Why do checkboxes created with Liquid Office Form Designer stamp solid black?

Liquid Office uses grayscale colors for white, black and shades of gray. FDFMerge and FDFMerge Lite expect RGB colors only. You can fix this in two ways:

  1. Use Liquid Office to change the checkbox backgrounds to transparent or any color but pure white, pure black, or a shade of gray.
  2. Using Acrobat, examine the properties of each checkbox field and click Ok. You don’t need to change anything, just click Ok.
