A method for mounting one or more printing plate segments on a carrier sheet. The method comprises importing a file into a computer associated with a mounting unit. For each printing plate segment, the file includes a printing plate segment identifier, information regarding alignment of registration marks relative to the carrier sheet; and image data corresponding to a characteristic pattern associated with each printing plate segment. A composite image depicting the image data corresponding to the characteristic patterns is then displayed on a display in the predetermined arrangement of one or more printing plate segment locations and orientations. A mounting unit and a printing system and computer readable media programmed with instructions for performing the method are also described.

According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is measured using a glass roll at a lower temperature than the fountain solution. The lower temperature causes the fountain solution to undergo a change in state and in a solid state the fountain solution crystalizes and changes roll opacity with the thickness of the film. When radiated with a light source the opacity is continuously measured through the surface of the roller. The thickness of the crystallized fountain solution can then be determined via the opacity level increase by the crystallization and the impact to the opacity on the glass roll.
