The method includes the steps of (a) providing an image film negative comprising a negative of an image on the image film negative, wherein the negative of the image comprises a pattern of opaque areas; and (b) inkjet printing a filtering layer on portions of the image film negative not covered by the pattern of opaque areas, wherein the portions of the image film negative comprise portions where it is desirable to modulate intensity of actinic radiation in a subsequent exposure step.
