Hi Everyone. So I am a Merch by Amazon participant. Their instructions for submitting images for their products are 300 dpi and 4500x5400 for PNG images. Soooooo, I am wondering, is it ok to see pixelation on a png file at the 400 zoom level for 300 dpi in Affinity products? I know I can use a svg if I want no pixelation, but svg's don't work if you have any type of nice gradient on your image. (I know you know all this ). So is the point that those POD houses don't worry about pixelation because 300 dpi is enough? Also, trying to create 300 dpi resolution in Affinity Photo or Affinity Designer doesn't help the look of the image resolution. OR do I have to save the file at the 300 resolution first to see the difference. So confused. Thank you for helping a "newbie who knows just enough to be dangerous" - which means I might not know too much! Thanks for any and all help and explanations to help clear this up. Brenda

Just want to say, after years of using PhotoShop, I was unable to afford upgrade subscriptions when I moved to MACOS High Sierra. Affinity Photo is a tremendous alternative. I recently had this PDF Export problem. A printer I have worked with for years to do postcards told me my PDF Export of a design in Affinity Photo was only 72 DPI. I had set the doc up as a 4x6 postcard with bleed (4.25 inches by 6.25 inches), and choose the default profile for CYMK instead of RGB color. My design contained 3 images. Two of those were video screen captures and were 72 DPI PNGs, while the other was a 400 DPI photo. All the images were reduced more than 50% from their imported sizes, so I thought the PNGs would still get by. The other layers contained limited text and a solid background color. When I exported I chose the PDF (for print) at 300 DPI, using the Bilinear default. I was confused by the Printer's rejection of the PDF, since this is more or less the same way I used to set up PhotoShop docs, and I had used lower res images in the past without the entire PDF being rejected as 72 DPI. I read some info from Affinity regarding "Upsampling" and info about the Bicubic export choice. I then went to Doc Setup and did an Upsample at 300 DPI, which didn't appear to take any time or change anything - because it was already 300 DPI(?) Then I exported the PDF (for print) at 400 DPI and chose Bicubic option, no rasterizing. In the resulting PDF, the PNG images looked a tiny bit clearer on my monitor, but I wasn't sure about printing. Printer said the updated files were good and ran the job (which I haven't received yet). Although what I did worked, it was a shot in the dark. I'm interested to know why this Export to PDF was more involved than what I used to do in PhotoShop.
