If your images are pixelated on screen at 100%, it will be printed this way.
Pixelated artwork example:
Please check your artwork carefully before ordering. We cannot be held accountable for pixelation due to poor imagery, resizing etc.
To minimise the risk of pixelation, ensure all images are 300dpi or higher. Your file artwork size should also match the desired printed paper size.
E.g. upload A4 artwork for A4 printing. Do not upload A4 artwork for A3 printing, as this will distort the artwork.
