Quality rejection: resolution vs AI artifacts? (JPEG & PNG)

はじめまして。添付のAI生成画像が品質の問題で却下されました。同一の画像をJPEGとPNGの両方でアップロードしていますが、いずれも却下されています。解像度や圧縮などの技術的な画質の問題なのか、それともAI特有の不自然な質感や演出過多、ストック素材としての不適合が品質の問題と判断されたのか分からず、改善点についてご意見を伺いたく投稿しました。特に問題になりやすい点をご指摘いただけると助かります。よろしくお願いいたします。

PNG file format is supposed to be used only for images with a transparent background.

AIで生成した画像を拡大する過程で、過剰に拡大しているためぼやけてしまっています。

画像を100%まで拡大表示して画質を確認してから投稿してください。

同じ画像をJPEGとPNGの両方で投稿する意味はありません。

過剰に投稿するとスパム扱いになる場合があります。

 

通常の画像のアセットならJPEGです。

透過がある場合はPNGで投稿します。

 

重要なことが書かれていますので、コントリビューターガイドをよく読んでから投稿するようにしてください。

Thank you for the clear explanation. I understand that over-enlarging AI-generated images can cause softness and blur, and that assets should always be checked at 100 percent before submission. I also understand that submitting the same image as both JPEG and PNG has no benefit and may be considered spam. I will submit JPEG files for standard images and use PNG only when transparency is required. I will carefully review the Contributor Guide before submitting future content. Thank you for the helpful advice.

First, png images should only be submitted if the asset has a transparent background. I've circled just a few of many rendering errors, which result in the quality issues. Inspect your assets at 100% or higher prior to submission and fix such errors if you can.

Thank you very much for taking the time to review my image and for clearly pointing out the rendering errors. I now understand that PNG should only be submitted for assets with transparent backgrounds and that these AI rendering artifacts are the main cause of the quality rejection. I appreciate you highlighting specific problem areas. I will carefully inspect my assets at 100 percent or higher and address these issues before submitting new content. Thank you for the helpful explanation.

Do not submit duplicate content in multiple file types. That's considered spamming.

  • JPEG is for photorealistic images. 
  • PNG is for transparent images only.
  • Remove Text. If desired, customers will add their own fonts, languages & text after purchase. 

 

Read the submission requirements in your Stock Contributor User Guide. 

Hope that helps.

Thank you for the explanation. I understand that submitting duplicate content in multiple file types is not allowed, that PNG is only for transparent backgrounds, and that text should be removed. I will review my assets at 100 percent and fix rendering errors before submitting again. Thank you for your help.
