Extraordinary Technology

By Dean Miller


Photo polymer Plates: The process is any simple theory, photo polymer properties alter under exposure to UV light. A similar technology exists in your coating on aluminum lithographic making plates, each are exposed for you to UV light through a film (constructive or bad) and in the particular case of 'positive' litho plates your exposed place is washed apart but in the particular case of photo polymer the unexposed material will be washed away even though the exposed section is hardened, consequently film negatives are used.

The particular Process: A film negative is made of your desired image or maybe design so that you can be printed as well as 'letter pressed'. A portion with photo polymer plate can be cut equivalent to the particular image dimension then placed throughout the exposure tray. The actual film negative is overplayed ensuring the film (emulsion side down) can be in good call with no oxygen bubbles or perhaps pockets in between the film and even plate which will result in UV leakage and a blurred picture.

Innovations: Essential developments inside technology have made the polymer plate system more feasible in the latest years at the two entry level and even for large lithographic organizations both enjoying breakthroughs towards a much more 'computer to plate' process. In lithography this different practice using a variation of your photo polymer plate technique known as Flexography that focuses more for accurate halftones necessary by modern presses.

Soaring Demand: With the re surging awareness in letterpress and also particularly the art form side of this particular printing process, photo polymer plates have been in increasing demand in that UK and also in particular plates that allow your deeper impression in to heavy paper for the luxury stationery industry. Even though polymer plates have been offered for a while the KF152 for deep impact work has not yet been distributed in the UK in latest periods.

Conclusion: It may seem to be a little unusual that Europe seems to be at the front with this technologies, one normally considers of Japan or maybe the USA for development but for once legislation may have been a help rather than a hindrance. Europe has increased it's expectations of industry achieving environmental requirements in a way which is forcing advancements in the workplace. Traditional film making uses chemicals which are usually hazardous in use and tough to dispose of, probably this has greater the demand for earlier film products and solutions to increase.
