Adaptive Resolution (AR) Preference in QuarkXPress 10.2

Background

QuarkXPress 10 has an adaptive resolution (AR) mechanism that shows the best available resolution for each image, depending on zoom level and display. It is not a simple hires/lores resolution anymore and it is not a preview, you see the representation of the actual image file (only exception is EPS).                                                                                                                                                                                          

QuarkXPress 10.2 we improved the AR mechanism significantly, which means when scrolling and panning you'll see optimized cached previews. That makes everything much faster than before. Previous versions of 10 didn't do that, which caused the slow down when scrolling or panning.                                                                                                                                                                                    

Plus we introduced a preference to basically turn off AR.                                                                                                                 

How it works

 

  1. When you set the preference to "Quality", AR is turned on and working at its best quality.With that setting QuarkXPress will always show you the best quality for images, regardless whether it is for pixel-based imaged or vector-based graphics.

  2. When you set the preference to "Performance", AR is kind of turned off. With that setting QuarkXPress shows preview images. Preview images are created this way :                

 

  • pixel-based images, QuarkXPress shows a preview with 72 ppi or less, depending on the resulting preview and zoom/scale. QuarkXPress uses 1.25 million pixels as a maximum for previews, meaning if a preview would have more pixels, resolution is dropped.

  • For vector based images, QuarkXPress rasterizes the vectors and shows it with 72 ppi or less, depending on the resulting preview and zoom/scale. QuarkXPress uses a maximum of 20 MB for previews, meaning if a specific preview would have a larger size, resolution is dropped.                                                                                                                                                                                                                                                                                                                                                                                                            

So whenever you have the preference set to "Quality", you see always the best image quality and it works much faster than QuarkXPress 10.0/10.1. When you set the preference to "Performance", then you see previews with 72 ppi or lower (if you use very large images).           

Also, that maybe explains why everybody may see different results, it very much depends on the images that you use .
