Printers have many essential parts and pieces that make them highly valuable tools for many industries. However, each material is critical and can affect the printer’s performance; that is why companies like Allison Systems Corporation offer several types of doctor blades, including plastic blades for smoother, easier ink control. Ultimately taking care of the printer is the most important thing that matters in terms of making it last a long time. Plastic materials are usually softer and not as sharp as steel, which makes plastic blades less dangerous when being removed from the press.
There are a few tips you can follow to make sure everything is in working order:
- Follow Manufacturer Guidelines for Proper Maintenance Care
- Make sure Doctor Blades are Clean, Undamaged, and Installed in an Undamaged Chamber
- Select the Proper Chamber, Ensuring it’s the Right Size and Well Maintained
Cleaning your steel or plastic blades and chambers are essential to proper maintenance, but it might be better to replace parts altogether over time. That is why having a reliable resource to find the equipment and parts you need is critical to making sure your printer stays in good working order. Contact Allison Systems Corporation for more information on their products and services.
When it comes to Doctor Blades, knowing which ones suit your printer can make a huge difference in its printing quality. That’s why companies like Allison Systems Corporation provide a vast inventory of sizes and materials so you can find the best end seals for flexo printing. Make sure your flexographic printer gets only the highest quality replacement parts to ensure you get the most from your printer.
Given the unique shape of the flexo printer, getting the right shape and size end seals are essential to ensure everything is working properly. There are ten crucial things to remember about these products:
- When ordering end seals for flexo printing, make sure they are made of a material compatible with the type of ink or coating being used, the length of the run, and the press speed.
- Several new flexo end seals come with coatings and multiple material combinations (two-part and three-part).
- It’s crucial to know that not all felts are created equal.
- Foam end seals are still a top-rated and cost-effective solution.
- Flexo end seal materials can come with different durometers or compression ratios.
- A good seal design for a proper fit is vital to minimize chamber leaking from gaps.
- When installing, make sure your seals are not too tight to cause distortion when put into the chamber.
- The condition of the anilox roll can also play a big role in chamber leaks.
- Doctor blades that are too short or too long can be another source of leaks.
- Many new chambers come with specially molded rubber seals.

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.
