A printing system includes a product inspection unit configured to perform product inspection on a print product based on a scanned image generated by reading the print product with an image printed thereon and correct answer images stored in advance, a post-processing unit configured to perform post-processing on the print product, and a control unit configured to, upon occurrence of a jam in the print product, control the printing unit to perform reprinting, wherein, upon occurrence of a jam while the post-processing is performed, the product inspection unit is notified of identification information regarding the print product on which printing is started by the reprinting, and wherein, based on the identification information, the product inspection unit references any of the correct answer images corresponding to a scanned image generated by the reprinting and performs the product inspection on the print product.

A solid particle aerosol development device form fogs of solid (e.g., frozen) fountain solution particles that are charged, and brings the charged solid fountain solution particles into proximity of an electrostatic charged image pattern on a imaging member's charge retentive surface. The charged solid fountain solution particles bond to the charge retentive surface at the charged image pattern to develop that image into a fountain solution latent image. The solid particle aerosol development devices produce solid fountain solution particles to develop electrostatic latent images while mitigating issues of evaporation and vapor production, and thus may apply fine films of fountain solution which may otherwise evaporate. In examples, the fountain solution aerosol development devices may include an anilox member, a metering member in contact with the anilox member, a fountain solution reservoir, a particle charger and a particle delivery baffle.

Ink-based digital printing systems useful for ink printing include a photoreceptor layer configured to receive a layer of liquid immersion fluid. The liquid immersion fluid includes dampening fluid, dispersed gas particles, and charge directors that impart charge to the solid particles. The photoreceptor surface is charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged liquid immersion fluid adheres to portions of the photoreceptor surface according to the electrostatic latent image to form a fountain solution image. The fluid portion of the fountain solution image can be partially transferred to an imaging member and/or transfer member to form a dampening fluid image, either or both of which may be electrically biased. The dampening fluid image is inked on the transfer member, and the resulting ink image transferred to a print substrate.
