Export is not pixel perfect
Many times when exporting an image file, Illustrator creates a blurry line near the edge of the image, even if the design extends all the way to the edge. Sometimes an extra pixel is added to the exported file. This is because the artboard is not set to a whole number intersection (XY coordinates having decimals). You can re-align your artboard to a whole number intersection to avoid this, but it can take a very long time to do manually when you work with multiple artboards. A solution would be an option for snapping the artboard to whole XY number intersections. This will ensure perfect pixel exports and you don't have to worry about it anymore. We need a solution to ths. Exports should ALWAYS be pixel perfect even though XY coordinates are not whole. Make it snap or make it pixel perfect anyway.
Google translate: The same thing happens to me, when we have many work tables at different sizes, I add that although the pixels are perfect in the work table, the image exports are either at 1x or 72dpi, most of the cases do not match the size of the table working and there is no way to export exactly the size it should go.
Me pasa lo mismo, cuando tenemos muchas mesas de trabajo a diferentes tamaños, añado que aunque los pixeles sean perfectos en la mesa de trabajo, las exportaciones de imágenes ya sean a 1x o a 72ppp la mayoría de casos no concuerda con el tamaño de la mesa de trabajo y no hay manera de exportar exactamente el tamaña que debe ir.
Hans, your previous request about the same issue has been merged into a more general one. This one has to be merged as well. Why do you keep posting this as a separate request? To bring some attention to it and not to the main one, and dilute the applied focus? :)
