20130327239, Dec 12, 2013

Filed:

Jun 12, 2012

Appl. No.:

13/494504

Inventors:

Ragy Adly Isaac - Oak Brook IL, US
John Sheridan Richards - Barrington NH, US

Assignee:

Goss International Americas Inc - Durham

International Classification:

B41F 1/18
B41K 1/38

US Classification:

1014501, 101335

Abstract:

A method of controlling the ink feed to a printed substrate in a lithographic printing press is provided which includes providing, for each of a plurality of ink zones, an ink coverage requirement for a printing unit of the lithographic printing press; color scanning a first ink zone of a plurality of ink zones on a printed substrate as it exits the printing unit of the lithographic printing press; calculating, for each one of the plurality of ink zones, a dynamic flow change based on the static flow change for said each one of the plurality of ink zones and the ink coverage requirement for said each one of the plurality of ink zones; and providing a flow setting for each one of the plurality of ink zones based on the dynamic flow change for said each one of the plurality of ink zones.

Appl. No.:

8/414079

International Classification:

B41F 1312

US Classification:

101485

Abstract:

A continuous web printing press (100) having a control system (202) for automatically identifying which one of a plurality of paper webs (108, 120) is running through which one of a plurality of compensators (146, 148) is provided. First and second marking devices (138, 140) apply reference marks (142, 144) on the respective webs (108, 120) to uniquely identify each web (108, 120). Preferably, the reference marks (142, 144) are comprised of a magnetized material, such as a magnetized label. A sensor (154, 156) is positioned at each of the compensators (146, 148) for sensing the reference marks (142, 144) located on the web (108, 120) running through the compensator (146, 148) to automatically identify which web (108, 120) is running through which compensator (146, 148). The marks (142, 144) on the web (108, 120) are preferably positioned on the webs (108, 120) to uniquely identify the webs (108, 120). A computer circuit (200) uses this information to control the path lengths of the webs (108, 120) via the compensators (146, 148).

International Classification:

B32B 3110

US Classification:

156353

Abstract:

A marker applying device (50) for a substrate (14) having a plurality of markers (70) having magnetic material (74) in a backing (72) of the markers (70), and an adhesive (76) on a front surface (78) of the backing (72), a marker retainer (62) having a relative weak magnetic force at spaced locations (64) for releasably retaining the markers (70) at the spaced locations (64) in a configuration with the adhesive (76) facing outwardly from the retainer (62), an electromagnet (88) positioned with the substrate (14) being intermediate the electromagnet (88) and retainer (62), and the markers (70) being sequentially positioned by the retainer (62) in a configuration with the adhesive (76) facing the electromagnet (88) and substrate (14), and a device (CPU) for electrically pulsing the electromagnet (88) to produce a relatively strong magnetic force, such that the electromagnet (88) removes the markers (70) from the retainer (62) and deposits them onto the substrate (14) such that the adhesive (76) on the markers (70) retains the markers (70) on the substrate (14).

International Classification:

B41F 2700

US Classification:

101485

Abstract:

A printing press with a page cutting control apparatus (11) for controlling cut-off registration in a rotary printing press (10) includes markers (30, 32, 51, 53) for printing reference marks (36) on webs (20, 23) with magnetizable ink having magnetic particles therein, magnetizers (62, 64, 65, 67) for magnetizing the reference marks, sensors (121-124) for magnetically detecting the reference marks, and a controller (140) for changing the web length in response to the detecting.

International Classification:

B41F 3500

US Classification:

1014241

Abstract:

A device (10) for heating ink on a printed web (12) from a printing press (14) having a tunnel (16) defining a chamber (18) which has an inlet (20) for introducing the web (12) into the chamber (18), and an outlet (22) for removing the web (12) from the chamber (18). The device (10) has a microwave power source (24) for introducing microwave energy in the chamber (18) in order to heat the web (12) and heat set inks on tile web (12).
