Other Functions

Include PDF/X Output Intent:

Normally, any PDF/X Output Intent is ignored during the comparison because it affects the display of the data. However, if you want to include the Output Intent, you can enable it using the "Include PDF/X Output Intent" check box.

 

Compare within:

Choice of trim box, bleed box or art box as the basis for comparison. Set an art box in Geometry Con­trol if you wish to compare just a certain part of the image.

You can save a report on the results of the comparison as a PDF file. After you click the button, you can edit various settings and select where the file will be stored. Besides this, you can define that not only the two currently selected pages will be compared but also a number of pages in the document. Select "Page Selection > All" and confine the pages to be compared for both doc­uments. Make sure that the number of pages match.
To skip this step and save the report immediately, hold down the Shift key when you click the button.

•"Autostart":

The "Autostart" check box improves communication between the Prinect Cockpit and Prinect PDF Toolbox. Prinect Cockpit features a PDF Compare engine that after Prepare compares the PDF with the original PDF stored in the "Documents\current" folder. The engine also generates a Compare report that you can open interactively in the Cockpit. You can open the PDF file from this report. For PDF Compare to open automatically in Acrobat, you have to enable the "Auto­start" option.
