Parts as humble as end seals play an essential role in the printing process. When these parts are not made to exact specifications, leaks result. And these chamber leaks make a big mess, waste ink, and degrade the end product. Starting with a well-made seal from the suitable material and precise measurements are what ensure quality and success.
You’ve experienced the problem with poorly made seals on your press. These include chamber leaks that cause wear and tear on doctor blades, printing quality reduction, and production downtime. However, when these seals are made to order, all of that reverses. Look to Allison Systems Corporation to manufacture custom end seals for your commercial printing presses.
Making Custom Seals for Your Presses
We use state-of-the-art, high-speed CAD equipment during the crucial cutting process. Our process enables us to customize parts and make them with the quality want and in the quantity you need. We don’t die-cut end seals as compression from this process causes the seals to warp, leak, and contain concave edges.
Depending on your needs, we make seals of foam, neoprene, felt, or composite. Talk to one of our team members about the best seals for your operation.
Doctor blades made from steel are known to produce excellent results on high line screen anilox rolls and other difficult metering applications. However, as with all doctor blade materials, steel doctor blades do have some disadvantages. When incorrectly applied, they can produce metal fragments which could lead to anilox scoring. Additionally, operators also have a risk of cut hazards when handling used steel doctor blades if the proper PPE and procedures are not utilized.
Plastic blades can offer a better option than typical carbon steel doctor blades when used with certain applications. Plastic blades work best when metering water based inks on lower line screen anilox rolls typically less than 500 LPI. Plastic blades will provide longer life when compared to carbon steel blades, will not corrode with water based inks, will not release fragments that can cause anilox scoring, and will reduce the potential for cut hazards. Please be aware that worn Plastic blades will present a cut hazard and proper PPE and procedures will still need to be followed when handling them. They are a popular option for corrugated applications and containment blades on chambered inking systems.
There are many choices when it come to materials and edge shapes. Contact us so we can discuss your application to determine if Plastic blades are a good option for your jobs.
Printing professionals spend a lot of time selecting the correct anilox roll cleaner for a job. Close consideration goes into cell geometry, line screen, and cell volume to guarantee that a precise amount of coating or ink is delivered to the substrate. Anilox roll cleaner is essential to maintain this precision.
If roll cleaning is neglected on a regular basis, you will not get the best return on your anilox investment. Plugged cells can adversely affect print quality and cause frustration, waste, and downtime. An anilox roll cleaning program, including daily, weekly, and deep cleaning, will help preserve the integrity of the anilox engraving and maintain quality, press efficiency, and longer anilox life.
When you receive a newly engraved anilox roll from the manufacturer, volume is typically even across and around the surface of the roll. Anilox roll cleaner becomes necessary as the roll is used because a residual amount of ink or coating material is usually left behind in the cells after the transfer has taken place. This residue dries up and creates build-up in the cells. Over time, these dried deposits can greatly decrease the capacity of the cells and reduce their ability to carry and release the precise volume of liquid for which they were designed.
Benefits of Regular Use of Anilox Roll Cleaner:
- The dependable transfer of a precise volume of ink or coating
- Reduced labor and less downtime
- Consistent coverage
- Fewer job rejections and waste
- Longer anilox life and lower re-working costs
A clean press leads to clean and attractive printed products. However, a stained and grimy press can have the exact opposite effect. That’s why it’s crucial to keep your press as clean as possible; it’s the best way to ensure that your clients are completely satisfied.
Fortunately, it’s never been easier to keep your press clean thanks to the high-quality products and press cleaners from Deep Cleen. These products constitute an industrial cleaning solution that has been formulated to remove dried-on ink upon contact from any surfaces that are causing you trouble. Deep Cleen products are effective in glycol, water, and UV ink applications. Press cleaners also available in a concentrated liquid form.
How They Work
It’s easy to use Deep Cleen products. Simply dilute the concentrate in water, apply the solution to any dirty surface, and wipe with a rag. When the stains have disappeared, use water to rinse off the newly-cleaned surface and clear away the solution.
When using Deep Cleen products, always be sure to wear eye and hand protection. Glasses and gloves are the best way to keep you safe during the application process. As with any industrial-strength cleaner; seek medical attention if any products touch your eyes or skin, or if you ingest or inhale any Deep Cleen products.
A composite blade can be used for many ink metering applications. The most common composites are made from fiberglass and carbon fiber. In addition to different materials for the blades themselves, composite blades come in several tip shapes to achieve the utmost performance in ink metering. For composite blades, typically, there is a beveled edge shape with a nominal 10° to 15° bevel angle. Long bevel profiles can help reduce ink leakage past the flexo chamber end seals.
With the use of composite blades from dependable vendors such as Allison Systems, you will experience a result better than any other on the market. In particular, fiberglass and fiberglass plus materials are highly recommended for top quality.
Fiberglass composite blades have a longer life span than carbon steel metal blades with good metering quality. Fiberglass is best used with ceramic anilox rolls with <500 LPI screens.
Fiberglass is usually available in 20 mil thicknesses with an SLR (Seal Relief 15°) bevel.
Fiberglass Plus composite blades typically provide all the features of Fiberglass and improved metering quality, nearly matching that of metal blades. Fiberglass Plus can be used with any ceramic anilox and is usually available in 14 and 20 mil thicknesses with an SLR (Seal Relief 15°) bevel.
It can be easy to forget about your end seals—out of sight, out of mind. However, these small components play a significant role in your ability to retain customers. Without high-quality end seals, your press and doctor blade will run less efficiently and produce inferior results. Both of these consequences can lead to customers looking elsewhere for printing services.
Unfortunately, many printers don’t have sufficient knowledge of these seals to recognize when they’re causing trouble. The best way to make this determination is to contact one of the professionals at Allison Systems Corporation. We have an impressive and in-depth knowledge of end seals and the problems they cause—and we’re always happy to share the benefits of that knowledge with you.
More Common Than You Realize
Many OEMs sell printing presses at extremely high markups. But that doesn’t mean that every component is of the highest quality. Some manufacturers use subpar components (including end seals) to reduce their costs. For this reason, leaky end seals are more common than you might imagine, and they may be the source of your printing frustrations. Excessive ink waste, score lines, long printing times, and damaged rolls are all signs of leaking end seals.
Allison Systems Corporation offers quality end seals to make your press and doctor blade work better than ever before. Count on us for both OEM replacements and custom seals to solve your printing woes.
You might find yourself at a loss when it comes to trying to find effective press cleaners that meet your needs. One to consider is the PlateKote surface agent.

While regular white blades might be the standard, White Plus metal blades stand out from the crowd thanks to their unique properties. Made from a white carbon steel material, these blades feature a precision low-friction metallic coating that is perfect for handling difficult Flexo and Gravure doctoring applications.
The CXP4 blades work their best when they are running chrome gravure cylinders with minimal engraving. This is because the state-of-the-art coating helps to provide lubrication between the cylinder and the blade itself. This reduces issues with hazing and streaking. This impressive coating also provides corrosion resistance when you use it with water-based inks.
Available in 8 mil thickness with a Superhoned Plus bevel, there are many reasons why you can rely on White Plus metal doctor blades when it comes to getting your job done. This is a beveled edge shape with a nominal 2.2-degree bevel angle. This shape allows for the same force control features as the regular Superhoned shape, but with even less tip growth as the blade wears down.
However, it is essential to note that it is not recommended to use them in Flexo containment applications. Contact our business today to inquire about these excellent products.
