Abstract: Photographic prints are produced from a virtual negative image on photographic paper. An image formation device coupled with a source of virtual negative images and a displacement actuator coupled with the image formation device are provided. The image formation device is positioned in a first position. A group of pixels on the image formation device that correspond to a portion of the virtual negative image is illuminated. The photographic paper is exposed to the group of pixels by directing a light beam from a lamp along an optical path. Relative motion is provided between the image formation device and an exposure target. A group of pixels on the image formation device that corresponds to a portion of the virtual negative image is illuminated. The photographic paper is exposed to the group of pixels by directing the light beam from the lamp along the optical path.

Abstract: Device to effect micro-displacements of a support for digital images, in which the digital images are formed by a determinate matrix of pixels arranged in lines and columns perpendicular to each other. Each pixel has a determinate lateral size and between adjacent pixels a free space of determinate amplitude. The device has a fixed structure having an optical axis, support members keeping the support for digital images on a plane orthogonal to the optical axis, and actuator members arranged between the fixed structure and the support for digital images, to displace the support for digital images, along the plane and in the directions of the lines and columns, with respect to the optical axis. The actuator members are associated with electronic control elements and effect one or more unitary displacements, in the directions, each one equal to or less than the determinate amplitude of the free space between adjacent pixels.

Abstract: Photographic prints are produced from a virtual negative image on photographic paper using a mini-lab that has an exposure target and a lamp capable of directing a light beam along an optical path. An image formation device coupled with a source of virtual negative images and a displacement actuator coupled with the image formation device are provided. The image formation device is positioned in a first position. A group of pixels on the image formation device that correspond to a portion of the virtual negative image is illuminated. The photographic paper is exposed to the group of pixels by directing the light beam from the lamp along the optical path. Relative motion is provided between the image formation device and the exposure target. A group of pixels on the image formation device that corresponds to a portion of the virtual negative image is illuminated. The photographic paper is exposed to the group of pixels by directing the light beam from the lamp along the optical path.

Abstract: Operation control device for photography printing and developing machines, wherein the images of negatives are projected on photographic paper, by exposing it, and wherein the exposed paper is then developed and printed. Device comprising central control means (23) communicating with the control unit (19) of each printing and developing machine (6, 7) and displaying means (monitor 17) for the negatives of each machine, contained into magazines (25), wherein such central control means (23) are adapted to set the data of the characteristics of the operative cycles to be carried out in the different machines and to control such cycles, independently from those of the other machines, and to activate at random every machine as soon as one operative cycle is ended, in order to permit a subsequent cycle to be carried out.

Abstract: A plant for the continuous processing and developing of photosensitive material. A plurality of interface units are positioned "in-line" between various units in a line for automatically and continuously receiving said material from "up-line" units and continuously passing said material to "down-line" units. The interface units include a pair of separate groups of pulleys which are axially movable relative to one another.
