Final answer:
Documents that contain objects to which transparency effects have been applied usually undergo a process called rasterization.
Step-by-step explanation:
Documents that contain objects to which transparency effects, such as opacity and blending modes, have been applied usually need to undergo a process known as rasterization.
Rasterization is the process of converting vector graphics, which are made up of points, lines, and curves, into raster images, which are made up of pixels. When transparency effects are applied to objects in a document, the software needs to calculate how those effects should be rendered onto the pixels.
By rasterizing the document, the transparency effects are pre-calculated and applied to the pixels, resulting in a final image that can be displayed or printed. This process ensures that the transparency effects are accurately represented in the output.
