| 20080299491 | HIGHLY ALKALINE DEVELOPER COMPOSITION AND METHODS OF USE - A highly alkaline developer composition includes an alkali silicate, an alkyl sulfate, and a water-soluble or water-dispersible polyhydroxy compound such as glycerin. The developer composition is useful for processing imaged elements to produce lithographic printing plates with reduced etching of the aluminum substrates that have been coated with hydrophilic polymers such as poly(vinyl phosphonic acid) and with minimal sludging in the developer tank. | 12-04-2008 |
| 20090042138 | Method of pre-exposing relief image printing plate - The present invention is directed to a method of selectively pre-exposing a photosensitive printing element prior to imagewise exposure in order to remove oxygen from the photosensitive layer prior to imagewise exposure. The invention is usable in a computer-to-plate process to produce flexographic relief image printing elements. | 02-12-2009 |
| 20090214983 | LASER-ENGRAVEABLE FLEXOGRAPHIC PRINTING PLATE PRECURSORS - Laser-engraveable flexographic printing plate precursors have a laser-engraveable elastomeric layer that comprises a non-free radical crosslinked polymeric binder, an infrared radiation absorbing compound, and a compound that remains stable in the precursor but upon imaging thermally degrades to produce gaseous products. The thermally degradable compounds can generate or liberate one or more gases such as nitrogen and carbon dioxide. | 08-27-2009 |
| 20090291394 | Manufacturing method of printing plate using free-seal, free-quantity liquid photopolymer sachet and apparatus using the same - This invention is related to a manufacturing method of a printing plate by using a free-seal, free-quantity liquid photopolymer sachet and an apparatus thereof. Using this technology, the liquid photopolymer sachet is no longer to be limited by quantity with 3 dimensions—width, length and thickness. It is now very free, easy and convenient to use liquid photopolymer resin in a bag to make a printing plate at any width and length with any thickness you want. | 11-26-2009 |
| 20100047718 | METHOD OF TREATING RINSING WASTEWATER FROM DEVELOPING APPARATUS FOR PHOTOSENSITIVE LITHOGRAPHIC PRINTING PLATE, METHOD OF DEVELOPMENT, AND DEVELOPING APPARATUS - An object of the present invention is to provide a simple method for treatment of a washing waste liquid, which enhances the flocculation effect and also enhances filtration characteristics of a flocculated washing waste liquid in a flocculation treatment of a washing waste liquid generated in processing a photosensitive lithographic printing plate. | 02-25-2010 |
| 20110104615 | CURING OF PHOTO-CURABLE PRINTING PLATES WITH FLAT TOPS OR ROUND TOPS BY VARIABLE SPEED EXPOSURE - An apparatus for curing a printing plate made of or having photo-curable material, a method of curing such a printing plate, and a printing plate cured by the method. One embodiment of the method includes curing a printing plate made of or having photo-curable material thereon. The method includes producing light energy on part of the printing plate using a light exposure unit, including relative motion between the light energy and the plate in a transverse direction at a changeable period of repetition, such that curing can produce printing features on the plate that can be switched to have either flat tops or round tops according to the period of repetition. | 05-05-2011 |
| 20120282552 | METHOD FOR OFFSET IMAGING - A method for writing an image to a surface of an offset media ( | 11-08-2012 |
| 20120322008 | DEVELOPMENT OF PRINTING MEMBERS HAVING POST-ANODICALLY TREATED SUBSTRATES - Gum solutions are formulated to protect a negative-working photopolymer imaging layer coated on an anodized aluminum substrate that has undergone a post-anodic sealing treatment with inorganic phosphate and inorganic fluoride, followed by development. In various embodiments, the developer and gum solution have different compositions but contain at least one polycarboxylic acid—which may be a polymer—that beneficially desensitizes the surface after the unexposed photopolymer layer is removed. | 12-20-2012 |
| 20130230808 | DEVELOPER, PROCESS FOR TREATING DEVELOPING SOLUTION, PROCESS FOR PRODUCING PRINTING PLATE, AND FILTER APPARATUS - A process for producing a printing plate, includes feeding a developing solution to an exposed photosensitive resin composition layer; passing the developing solution, in which a photosensitive resin composition is dispersed, through a dispersing-object-filter and flocculating the photosensitive resin composition dispersed in the developing solution by the dispersed-object-filter, and removing a flocculated photosensitive resin composition from the developing solution passed through the dispersing-object-filter. | 09-05-2013 |
| 20150086928 | METHOD OF MANUFACTURING A FLEXOGRAPHIC PRINTING PLATE WITH SUPPORT STRUCTURES - A method of manufacturing a flexographic printing plate includes designing a patterned design that includes a plurality of lines and a plurality of support structures and laser-ablating the patterned design into a thermal imaging layer. A support structure of the plurality of support structures is disposed at an offset relative to a line of the plurality of lines. | 03-26-2015 |
