Cleaning Your Anilox Rolls the Right Way

Keeping your anilox rolls clean is essential in ensuring that your flexographic system works the way it’s supposed to. When anilox rolls get “dirty,” it’s due to a buildup of ink from past printing sessions. Ink can dry in the cells of the anilox rolls and cause serious problems for future prints. Thankfully, ink buildup can be easily remedied (and prevented from happening altogether), through proper and regular anilox roll cleaning.

For many business owners, however, anilox roll cleaning appears at face value to be anything but easy. Anilox rolls themselves are not only incredibly important to the flexography printing process — they’re also very fragile and quite expensive to replace. Together, these characteristics make anilox rolls fairly intimidating to clean. Fortunately, our flexography cleaning professionals here at Flexo Wash are here to help. In this article, we’ve put together a short guide on how to clean your anilox rolls the right way. We’ve also provided a wealth of information on our industry-leading anilox roll washing machines, designed for both wide and narrow web products and used by some of the world’s top printing companies.

Do My Anilox Rolls Need to Be Cleaned?

After each printing, a trace amount of ink is left on an anilox roll. This ink can collect in cells or other surface areas of the roll and can eventually lead to cell plugging, which will directly affect printing quality. When your anilox roll color density or coat weight diminishes, that’s a telltale sign that your nilox roll needs to be cleaned. Another way to find out if your anilox roll needs to be cleaned is by using a Capatch Test Strip to determine your roll volume. If the volume is plugged 50% or more, then it is time to clean your roll.

Flexography Ink Cleaning: What To Avoid

There are several dos and don’ts to pay attention to when cleaning your anilox rolls. Firstly, it is important to use safe and non-corrosive cleaners with a pH value between 6.5 and 10.5. Do not use 100% acidic, ammonia, or chlorine as cleaning liquids. If you’re using a journal system, be sure to handle your anilox rolls with great care. We recommend keeping protective covers on your rolls when storing them as well. If you are using anilox roll sleeves for your flexography printing, we recommend thorough rinsing after each use, and regular cleaning with the use of approved cleaning chemicals. (Stay away from harsh chemicals such as oven cleaners or other cleaners not specifically developed for cleaning sleeves.)

Anilox Roll Cleaning Methods

While chemical cleaning is the most common form of anilox roll cleaning, there are several other methods that may also be used for more intensive cleans. These methods include:

  • Ultrosonic Cleaning: Ultrasonic cleaning uses high-frequency sound waves sent through water or another solvent to break down ink or other unwanted deposits on an anilox roll.
  • Baking Soda Blasting: This relatively new anilox roll cleaning method air-blasts fine, uniformly-sized baking soda particles at the surface of a rotating roll. The baking soda particles are smaller than the anilox roll’s cell openings and effectively reach in to break down any offending material. A vacuum is then used to remove the baking soda and unwanted material, leaving the roll clean.
  • Plastic (Poly) Bead Systems: Plastic (poly) bead systems work in the same way that bake soda blasting does, except they make use of tiny plastic beads to clear out unwanted ink and debris inside an anilox roll’s cells.

The Importance of Regularly Cleaning and Maintaining Your Flexography Equipment

If you work with flexography printing systems, you know that nearly every piece of flexography equipment at your company comes into contact with ink and gets “dirty.” From the anilox rolls and doctor blades to the flexo plates and the ink trays themselves, almost nothing is exempt from this phenomenon. Over time, ink buildup and other sources of contamination can begin to have direct impacts on your printed products, thus costing you time and money and negatively affecting your bottom line. Components of your flexography printing system may also stop working for a variety of mechanical reason if regular inspections and maintenance appointments are not scheduled. To ensure that you don’t have a component breakdown in the middle of the work week, it is imperative that you stay on top of regular maintenance. In this short article, our flexopgraphy cleaning professionals here at Flexo Wash have compiled several reasons why regularly cleaning and maintaining your flexography equipment is the right move for your business. We’ll also give you some information on our very own line of specialized flexography cleaning machines. Read on and contact our team at (888) 493-5396 today!

Keeping Everything Running Smoothly

In the flexography printing business, efficiency and quality are everything. You want to be able complete a wide range of printing jobs as quickly as possible, and you also want each and every one of those jobs to meet the expectations of your clients. For these reasons, having properly-functioning equipment day in and day out is vital to your business. A dirty anilox roll can lead to unsatisfactory ink distribution, which will in turn lead to compromised detail and image rendering on final products. Cracked or dirty plates won’t be able to transfer ink as effectively to the substrate, leading to similar quality diminishments on final products.

These problems are bad enough in and of themselves, but when they happen in the middle of a workday, production halts and bottom lines plummet. Thankfully, such issues can be avoided through regular cleaning and maintenance. Keeping your anilox rolls, flexo plates, doctor blades, and ink trays clean at all times will greatly reduce the likelihood that your finished prints will turn out poorly. Plus, regular cleaning will help save you time in the long run. By scheduling regular maintenance inspections for your equipment, you will be able to identify problems before they arise and schedule necessary repairs or replacement wherever needed without losing a day (or more) of work and compromising your bottom line. Maintenance inspections will also alert you to any practices you may have been neglecting or performing incorrectly, helping you to avoid costly mistakes in the future.

Keeping Costs Low

As a business owner, you want to keep costs low. For this reason, regular cleanings and maintenance inspections might seem like a bothersome or unnecessary investment. In fact, this couldn’t be further from the truth. By scheduling regular maintenance inspections, you are protecting yourself from unwanted equipment mishaps and malfunctions down the road. Should a component of your machine break in middle of a busy printing day, you will not only be out the cost of a new component — you’ll have also lost at least a day’s worth of business. By scheduling regular maintenance inspections, you will know to repair and replace parts ahead of time, keeping your bottom line and your peace of mind intact.

Regularly cleaning your flexography equipment will also help keep costs low. Regular cleanings will extend the lifespans of nearly all components of a flexography system, thus saving you money on untimely replacements.

The Best Techniques for Keeping You Anilox Rolls Clean

Your anilox rolls are a vital component of your flexography printing business. Anilox rolls control just how much ink is distributed onto printing plates, which then transfer the final image to a substrate. When anilox rolls fail to work correctly, it is impossible to get a properly-rendered finished product. Plus, an anilox roll that is not well cared for may need to be replaced, costing your company several hundreds to thousands of dollars. One way to keep your anilox rolls working better for longer is to keep them clean. Cleaning anilox rolls may seem intimidating; after all, they’re expensive, fragile, and vital to your printing process — small mistakes can be costly. To help you out, we’ve compiled this short guide on the dos and don’ts of anilox roll cleaning. Below, you’ll get advice from our experts on anilox roll cleaning frequency, best practices, and other maintenance considerations. We’ll also give you the opportunity to explore our efficient and highly-effective anilox roll cleaning machines, designed and manufactured to clean anilox rolls for both narrow and wide web products. Read on for The Best Techniques for Keeping Your Anilox Rolls Clean, and contact our flexography professionals at (888) 493-5396 today!

Knowing When to Clean

Perhaps the most frequent question we get regarding anilox roll cleaning is “How often should I clean my anilox rolls?” The answer is: it varies. While there’s really no such thing as too much cleaning (provided you’re doing it properly), some companies may need to clean their anilox rolls less frequently than others. Cleaning frequency is highly dependent on the volume of work your anilox rolls take on. An anilox roll that comes into contact with a lower amount of ink per day will need to be cleaned less frequently than an anilox roll that comes into a higher amount of ink per day.

Cleaning frequency also partially comes down to preference. Some businesses prefer to clean their anilox rolls quite frequently, which keeps the cleaning time per session relatively short. Other businesses may wait longer in favor of a more intensive clean with less frequently. Whichever you choose, be sure not to wait too long: excessively dirty rolls will not only damage your finished products — they may also sustain long-term damage themselves.

At Flexo Wash, we recommend cleaning your anilox rolls after every printing session. However, our specially-designed anilox roll cleaning machines are capable of providing thorough cleans to anilox rolls that haven’t been cleaned in much longer time spans. Provided your rolls aren’t dirty enough to affect your product, you may have to clean them weekly or even monthly, especially with automated systems like our anilox roll cleaning machines.

Using the Right Cleaners

At the heart of anilox roll-cleaning best practices are proper cleaning products. When cleaning your anilox rolls, it is important to use safe and non-corrosive cleaners with a pH value between 6.5 and 10.5. Do not use 100% acidic, ammonia, or chlorine as cleaning liquids. Aside from common chemical cleaners, there are several other anilox roll cleaning methods, including baking soda cleaners, plastic (poly) bead systems, and ultrasonic techniques, each with their own unique advantages and drawbacks. At Flexo Wash, we highly recommend using our anilox roll cleaning machines, which use specialized cleaning solutions, powered washing techniques, and directed air drying to effectively and efficiently clean anilox rolls of all kinds. You can learn more about our machines in the final section of this article.

Other Considerations

Before moving on to the final section of our article, we’d like to remind you of several general care and maintenance tips that will help your anilox rolls safe and clean. Firstly, proper handling of rolls is essential. Try not to touch the rolls’ ceramic with your hands; instead, handle them by their ends. We recommend using protective sleeves to keep rolls safe at all times. We also recommend storing your rolls in a two-arm rack with a half-inch clearance on each side of the roll. This system allows the majority of the weight to rest on the thicker part of the journal rather than the ends of the journal.

The Importance of Anilox Roll Cleaning

If you work at a printing company, you know how important an anilox roll is to the flexographic printing process. Indeed, anilox rolls are the distinguishing feature of flexography and give it the ability to effectively and efficiently print a wide range of finished products. If you work in printing, you also probably know how expensive anilox rolls are (most run in the several hundred to thousand-dollar price range for an individual rolls). The last important thing you likely know about anilox rolls is their inherent fragility. On their surfaces, anilox rolls are coated in  hard, easily-cracked ceramic material will thousands of small indentations (called “cells”) responsible for precisely distributing ink onto a flexo plate. Even the lightest improper contact with anilox roll can chip or crack its surface, thus rendering it incapable of performing its essential function. For all the above reasons, you may also know just how important it is to properly maintain an anilox roll — but for same reasons, you may be afraid to do it.

In this article, our experts at Flexo Wash are here to remind you of the importance of anilox roll cleaning, give you tips on when to do it, and provide you with an easy, mechanized solution to help take the stress out of anilox roll cleaning. Dirty rolls can impact printing your printing business in a number of ways. For one, rolls with dried or caked-on ink will not perform to the same level of detail as clean rolls. They also take longer to do the same jobs. This is because dried-on ink prevents new ink from being properly transferred to printing plates (and subsequently to the substrates themselves). Put simply, dirty anilox rolls lead to lower bottom lines for printing companies. If you’re industry, you know this is a setback you simply can’t afford.

Cleaning Frequency

Many printing companies have asked us how often they should be cleaning their anilox rolls. Our answer is always the same: it varies. There are several factors that contribute to anilox dirtiness, and each of these factors occurs to varying degrees in varying commercial settings. If you your anilox takes on a relatively light workload with lower ink levels, you may not need to clean as often as another company’s anilox that is worked harder on a day-to-day basis. Another factor involved in anilox cleaning is that of preference. Would you rather clean regularly in shorter cleaning sessions, or less regularly in longer, more intensive cleaning sessions? The choice is up to you — but remember, don’t wait too long. If anilox rolls get too dirty, they’ll ruin your product.

At Flexo Wash, our professionals recommend washing anilox rolls after each and every print job. That being said, our specialized anilox washing machines can enable lighter-load companies to wash their anilox rolls as infrequently as once a month. With anilox roll cleaning, it really depends on usage. The more you use your roll, the more often it will need cleaning.

Signs That Your Anilox Roll Needs Cleaning

The biggest contributor to anilox roll dirtiness is dried ink. After each printing, a trace amount of ink is left on an anilox roll. This ink can collect in cells or other surface areas of the roll and can eventually lead to cell plugging, which will directly affect printing quality. You can tell that your roll needs cleaning when your color density or your coat weight diminishes. Another way to find out if your anilox roll needs to be cleaned is by using a Capatch Test Strip to determine your roll volume. If the volume is plugged 50% or more, then it is time to clean your roll.
