Looking to stop the excess costs from issues like plate lift, mounting problems, or ink incompatibility when printing? Try an elastomer blend sleeve for your flexographic printing needs.
Blends of elastomer, which can include both natural or synthetic polymers, are used in flexo printing because they are
Elastomer sleeves eliminate a variety of problems associated with plates, such as lift, registration issues, and poor ink transfer. They are ideal in applications where a thousandth of an inch is the difference between success and failure.
Better sleeves means better prints, which equals continued sales -- and more revenue.
Here are four examples of elastomer blends -- available in varied durometers and surface tensions -- and their effective flexographic printing uses:
Elastomer blends are used to produce products with a variety of enhanced characteristics that are significant in printing. These can include things like:
These characteristics are obtained by careful choice, and mixing of several different components that make up the final composite material. These include:
The choice of all of these components, along with precisely controlled vulcanization (heat and pressure treating) determine the final characteristics of the material. These can be selected to produce a sleeve with various features such as highest quality imaging, unmatched longevity, and superior ink transfer.
Laser engraving of elastomer printing plates and cylinders has been a popular industry practice since it was first introduced to the United States, by Luminite Products in the 1970s. At the time, the quality and longevity of elastomer sleeves made them an attractive alternative to plates mounted directly on cylinders, which were inconvenient to change out and often short-lived
Advances in both elastomer and laser technology have since kept laser-engraved image carriers at the forefront of quality and efficiency in printing.
Elastomer blend flexo print sleeves:
When combined with air assist mounting sleeves they allow for almost continuous press operation for maximum ongoing profitability.
We've talked about the technical side of elastomer blend sleeves and how they can improve both your print quality and your efficiency, but another benefit just as important is their environmental-friendliness.
Elastomer sleeves, are two to three times more durable than photopolymer plates, and often exhibit a resistance to harsh chemicals. This means by using one elastomer sleeve, you're effectively reducing the waste from three photopolymer plates. That's a big difference.
Plus, elastomer blend sleeves are easier to store and care for, and do not require the use of as many harmful chemicals as other flexo printing methods.
When it comes to sleeves, cylinders, and plates, material choices directly impact the quality of your flexographic print jobs.
Elastomer blends allow you a wide array of options for your printing needs, including:
