Fixups that can be used in the Workflow use the kfpx file extension.  Fixups can either be created in Acrobat Pro Preflight or in callas pdfToolbox.

If you want to use a check or Fixup profile from Acrobat Pro, proceed as follows

1. Open the Preflight panel in Acrobat Pro by pressing the shortcut key (CMD)+(Shift)+(X)
2. Select the desired profile or Fixup [4] in the list and under the Options button, select Export Profile [5].
3. Save the kfp file to your local hard disk.

Figure 2: The Preflight panel in Acrobat Pro with a Fixup selected.

4. Open callas pdf-Toolbox, using either the free or paid version of the software and select the menu item Profiles.
5. This opens the Profiles dialog, where you can select the menu item Import Profile [6].
6. Then select the kfp file previously exported from Acrobat Pro and start the import process. The import will convert the kfp file to the required extension kfpx to be processed for the Workflow.
7. By exporting the Profile or Fixup again from callas pdfToolbox a kfpx file is now created in the correct format to be imported into the Workflow.

Figure 3: The Profile dialog in callas pdfToolbox.

To create a custom Fixup use either Preflight in Acrobat Pro or callas pdfToolbox. As both programs are developed by callas software, the procedure for creating checks and Fixup profiles is the same. The main difference is the range of features, as not all features from pdfToolbox are available in Acrobat Pro Preflight.

Creating Fixup profiles or entire process plans requires a thorough knowledge of PDF structures, callas pdfToolbox and at times JavaScript. Training courses are available through your local representative.

To create a Fixup proceed as follows:

1. Start the callas pdfToolbox application and click on Tools > Profiles.
2. Select Create Profile [7]. This will open the Create Fixup dialog.

Figure 4: The Profiles dialog in callas pdfToolbox.

3. In the Create Fixup dialog, enter a Name [9] and a comment if needed for the Fixup and select the desired Type of Fixup [10] from the list.
4. Select the desired options [11] that are available for the selected Fixup Type. Variables can also be entered by clicking the orange arrow [12].
5. Complete the process by clicking OK. This will save the new Fixup within callas pdfToolbox. This Fixup can now be used to create a Profile or be applied in a Process Plan and can also be exported.

Figure 5: The Create Fixup dialog in callas pdfToolbox.

6. Select the previously created Fixup in the Fixup list and click on Export Profile [8] (Figure 4).
7. The kfpx file is now saved. The Fixup is now ready to be uploaded into the Workflow.

In order for the Workflow to correctly display information including variables, a description file in the form of an XML must be created for the kfpx file. Depending on the complexity of the Fixup with or without variables, XML files can be fairly complex.

To create a descriptive XML file, proceed as follows:

1. Open a text editor – Sublime Text or Visual Studio Code for example.
2. Fill the following tags with the appropriate descriptive content.
   • Header [13] – The header should not be changed.
   • Information [14] – Should be adapted according to your needs.
   • Variable Analyze Mode [15] – This information should not be changed.
   • Name [16] – Enter the name of the Fixup that should be displayed in the Workflow. Do not delete the language version "en_US", as it will be used as a fallback for the Workflow. This way you can just enter the name for this language and ignore the second entry of your language.
   • Description [17] – This area can be used to write a detailed explanation of what the Fixup does. If you need multiple language versions of the Fixup, this can also be added here.
   • Variables [18] – If variables have been added in your Fixup, e.g. selection lists for certain values, the variable descriptions including all options must be entered in this node. If no variables are used, remove this node.
3. Finally, enter information that will help the user find or filter the Fixup. Enter this information under the Category [19] lines.
4. Save the XML file under the same name as you saved the kfpx file before. Now you have created the second required file. At this point the Fixup can be uploaded into the Workflow.

Figure 6: The XML structure for the Fixup, which was described in Figure 5.

After you have exported a kfpx file from callas pdfToolbox and created the corresponding XML file, you can now upload these files into the Workflow. Proceed as follows:

1. Select the menu item Administration > Settings.
2. Select the Preflight & Fixup tab [20] 
3. In Correction Profiles panel click Upload [21] in the footer.

Figure 7: The Preflight & Fixup tab.

3. The Upload pdfToolbox-Profile and XML-Translation dialog will open with two dropzones, one for the .kfpx file [22] and one for the XML file [23]. Load the respective files into the drop zones by clicking and dragging or clicking on the upload zone and use file management to locate your files.
4. Then enter an internal Key [24] which is used to call the Fixup via a REST call from an ERP system. The Fixup is named based on the title of the Fixup in the xml file.
5. Complete the process by clicking on OK.

Figure 8: The Upload pdfToolbox-Profile and XML-Translation dialog.

You can select the Fixup in two different places.

To apply a Fixup in the Data Preparation tab, perform the following steps:

1. Select the Data Preparation tab in an Article, Order or Production Job.
2. Locate your desired Fixup by filtering Fixups using: Categories, Actions [25] or Text criteria.
3. The results will be displayed in the Fixups panel [26] or Custom Fixups [27].

Figure 9: The Data Preparation tab for an Article.

While the user can access all available Fixups under the Data Preparation tab, a specific set of Fixups (Fixups that are most frequently used in prepress), are available under the Print Data tab [28]. These Fixups are grouped thematically. Fixups that are relavant for the Document Information area can be selected in the footer [29].

If you find yourself selecting the same Fixups over and over, you can mark a Fixup as a favorite. In the footer of the Document Information and User-defined Fields area you will find a drop-down list of all your favorited Fixups [30].

Figure 10: The Print Data tab for an Article.

To locate and select a Fixup, use one of the two options mentioned above. To apply a Fixup, proceed as follows:

1. Select the desired Fixup [31] either under the Data Preparation tab or the Print Data tab. In our example, our previously created and uploaded Fixup Remove existing objects outside the TrimBox is selected.
2. In order to apply the Fixup to the selected print item in the Print Data tab, you'll need to click the Apply button. In Print Data view it is sufficient to select the Fixup in the drop-down menu and release the mouse button.
3. This will open the Remove existing objects outside TrimBox dialog, where you cannot make any further changes in the dialog. The Name [32] and the description [33] of the Fixup are taken from the XML file and are displayed in the dialog.  The majority of Fixups in the Workflow allow or require that the user enter specific settings or variables to complete the Fixup rules.
4. Press Apply to Selection [34] which will apply the Fixup to the selected Print Item(s).

Figure 11: The Remove existing objects outside TrimBox dialog.

It is not uncommon for customers to deliver multiple iterations of a single Print file, i.e., a red, green and blue version, all of which have the same file structure. Therefore, it can be very pratical to apply the same Fixup to several files at once.

In the Workflow, Fixups can be applied to the currently selected Print Item as well as multiple Print Items. Depending on which menu item you have selected, you will need to proceed in different ways:

The Print Item tab [35] of an Order or Production Job can contain one or more Print Items. In order to select multiple Print Items you must either select the items by activating the checkbox [36] or select all items by clicking on the Select All or Deselect All icons [38]. The amount of Print Items contained in the Production Job and the amount of Print Items that are currently selected is displayed next to each other [37].

If you select and apply a Fixup, all Print Items will be processed in parallel and checked in again as new versions.

Figure 12: The Print Item tab of a Production Job with several Print Items.

In the case of Articles, only one Article can be displayed at a time in the Print Data tab. For companies that manage their print data based on Articles, we offer the possibility to apply a Fixup to multiple Articles as well. Proceed as follows:

1. Select either the menu item Article > Articles or Article > Collections. This will display either the Article List or the Collection List.
2. Locate the desired Articles in the list or the Collection.
3. Select the Articles [39] in the list or Collection and under the Process drop-down select Apply Fixup [40] in action bar.

Figure 13: The Article List view.

4. After clicking on Apply Fixup the Apply Fixup to selected Article(s) dialog is displayed.
5. Find your desired Fixup.
6. Select the Fixup [41] and then press Apply [42], which will open the Remove existing objects outside TrimBox Fixup (see Figure 11).
7. Confirm the dialog by pressing Apply to Selection button. The Fixup will then be applied to all selected Print Items.

Figure 14: The Apply Fixup to selected Article(s) dialog.

Fixup Chains can be applied to individual Print Items/Articles as well as to multiple Print Items/Articles at once.

To apply a Fixup Chain in Print Data view, proceed as follows:

1. Switch to Print Data view in an Article, Order or Production Job by selecting the Print Data tab [53].
2. In the footer of the Document Information and User-defined Fields panel you will find the Fixup Chains icon [54]. Click on it to open the Apply Fixup Chain dialog.

Figure 18: The Print Data tab of an Article.

3. In the Apply Fixup Chain dialog you can select your desired Fixup Chain in the drop-down [55]. For the sake of clarity, all Fixups that will be applied are displayed in list form.
4. To apply the Fixup Chain, click Apply to Selection [56].  

Figure 19: The Apply a Fixup Chain dialog.

If a Fixup Chain should be applied to several Print Items/Articles, proceed as follows:

1. Select either the menu item Article > Articles or Article > Collections. This will display the Article List or the Collection List.
2. Locate your desired Articles in the list or the Collection to be edited.
3. Select the Articles or a Collection [57] and click on Apply Fixup Chain [58] in the action bar.
4. This will open the Apply a Fixup Chain dialog (Figure 19). Select your desired Fixup Chain and click on Apply to Selection [56].

If for example a customer's print data is always delivered in the same quality or if print data for certain products are always created in the same stage of development by an upstream Web2Print portal, this print data can be automatically processed using Fixup Chains when uploaded into the Workflow. Fixup Chains can be applied in two different ways when directly uploading print files in the Workflow: Hotfolders and Force Print.

A Fixup Chain [60] can be selected under the Process Parameters tab [59] in the Hotfolder Setup dialog.

Figure 21: The Hotfolder Setup dialog with the Process Parameter tab selected.

A Fixup Chain [62] can be selected in the Data Preparation panel [61] under Automation > Force Print.
