Add a Claim Form
You can add your own claim form from scratch, but it is very involved and takes a lot of time.
Step 1: Prepare a background image.
Scan a paper form at a high resolution.
Save the image in the A to Z folder as a GIF, JPG, or EMF.
Hint: On the edit window, GIF image size can be easily adjusted by changing the width and height, but JPG image size cannot be changed. If you save as a JPG, set the compression and smoothing for as small a file size as possible without losing detail, somewhere between 200 and 500 Kb. The larger it is, the longer it will take to print.
Step 2: Create a new blank claim form.
On the Claim Form window, click Add to open the edit window.
Step 3: Add the background image.
In the edit panel, click Add then enter the background Image File Name.
Do some trial printing to make sure it's sized right and is positioned on the page so that it won't get cut off on one side. If using a GIF, you can adjust size by entering Width and Height. You may also have to adjust the xPos or yPos (not the offsets).
Step 4: Add more items as needed.
Click Add, then select the field name to add, then click OK.
Move items by clicking and dragging or by using the arrow keys.
To make the movement larger press Shift while pressing an arrow key.
To select groups of items to move as a unit, press Ctrl while clicking. When you have groups selected, any change you make in the four text boxes at the bottom will apply to all items in the group.
Step 5: Click OK to save the form.
