Why is my PDF appearing blurry when I upload it as a sticker design?

A sticker design that looks blurry on upload almost always traces back to file resolution or sizing rather than the printer, and both are fixable in your source file.

• Low resolution: export the PDF at 300 DPI or higher at the final print size.
• Upscaled raster art: enlarging a small image adds blur, so start from a high-resolution or vector source.
• Size mismatch: build the file at the intended sticker dimensions instead of scaling it up later.
• Web images: graphics saved for screen at 72 DPI will not hold up in print.

Rebuild or re-export from a high-resolution or vector master at the correct size, and the preview should sharpen up.
