Schmu

Hello. I'm attempting to upload art made in Affinity Designer to Teespring. I export as a PNG, Resample: Bilinear and don't resize the image larger when creating my listing. After creating the listing, the preview looks pixelated. Other shops don't have this pixelation problem on their product pages. I'm concerned about the quality of the shirt. Their design tips say to turn off anti-aliasing in Illustrator. Can I achieve a similar result in Designer to prevent pixilation of a printed product? I see an export option for nearest neighbor but I don't fully understand this or if it will allow my design to be printed with high quality. The artwork are vectors and they are only pixelated when uploaded to the shop. What would you suggest?

In Photo, you can make a pixel selection with one of the selection tools, then Copy or Cut it.
If you didn't Open the image, but Placed it or dragged it into Photo or pasted it into another document then you probably have an (Image) layer rather than a (Pixel), and you'll need to Rasterize the layer before you can operate on its pixels.

Try turning off "Show Snapping Candidates" in the Snapping Manager.
