What is photopolymer printing plates?
Photopolymer is photosensitive material in sheet form that is exposed to UV lights through a negative film. The light shines through the clear sections of the film and hardens the polymer. The plate is washed out with water. The exposed areas are left to form the relief and the unexposed is washed away.
How is photopolymer resin made?
Photopolymers are imaging compositions based on polymers/oligomers/monomers which can be selectively polymerized and/or crosslinked upon image-wise exposure by light radiation such as ultra-violet light. For final use, they are made into different forms including film/sheet, liquid, solution etc.
What is liquid photopolymer resin?
One of two types of photopolymer plates used in flexography, in contrast to a sheet photopolymer. The liquid photopolymer is enhanced by exposing the base side of the plate to ultraviolet light, hardening the photopolymer on the reverse side of the plate. …
What is photopolymer plate made of?
Photopolymer printing forms for pad printing were originally developed from letterpress and flexographic printing forms. They are made of a laminate of steel base on which plastic UV photosensitive polymer material is anchored by an adhesive layer (Figure 16.6).
What are the disadvantages of flexography?
On the downside, flexographic printing is not very advanced. It cannot produce complicated and extensive artwork as compared to that produced by rotogravure printing. The colors in the final product of flexographic printing are neither as bold nor as crisp as they are in rotogravure printing.
What is a flexographic plate?
Flexographic plates, like letterpress plates, are relief plates with image elements raised above open areas. They are elastomeric in nature in contrast with hard letterpress plates. They are used in rotary presses and with low viscosity inks.
What is photopolymer in 3D printing?
Photopolymerization is the curing process that’s characterized by the use of ultraviolet (UV) light. In 3D printing, it’s used to cure the deposited material. When exposed to UV light, the deposited material cures. Rather, this curing process is used exclusively for photopolymer materials.
Is acrylic a photopolymer?
Because of a higher raw material cost and the additional time to process and finish the material, photopolymer signs are more expensive than a comparable acrylic sign. Photopolymer could be used in all applications, especially where a more durable product is desired and where vandalism of the signs is a factor.
Who invented photopolymer?
Louis Minsk et
The first synthetic photopolymer for imaging applications was patented (US Patent 2,610,120) by Louis Minsk et al of Eastman Kodak in 1952. The invention was entitled “Photosensitization of Polymeric Cinnamic Acid Esters”. The photopolymer was essentially a photoresist based on polyvinyl cinnamate.
How does a computer to plate printing system work?
Computer to plate printing systems, as they apply to pad printing, enable the user to take a digital graphic file and by means of a laser, make high-quality steel and polymer pad printing plates (clichés) designed to be laser engraved without the use of film, exposure systems, or chemicals.
What makes a platecrafter different from a printer?
Specialists, such as PlateCrafters are able to take advantage of all 3 phases of the latest plate technologies. PlateCrafters is able to focus on producing the best plate, so that the printer can focus on producing the best end product. PlateCrafters serves all industries and provides multiple varieties of photopolymer.
How is photopolymer used in flexographic printing process?
Photopolymer replaced natural and synthetic rubber as the material of choice in flexographic printing decades ago. Technologies for producing photopolymer have been advancing ever since. These technologies are mainly centered around a polymer’s ability to release ink smoothly and hold finer screens to create more detail on the end product.
How is an image reproduced on a printing plate?
This leads to a decrease of the imaging time needed to expose a whole printing plate. The image is reproduced line by line on a fixed flat printing plate by a laser beam that is deflected by a rotating polygon mirror and then onto the printing plate.
