When I print on A3 or A4 paper looks pixelated, the same for the text manipulation. I use to save designs to .pdf or .tiff and then I open them on Illustrator and modify things, but I don´t want to do that. I love Gimp! I know it´s not a 100% ubuntu question but I guess some ubuntu graphic designers on Linux will have experienced this problem. Thanks!
Gimp is a bitmap editor where images are made of pixels. Check the print definition (
Image>Print size
in Gimp). Below 150PPI things will look pixellated.Illustrator is a vector graphics editor, if you want to edit vector graphics with perfect scaling, use Inkscape.
