1. A method for creating PDF trapping objects from a PDF page description without knowing a contour description by using a computer for implementing a printing process, the method comprising the following steps: using the computer to generate a colored tiling pattern out of a part of the PDF page description without at least one object located on top to be choked; using the computer for clipping with a mask of a background object; using the computer for clipping with the at least one object located on top, or a text, to limit following frame additions to the at least one object located on top; using the computer for adding a frame to the at least one object located on top using the at least one generated colored tiling pattern in the form of an inner frame between the background object and the at least one object located on top; using the computer for adding a frame to the at least one object located on top while activating overprinting of a background in required object colors; and using the computer for inserting the at least one trapped object located on top into the PDF page description.
