Low quality/resolution PDF exports

We see an issue with Express heavily compressing images in the PDF download. This is a reproducable problem more extreme than that described by the OP, yet unrelated to the solution reported by Oh.N8.

An appropriately-sized and sharp 300dpi image looks OK on screen in the Express layout, yet becomes unnaturally compressed in the PDF download, making it unsuitable for print.

Further, we have two pages in a project. One generates a PDF that looks just fine, while the second has this issue. Both pieces use the same elements, type, overlays—only the image changes. On the bad pdf the compression is less drastic when the image is perfectly sized—but is still worse than the result we get if we open that .pdf in AI, swap out the image (optimal or oversized), and print again the PDF at the DPI we need for print.

We tried feeding Express CMYK and RGB images, and both sizing and not sizing optimally, at different DPIs. The PDF download is heavily compressed and not suitable for print.

Hey @Schadow 
This is a good question. 
PDFs in Express are either documents or for printing. As a result the colour resolution is going to be different.

For social media posts, definitely use Jpg or PNG. You could get creative and add a bit of motion/ animation to the social post as well. That way your social post would really pop and stand out.

Then you can download or create a social post directly from Adobe Express. 🙂 Save you time downloading and uploading.

If you want to maintain the colour vibrancy then download as a Jpg or Png. However, if you are planning to print the images the PDFs will not be as vibrant.

Monitors tend to have more vibrancy than paper. Adobe PDFs take that into account and give you a CMYK PDF essentially.

Thank you, @Oh.N8, though I'm noting a drop in the actual pixel count/dimensions, not the colorspace differences of CMYK vs RGB. I'd expect that whatever source resolution is used for a project in Adobe Express would be exported to the PDF. No?

Hey @Schadow 

Print is CMYK: colour resolution "drops" Printers don't have the same colour vibrancy that we see on screen.
Screen is RGB: colour on screen tends to pop and be more vibrant.
