US Patent:

6355398, Mar 12, 2002

Filed:

Sep 1, 2000

Appl. No.:

09/653726

Inventors:

Howard A. Fromson - Stonington CT 06378
William J. Rozell - Vernon CT

Assignee:

Howard A. Fromson - Stonington CT

International Classification:

G03F 7004

US Classification:

430302, 430311, 430330, 430944, 430945, 1014631

Abstract:

A lithographic printing plate or other coated imageable substrate is imaged by heating an area of the coating with an infrared laser and reacting the coating in the heated area with ultraviolet or visible radiation. The coating can be either positive working or negative working. The modulated radiation may either be the ultraviolet/visible radiation or the infrared radiation and the radiation spots are superimposed or the ultraviolet/visible spot may closely trail the infrared spot. The imaging time is reduced since the reaction rate is increased at the elevated temperature.

International Classification:

US Classification:

1562728, 1562744, 1562755, 430300, 430302, 430309, 430945

Abstract:

A metal substrate is treated with a plurality of rotating brushes and a slurry of particulate material such that the treated surface is capable of absorbing incident infrared laser radiation. The substrate is itself capable of being visibly imaged by selective writing with an infrared laser. The substrate is coated with an ablatable coating which is transparent to the imaging infrared laser radiation. Selective exposure to infrared laser radiation ablates this coating in the laser exposed areas as a result of the absorption of infrared radiation by the substrate. The substrate can be anodized after rotary brush graining and still retain its ability to be imaged and ablate a coating. The coated article can be imaged in a computer-to-plate infrared laser imaging device. Depending on the specific coating and substrate selection, the imaged article can be used in a conventional lithographic printing process or in a dryographic printing process.

Appl. No.:

09/691448

Inventors:

Howard A. Fromson - Stonington CT 06378
William J. Rozell - Vernon CT

Assignee:

Howard A. Fromson - Stonington CT

International Classification:

G03F 900

US Classification:

430302, 101141, 1014631

Abstract:

An elongated web of lithographic printing plate stock is intermittently fed to the drum of an external drum imaging device. The web is then cut to form the trailing end of an individual printing plate either before or after the leading end is clamped to the drum. The drum is then rotated such that the plate is wrapped around the drum and the trailing end is clamped to the drum.

Assignee:

Howard A. Fromson - Stonington CT

International Classification:

B01J 2104

US Classification:

Abstract:

A substrate metal such as aluminum, usually in the form of a web, is anodized to form a porous oxide coating. A catalytic metal is then electrolytically deposited into the base of the pores preferably using an AC current. A portion of the oxide coating is then stripped away to expose the deposited catalytic metal at the surface of the remaining oxide layer. Alternately, a generally non-catalytic base metal may first be deposited followed by the deposition of the catalyst metal within the pores over the base metal. Further alternatives include stripping the oxide down to the base metal and then depositing the catalyst metal on the surface, further anodizing to form additional oxide between the deposited metal and the substrate, and enlarging the cross section of the base of the pores prior to the deposition of the metal.

Assignee:

Howard A. Fromson - Stonington CT

International Classification:

B01J 2134

US Classification:

502324, 502439, 427 318

Abstract:

A catalyst structure is formed by forging catalyst support particles from a slurry into the surface of a metal substrate such that the particles protrude from the surface and are permanently fixed into the surface. The forging is accomplished by engaging rollers with the surface as it passes through the slurry to press the particles into the surface. The rollers may be brush rollers, fabric rollers or solid rollers. The particles may be any particles which are capable of having a catalyst deposited thereon and which are hard enough to forge into the metal substrate. The catalyst material is then deposited onto the catalyst support particles.

International Classification:

G03D 1300

US Classification:

219388, 219216, 396575

Abstract:

Certain types of lithographic printing plates are activated by preheating while certain other types are post heated to harden the coating. A platen having a large mass compared to the mass of a printing plate is heated and maintained in the exact temperature range to which the printing plate is to be heated. A printing plate is brought into heat exchange contact with the platen for the period of time required to heat the printing plate to the temperature of the platen. The printing plate may be heated while resting in a fixed position on the platen or while the printing plate is carried over the platen by a continuous thin metal conveyor belt in intimate contact with both the platen and printing plate.

Abstract:

A lithographic printing plate substrate web is brush grained with some of the brushes having the bristles moving over the web along a first track and some additional brushes having the bristles moving over the web along a second track at an angle of at least 5Â to the first track. Some of the brushes may have the axis of rotation perpendicular to the direction of movement of the web in the conventional manner and at least one additional brush having the axis of rotation at an angle to the direction of movement of the web. There may be a plurality of such additional brushes, usually two, with the additional brushes being angled with respect to each other. In one embodiment, the bristles of the additional brush track over the web in a direction perpendicular to the web movement.
