Rasterization is the process of converting vector graphics into raster (pixel-based) images. Its primary purpose is to translate resolution-independent vector data into a fixed grid of pixels that can be displayed or printed consistently on raster-based devices. Unlike vector images, which scale mathematically, raster images display at a fixed resolution and will appear the same at a given size across different outputs. Many printers operate by placing dots of ink or toner, which means all vector content must be rasterized before printing. If this rasterization is handled poorly, then it can lead to unexpected artifacts or quality loss. Performing rasterization before printing retains control over resolution, anti-aliasing, and detail, which helps to avoid these issues and ensures predictable output.
When this feature is selected, the Rasterize Pages dialog box will open:

•Use the Page Range options to determine the page range to be rasterized:
•Select All to specify all pages.
•Select Current to specify only the current page.
•Select Custom to specify a custom page range, then enter the desired page range in the adjacent number box. Further information about how to specify custom page ranges is available here.
•Use the Subset options to specify a subset of selected pages. Select All, Odd or Even as desired.
•Use the Actions with Objects dropdown menus to determine the action taken for comments, form fields and links when rasterization is performed.
•Use the Type dropdown menu to determine the type of rasterization performed on the document.
•Use the Compression dropdown menu to determine the type of compression used for the rasterization.
•Use the Page Background dropdown menu to determine the fill color for transparent sections of the document when rasterization takes place.
•Use the JPEG Quality dropdown menu to determine the JPEG quality when JPEG compression is used.
•Use the Horizontal and Vertical Resolution number boxes to determine the resolution of rasterized images.
