Comparing Proof Versions
Summary: Compare mode gives you visibility to all available versions of a proof. Additionally, it allows you to compare the versions side by side which makes it easy to verify that all markups and comments from previous versions have been made before applying further comments or make a decision on a proof. Compare mode provides a central location to see all the revision history which could be helpful with any audit trail requirements.
Available for: All reviewers. *Note: reviewers will only see the versions they are a part of.

How does it work?
Compare mode is accessed in the upper left corner of the screen. By clicking on this icon you will see 2 versions side by side.

Each function has been numbered on the screenshot below along with a description underneath.

Decision button |
You are able to make a decision on the proof while in compare mode. This is a great shortcut if you are viewing the new version against the old and verifying that the changes have been made. Please note that the decision button will only display if you are granted “Decision” permissions. See Finishing a Review & Understand Proof Decisions for more details. |

Synchronization on/off |
When you enter compare mode both versions are synchronized together by default. This means that zooming, panning or changing the proof page on one version will automatically happen on the other. This is designed to make it easier to check the differences between two versions at the same zoom and page level. You can also click on the comments and the versions will zoom to the correct ratio - this is a fantastic way to compare versions. You can turn off synchronization by clicking on the lock/unlock icon and it will break synchronization. |

Overlay / Side by side mode |
The reviewer may decide how the proof versions are displayed. Side by side mode shows two versions near each other in separate Proof Viewer windows. Overlay mode displays both proof versions over one another so the differences can be spotted more easily. |

The screenshot below shows two versions side by side. Comment 1 has been clicked on by the reviewer who requested to add the logo. They want to verify that the change was made so they click on the "Auto compare" icon (shown with the large red arrow). The new version will highlight the old text position allowing the reviewer to confirm that the change was made

There is also a color picker next to the "Auto compare" icon that allows the reviewer to choose different highlight colors.

Comparing proofs within the same folder (Business and Enterprise Editions only):
Comparing proof versions has long been one of the staple features in Ziflow. We’ve extended that capability to now compare proofs that are not versioned together. This will help cut down on the “tab sprawl” that often occurs when reviewing multiple individual assets.
For teams that use the Folders to organize their campaign assets, proofs within the same folders can be compared, allowing team members to review all project assets and check them against each other using all of the Ziflow comparison functionalities.
Once you enter proof compare mode you will notice a folder icon at the top bar above the proof image.
This button will open a proof list from which you can choose a proof available for comparison. From that point, you can select the proof that you want to open in a comparison mode.
The proof you selected will immediately open in the Proof Viewer next to the proof image you wanted to compare it with.
Additional Information:
- To use the compare function you must have permission to view all versions of the proof that you wish to compare.
- If the reviewer clicks on compare and only one version exists then both windows will be filled with the same proof version.
- You have the option to decide if the newer version should be displayed on the right or left by changing the setting
inside the Proof Viewer configuration menu.
