Our customer has notified us that some images on the latest pdfs have noticeable jpg noise on the edges of the image. This noise is very noticeable because the images have white background. After researching and testing, we have found that this only happens on images that has been cropped and rotated, and only when the pdf is exported to RGB (with the document being made on CMYK), so the "noise" is generated on colour conversion on the cropped image on export. Attached image shows the noise, which is more noticeable the lower the resolution of the exported pdf. Steps to reproduce: Place an image (with white background for better view of the issue) on CMYK document. Crop the image (in our case, to reduce excessive white area) Rotate the image Export to PDF in cmyk, high res (X1A): image has no issues Export to PDF in RGB, any resolution: image has jpg noise in borders of the crop area We checked and it also happens converting to Gray and limitless RGB, and the noise disappears when there is no pdf color conversion. A stopgap solution is to rasterize the image, but this results in an embedded image, unlinking the original, and also doing it on a 4000 image catalogue is a no-no. Exporting in higher resolution and less compression mitigates the issue, but it is still there. In our workflow, this is an issue, because we made the design for printing and later export a digital rgb version from the same document for web publishing.
