3.1. Getting started (F1 START panel)The F1 START panel is the key module that starts work in the Personalizator program, used to define the parameters of a personalized background and start the process of generating finished files. The user can choose to create a new PDF page with a specific net size, bleeds, and color, or use an existing PDF file as a basis for further actions. When using a ready-made document, the panel allows you to precisely set the page range and multiplier (number of repetitions), which ultimately determines the final number of pages generated. It is important that all pages in the selected range are the same size.
Additionally, the program allows you to overwrite the bleed values for the loaded background and specify the inner margin. A very important feature available in this panel is the Repeat all elements on each page of the PDF switch, which radically changes the way data is applied. If this option remains disabled, each page of the background receives a subsequent, unique record from the database. When enabled, the data assigned to the first page of the selected range is duplicated on all other pages within a given set, which is useful when creating multi-page documents for a single recipient.
The F1 START panel also integrates tools that support the correct preparation of the project, such as the function of checking the layout of elements through a preview of the template file (available under the lifebuoy icon). After configuring all the background parameters and importing data in the other panels, the user clicks the START button located here, which initiates the process of generating personalized pages and saving them to disk. All work can be saved as a dedicated project file with the .personalizator extension.
After starting the program, the first step is to determine what the personalized background will be and the final number of personalized pages.
[1] When personalizing a new pdf page, we set its size and bleeds (if necessary). The final page size is the net page size plus appropriate bleeds. We can also set the color of the background page.

[2] When the personalized page is a page or a range of pages from a pdf file, after retrieving them, we determine which pages will be the background pages and how many times the set range is to be repeated. The selected number of pages multiplied by the number of iterations is the target number of pages generated.
Additionally, if the PDF background page has bleeds, we can override their value and set the internal margin. It is important that, when the personalized background is a range of pages, the subsequent pages have the same size.

The Repeat all elements on each page of the PDF option changes the manner of personalization. If it is disabled, each page is personalized with subsequent data, if it is enabled, the personalization data of the first page of the selected range of pdf background pages is duplicated on each subsequent page of the range.
Example.
The background consists of three pages ("green", "red" and "blue") repeated 3x (the final number of pages = 9). The personalization dataset consists of 9 objects: 1, 2, 3, 4, 5, 6, 7, 8 and 9.
When the Repeat all elements on each page of the PDF option is disabled, the collection of final pages and applied personalization objects looks as follows:

When the Repeat all elements on each page of the PDF option is enabled, the collection of final pages and applied personalization objects looks as follows:

Solving the task
Step 1: We start performing the task by loading the ID-Card-background.pdf file [1]. into the program. We then determine the scope of the personalized pages: Start from page and End to page [2], ‘Repeat x’ equal 400 [3], inner margin – 2 mm and bleed - 3 mm [4] (the F1 START panel, subpanel Background: PDF page).

In a situation where we receive a badge design from the customer, we can introduce a check on the correct placement of objects. 
To do this, right-click on the lifebuoy icon (in the preview management panel) and open the ID-Card-example.pdf file.

From now on, if this button is pressed, the indicated file will be displayed in the viewer window.

Let's save the personalization project as, for example ID-Card.pers.
