If your printer has noticed dry inks on anilox rollers, you wonder how to get rid of them. You can use Caustic soda, Rejuvenator Gel, and Eliminator Spray. Read on to find out which anilox cleaners suit your printing press’ needs. Before beginning, follow the guidelines below.
When inks on printing presses become dry, they are difficult to remove. Rejuvenator Gel creates a chemical reaction that loosens dry ink. It’s highly concentrated so that it won’t run off rollers. Rejuvenator Gel can be used on various hard surfaces, including anilox rollers, to clean them. Suitable for all types of ink, grease, and oil.
Rejuvenator Gel is available in 20 oz bottles and 5 lb tubs. It works perfectly on anilox rollers, reducing cleaning time significantly. Rejuvenator Gel does not run and is especially useful for cleaning anilox rolls that have dried in heavy ink.
Cleaning your anilox rollers is one of the most important aspects of maintaining the quality of your prints. Even small bits of dried ink can ruin an entire run, resulting in a cost of time and money for a repeat run. Moreover, dirty presses can damage other machinery, and if the rollers are not cleaned properly, new rolls may need to be purchased. Eliminator Spray is a non-abrasive acidic cleaner, which can be applied to ceramic or chrome engraved rollers and condition them for the next print run.
The ink residue 46 is deposited on the bottom 42 of the cell and part of the cell walls. The more ink residues accumulate, the smaller the cell volume is, which affects the ink carrying capacity of the roller. Therefore, a particular cell volume is needed to maintain the desired print characteristic. The printing press must be cleaned and kept free from residue to do this.
Using Caustic soda to remove dry ink on printing press anilox rollers can be an environmentally friendly cleaning method, but it isn’t a good idea for the printing press. Chemical solvents can harm the printing press’s sensitive components and stains on the anilox surface. In addition, caustic soda may be harmful to the print process if the solvent is not diluted correctly.
One alternative to chemical solvents is to use baking soda. However, this substance is highly flammable and toxic, making it a bad option for cleaning anilox rollers. Baking soda is good if the flexo printing press is heavily soiled. In addition to being toxic, caustic soda can cause damage to the parts of the printing press, especially the anilox rollers.
One way to clean your anilox rollers without damaging your print quality is to use a dry ice system. This method is fast, effective, and environmentally friendly. Dry ice works in conjunction with a scheduled cleaning program. This cleaning method is also effective at removing dried-out inks from the rollers. Here are some tips to get the most out of your dry ice cleaning system.
Using solvents to clean anilox rollers can be costly and affect the environment. Solvents released during cleaning can cause air pollution and generate hazardous waste. Increasing solvent use can increase your company’s environmental liability. While cleanliness is crucial for business operations, it must be considered in your overall business strategy. If cleaning is not done responsibly, you risk plugging your roll with dry inks and creating hazardous waste.
