Lesson 12. Customizing PDF Output Qualit... > Comparing color, grayscale, and mono...

Comparing color, grayscale, and monochrome images

Now you'll examine a gallery that shows the same area from each of the three images that you have worked on. The images have been converted with the ScreenOptimized job option in Distiller using a variety of compression and downsampling settings appropriate for display on different devices.

1.
In Acrobat, choose File > Open. Select Compare.pdf in the Lesson 12 folder, located inside the Lessons folder within the AA4_CIB folder on your hard drive, and click Open.



2.
Zoom in as needed to compare detail between the different image versions.

You'll notice that images with larger file sizes do not necessarily yield better display quality. Downsampling a monochrome file may not significantly reduce its size. When converting your images to PDF, choose compression and resampling options that will give you adequate quality at the smallest file size possible.
