Do new bands appear only at this size? | Resizing or display behavior |
Record the file and viewer scale with every observation. The purpose is to locate a change, not to force all views to look identical.
Handle a source problem before another request
If the interference is present in the authoritative photograph, obtain a clearer source when the weave or print matters to the purchase. Try another distance or angle and check the captured file before completing the shoot. Keep the garment edition and framing evidence consistent so changing the camera setup does not introduce a different product into the comparison.
An external editor may help reduce visible interference, but preserve the original and inspect what the correction removes. Aggressive smoothing can erase the real fine texture along with the unwanted bands. A smoother fabric is not automatically a more truthful fabric. Use an accurate detail photograph when the general view cannot communicate both the pattern and the overall garment clearly.
Separate a generation rejection from display preparation
In Virtual try-on, use the approved garment references and an uncomplicated pose for the initial candidate. Inspect motif spacing and seam relationships in the actual download. If the new shirt has larger checks or a redesigned pocket, reject the product change even when resizing makes the visible waves disappear.
If the original output preserves the documented pattern but a small display introduces interference, investigate the destination’s resized version before regenerating. Try an appropriately prepared derivative in an external workflow and inspect it at the intended size. Itemlume has no connected dedicated moiré-removal or image-enhancement tool; a new generation is another creative candidate, not a targeted sampling repair.
Release with separate construction and display decisions
For a hypothetical fine-check overshirt, the approval record can say that pocket alignment matches the source, while one card size still produces visible interference. Those are two decisions with different owners. The product reviewer approves construction; the storefront operator checks the served derivative and theme presentation. Do not hide the second issue inside a general approved label.
Use the pattern review guide for repeat and seam fidelity and the pixel delivery guide for file and display dimensions. Recheck after later crops or resizing. Approval at one image size does not establish that a fine textile will remain clear in every derivative.

Frequently asked questions
Do wavy bands always mean the AI changed the fabric?
No. Compare the source, original output and displayed derivative; sampling interference can appear at a particular scale.
Can smoothing remove a real garment feature?
Yes. Review the corrected region against the untouched source so actual weave or fine print is not erased.
Does Itemlume have a moiré-removal tool?
No dedicated moiré-removal or enhancement tool is currently connected. Use an external workflow when appropriate.
