Layout Your files Instantly: With version 1.2 ImageNest will now have its Mac Layout controls directly in the layout interface so they are always available to the users. No more going to the Layout Button to configure your layout on the fly. Everything is right in front of your eyes. Perfect for a workflow on a large format printer such as the Epson Stylus Pro 7900.

Batch Size Files on Import: Now ImageNest customers can easily batch size files on import. ImageNest has the ability to take an unlimited number of files and resize them automatically before they are sent to our nested layout. Think of the amount of time that could save ! Grab 20 Files, make them all 5 by 7, Grab another 20 make them all 4 by 5. Options for Fit to Size or Fit to Fill allow users to specify how to deal with any difference in aspect ratio. You won’t find this feature in any other software RIP.

Printing of Embedded JPG files inside DNG files: DNG files contain 2 major imaging components. The Camera RAW data (which is the original data that a camera recorded) and a JPG file that contains a bitmap image of all the corrections that have been made to the Camera RAW file. ImageNest is the ONLY RIP on the market that will extract the JPG files and print them. This is a major leap forward in making a full DNG workflow into a reality.
