Apparatus for providing a background having a desired color and/or pattern on photocopies made of bulky objects comprises a cover for placement between a platen of a photocopy machine and a bulky object, such as a book, to be photocopied. In the preferred embodiment, the cover comprises a clear, transparent, flexible envelope filled with a white liquid. The cover is placed on a platen of a photocopy machine, and a book to be photocopied is placed face-down on the cover. The weight of the book, or pressure applied on the book, forces the white liquid out of the area between the pages of the book to be photocopied and the platen, allowing the photocopy machine to "see" the page or pages to be photocopied against a white background. A photocopy reproduces the page on a white background, instead of the black background which is usually present in a photocopy, made without the cover, of a page of a book.
