The present invention provides an improvement of the direct lighographic printing plate making process using ink-jet printing, which provides a printing plate having excellent resolution. Accordingly, the present invention provides an improvement of a process for producing a lithographic printing plate comprising selectively forming a light transmittable oxygen barrier film on a photopolymerizable layer of a photosensitive plate, exposing to light and then removing uncured portion on which the oxygen barrier film is not covered, wherein a protective layer which is capable of transmitting oxygen gas and the light to cure the photopolymerizable layer is formed on the photopolymerizable layer, a photosensitive plate therefor and an aqueous ink composition therefor. |
