Anti-Aliasing – When exporting images to TIFF always make sure the Anti-Alias setting is active. This will make the text look significantly better and the overall card look much nicer.
To diminish the stair-step-like lines in images that should be smooth, by surrounding the jagged edges with shades of color. Anti-alias should remain checked because it smooths the contours of the elements, it makes anything you draw (bitmap) look smooth and not jagged (like steps) at the edges.
You will see the difference when you add text to a graphic.
