Using an Anti-Aliasing Plugin for Photoshop
An anti-aliasing plug-in helps in the removal of jagged edges from a graphic and makes them much smoother and prettier to look at. The following article takes a look at using an anti-aliasing plug-in for Adobe Photoshop.
How to Use Anti Aliasing
Anti aliasing, or more popularly called AA, is not an after step or a postproduction thing when it comes to Adobe Photoshop. It has to be embedded within the process. You simply cannot take a rough image and process it to remove the jagged edges. The Anti aliasing (AA) process is to be specified while an element is being rasterized (i.e. being converted from a vector form to an image).
How the Plug-In Works
An Anti aliasing (AA) plug-in generally works by using an edge detection and pixelation detection algorithm that allows it to detect evidence of aliasing and replace it with semi transparent pixels.
Using the Anti aliasing (AA) Plug-In
Simply select the image or text element and choose the plug-in from the relevant drop down menu. This will provide a settings box that can be used to change the degree of Anti aliasing (AA). You can do this by changing the amount of pixels selected for filtering.
You will need to set max trail-off to a slightly lower value to avoid loss of crispness and set the max trail-off size to half the size of the area. Also use transparent edges if you are working on layers to avoid any unwanted semi transparent pixels from showing up.
