Jet Photopolymer Plate Maker ** Runs on 240v power ** This is a complete photopolymer plate maker, developing water based photopolymer plates for printing. Photopolymer jetting (commonly known as PolyJet technology) developed by Israel-based company “Objet Geometries Ltd.,” was later merged with “Stratasys” (a well-known leading manufacturer of 3D printers) in 2012. The terpene can then be removed by distillation (either steam or vacuum) and the non-solvent can be reclaimed by filtering or screening-out the flocculated uncured photopolymer. Inkcups offers six different types of photopolymer plates for pad printing. Helfen Sie globalen Kunden einfach Photopolymerplatte Machen Ausrüstungen zu beziehen. This solvent mixture could then be distilled to remove the n-butanol (because of the wide difference in boiling points between n-butanol and the d-limonene/2(2-butoxyethoxy)ethanol mixture) leaving the clean d-limonene/2(2-butoxyethoxy) ethanol solvent for reuse in processing more photopolymer plates. Both plates had image relief of 30 to 35 mils. Water rinsing is not practical when conventional hydrocarbon or chlorinated hydrocarbon solvents are used because of the rinse water will become contaminated with the toxic synthetic solvent; additionally, such solvents are also are insoluble in water. The film has a natural curl – work with the film curl side uppermost. USE OF BENZYL ALCOHOL AS A NON-SOLVENT. Photopolymer plates based on a terpolymer of butadiene, acrylonitrile, and acrylic acid were processed as in Example 1 with this solvent. First photopolymer flexo plates were made from liquid photopolymers introduced by Asahi in 1972. Such a water emulsion, with many plates, produces less swell of the photopolymerized or cross-linked photopolymer image and permits water rinsing of the emulsion from the plate prior to drying the plate at elevated temperature in a drying oven. These solvents may be used by themselves or in a mixture with a "non-solvent" (i.e. A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. This composition, which has use as a flexographic printing plate, requires processing by a tetrachloroethylene solvent in blends of tetrachloroethylene and a non solvent. 0430233 - EP90122838B1 - EPO Application Nov 29, 1990 - Publication Apr 22, 1998 Katsumasa Yamamoto Kyoichi Mizuno Kosaku Onodera Keizo Kawahara Masaru Nanpei.

Halogen desk lamp (50 watt); Long (and hot) exposure, the light I've used takes 7 minutes and gets very warm in that time. 4. Open the lid of the exposure unit and li up the glass platen. This invention relates to the use of terpene class, natural product and blended solvents in flexographic photopolymer printing plates. In 1960, DuPont came out with acrylic-based Dycril followed by Nyloprint by BASF in 1968. Polymer plates for non-letterpress uses: while our troubleshooting only extends to using photopolymer plates for letterpress printing, there are hundreds of other uses for photopolymer. Photopolymer hardens out under the influence of UV-light (Ultra-violet). Photopolymer plates based on a terpolymer of butadiene, acrylonitrile and acrylic acid were processed as in Example 1 with this solvent. tetrachloroethylene and n-butanol. Again the plate quality was superior to that obtained with perchloroethylene under equivalent conditions. The plate was then exposed through a Flex-Light® four step test negative. 0,3mm thick (only a support), the photopolymer layer (appr. Ordinarily, this is accomplished by washing the exposed plate in a solvent which can remove the unpolymerized material while leaving the polymerized (cured) material intact. Again the plate quality was superior to that obtained with perchloroethylene under equivalent conditions. It is important to remove the wash out solvent from the plate prior to drying because any solvent retained on the plate after processing will increase plate swelling and distortion upon oven drying. The total processing capacity of this solution was also greater than that of the perchloroethylene - butanol mixture. Similarly, British No. An additional feature of the terpene-based solvents is the ability of terpenes to form emulsions with water. 350057 5" x 7" discontinued, we suggest KM Photopolymer plates as a replacement.

Plate exposure times equivalent to those required for perchloroethylene-butanol washed plates were necessary to hold 0.004" lines and 3%, 150 line half tones with this wash solvent. Plate exposure times equivalent to those required for perchloroethylene-n-butanol washed plates were necessary to hold 0.004" lines and 3%, 150 line half tones with this wash solvent. Dimensions: 100 x 200 mm. With the d-limonene emulsion, a straight 4 mil line and a satisfactory 3%, 150 line half tone was produced by the four minute exposure. The process is clean, easy and safe to use. We’re a greener alternative! This is why most printers opt to procure their photopolymer printing plates from trade shops. After wash out the plate was rinsed with fresh solution, and subsequently rinsed with water using a standard kitchen sink spray hose. At this point, a third 12"×15"×0.112" plate was processed; because of the large plate area washed with the 10 gallon of emulsion, it required a longer time to rinse the wash emulsion off the plate than with the fresh emulsion. This superior plate quality at a shorter exposure time was a direct result of the reduced swelling in the plate produced by the terpene emulsion compared to the swelling produced by the conventional 75/25 perchloroethylene/butanol wash solution. developing and washing photopolymer plates and forms in an enclosed unit. Mimicking photopolymer developing machines, we place a sheet of rubber onto a hard, flat surface, on top of which the photopolymer is fixed. Stop developing by rinsing well with water. 28 liters 25% (by weight) aqueous potassium toluene sulfonate, 5 Kg OT-100 (dioctyl sodium sulfosuccinate). The plate was subsequently washed in the wash unit with the above formulated solution for four minutes. The exposure steps were 4, 6, 8 and 10 minutes. y�˹�[��͙>7.���� 2. Again, when processed by this solvent, the plate quality at low exposure times was equivalent to that obtained with perchloroethylene-butanol at higher times. This allowed extended use of the solution because the spontaneous polymer separation prevented a build up of photopolymer, permitting continued use of the solution; up to approximately 200-300 square feet of plate area could be processed without distillation. This permits repeated use of the solvent without the need for distillation to remove uncured photopolymer. Again the plate quality was superior to that obtained with perchloroethylene under the same conditions. Photopolymer plates based on a block copolymer of styrene and isoprene were again processed as in Example 1 with this solvent. This composition has use as a flexographic printing plate and requires processing organic solvents including methyl ethyl ketone, benzene, toluene, xylene, trichloroethane, trichlorethylene, methyl chloroform, tetrachloroethylene, or solvent/non-solvent mixtures e.g. Minimise skin contact with fixers and plate developers. Photopolymer film on aluminium plates. To the best of our belief Our Identity is satisfactory rates; prompt services & Accelerated In our work, although we don’t compromise with quality. Other studios have been using photopolymer plates and exposing screens for years. endstream endobj 88 0 obj <. Because of the greater solvating power of the 100% solvent there was a problem with plate swelling and loss of plate detail. What isn’t exposed because it’s blocked by the black part of the film negative … Brushing or agitation can be used to facilitate the removal of the non-polymerized portion of composition. The plate surface is the only area that comes into contact with the substrate after the ink is applied to the plate. A change in any of these variables affect the end product. Plates are here!
