Scale/measuring 100% between Adobe products

[paulwieczorek]

Hello,

we've found inconsistency when measuring 100% zoom on THE SAME FILE between different Adobe products. The Photoshop renders the file exactly as it should while Acrobat renders it smaller - to obtain the same distance of the red line one must zoom up to 150% in Acrobat Pro DC.

Anyone have any clue?

Photoshop is a pixel-based application, so 100% means one image pixel equals one screen pixel. Other applications that are not strictly pixel-based (InDesign, Illustrator, Acrobat…) may define 100% as the print size, which is rarely the same as a 1:1 pixel view. The inconsistency happens because in a way, both definitions of 100% can be correct, depending on the context.

However, on top of that, a print size view is only accurate if the application knows the actual resolution of the display, and that isn’t always accurate. You can probably reconcile this in Acrobat DC preferences. In the Preferences dialog box, click the Page Display panel and look for the Resolution option. If the "Use system setting" resolution option doesn't make 100% match Photoshop, adjust the "Custom resolution" number until it does.
