Hi - We've encountered an issue recently with the automatic thumbnail creation when uploading certain PDFs to the DAM. I'm pretty certain it has to do with the way our pdf documents are exported from InDesign. Some images within the pdf cover page are not showing up in the thumbnail when it gets generated - it appears that the thumbnail creation job may not like the layered .ai files that we are using within documents - some of the graphics are layered gradient shapes saved as .ai files that we link to directly from InDesign, and then exported as pdf.
It looks like flattening these images as TIFF or other before embedding in InDesign and exporting PDF does correct the issue we're seeing when uploading the final PDF to the DAM.
Just wondering if this is a known/expected result with the thumbnail creation tool in the DAM, and if there might be some other method to make this work without reprinting all our pdfs to flatten the images first before we upload to DAM. thanks.
