An imaging apparatus (10) to image wise expose desired microcapsules (38) within a photosensitive media (44) with an image exposure device (12) to harden the desired microcapsules applying pressure to the exposed photosensitive media rupturing the unexposed microcapsule (40), releasing the image-forming material (48) encapsulated within to form an image on the photosensitive media, the exposure device having a molded lenslet array (14) with a printed lens mask improving channel cross talk, aberrations, and reducing flair.
