CorelDRAW basics: the viewing modes (2) - the Enhanced viewing mode

Enhanced is the best viewing mode and is the default setting in CorelDRAW (If you want to choose another default viewing mode click Tools Options -> click General in the Document list of categories and choose an option from the View mode list box.)

The Enhanced viewing mode displays the best possible quality for your monitor; this viewing mode displays high-resolution bitmaps, PostScript fills and anti-aliased vector graphics.

Aliasing is the process by which smooth curves and other lines (usually the diagonal lines) become jagged (jaggies are stairlike lines that appear where there should be smooth straight lines or curves) because the output device (display monitor or printer) does not have enough resolution to portray a smooth line. In addition, this process often occur when a bit-mapped image is converted to a different resolution. Anti-aliasing is a software technique that smooths out jagged lines by surrounding the jaggies with transparent pixels to simulate the appearance of fractionally-filled pixels.

Additionally, when the Enhanced mode is activated you can activate two more options: Simulate overprints and Rasterize complex effects. These options are useful (or better said, essential) when you want to use your artwork for commercial printing.

Simulate overprints - when you print your artwork, if two ore more objects are overlapping, only the top objects will be entirely visible (and printed), while the non-visible portions of the rest of the objects are automatically removed. If you want to print the non-visible portions of your artwork you can use the Overprint option. The Simulate overprints option allows you to see the resulting colour of areas where overlapping objects are set to overprint.

Rasterize complex effects Use this option when you want to see how these complex effects (bevels, transparencies, drop shadows, etc.) will be printed.
