Abstract
A method of producing positive multicolor proofs electrostetically including the steps of charging a photoconductor, exposing the charged photoconductor to a negative film, forming a latent electrostatic image on the photoconductor, transfer toning said latent image by virtual contact with a donor member carrying an electrostaticially deposited toner layer. The image remaining on the donor member is transferred to the printing stock paper forming the positive proof. Multiple images are formed from successive film negatives and transferred successively on the printing stock. The deposited form layer is split, between the charged areas on the photoconductor and the image areas on the donor member.
