Methods for printing using printing systems comprising a flexible intermediate transfer member (ITM) disposed around a plurality of guide rollers at which encoders are installed, and an image-forming station at which ink images are formed by droplet deposition by print bars onto the ITM, can include measuring a local velocity of the ITM under one of the print bars, determining a stretch factor for a portion of the ITM based on a relationship between an estimated stretched length fixed physical distance between print bars, controlling an ink deposition parameter according to the stretch factor so as to compensate for stretching of the reference portion of the ITM.

RECORDING APPARATUS

A recording apparatus includes a supply portion for supplying an airflow, a blowing port that is formed in a slit-like form following a width direction orthogonal to a conveying direction of a discharged medium, for blowing out the airflow supplied from the supply portion, the blowing port being formed with a channel, through which the airflow flows, extending in a direction substantially perpendicular to a conveyance region of the discharged medium, from an inlet side at which the airflow is introduced, to an outlet side, and a supporting member provided on the inlet side of the blowing port to support opposing wall faces of the blowing port, while allowing passage of the airflow. The blowing port has a narrow portion that partially narrows a width of the channel, father on the outlet side than the supporting member of the wall faces forming the channel.

An inkjet image forming apparatus includes: an image former that forms an image on a transfer body by discharging an ink droplet from an inkjet head; and a hardware processor that detects a landing state of the ink droplet that has been discharged and landed on the transfer body and changes an image forming condition when the image is formed so that a detected landing state approaches a target landing state.

IMAGE FORMATION WITH ELECTROSTATIC AND MOLECULAR FIXATION

An image formation device includes a first portion and a second portion. The first portion along a travel path is to receive droplets of color ink particles within a dielectric carrier fluid onto a substrate to form an image. The second portion includes a charge source to emit airborne charges to charge the color ink particles to move, via attraction relative to the substrate, through the carrier fluid to become electrostatically fixed relative to the substrate and to become additionally fixed, in their electrostatically fixed position, via distance-dependent, molecular forces relative to the substrate. The duration of additional fixation via distance-dependent, molecular forces may be at least greater than a duration of the electrostatic fixation.
