Anilox Technology: Q & A

The six simple solutions every flexographer should know about Apex UltraCell rolls.

1. How does Apex technology make a better anilox roll?

The four critical components of each and every Apex anilox roll that positively differentiate it from all others in today’s tough, real-world conditions are:

• Advanced UltraCell™ cell geometry results in better, more consistent performance on press;
• Exclusive ReleasAll™ high-density non-wetting ceramic results in superior ink release;
• Proprietary UltraMelt™ laser engraving process results in extremely low porosity (less than 1% after engraving);
• Guaranteed UltraShield™ HVOF nickel corrosion barrier that protects against harsh cleaners;

2. Why is UltraCell the best cell geometry for ink transfer?

Simply put, Apex UltraCell and UltraCell Plus cell geometries are wider and shallower than C02 and conventional YAG laser-engraved rolls. Combined with UltraCell’s unrivaled cell precision, our innovations mean:

• Finer line screens without ink upgrades;
• More thorough ink release;
• Precise ink-to-plate transfer; less blade wear.

3. Why is ReleasAll “high-density non-wetting” ceramic better?

Apex perfected a “non-wetting” ceramic composite that repels moisture on the surface of the anilox roll. This “hydrophobic” quality is not a coating that is worn off by doctor blades or aggressive cleaners; it is integral to the ceramic structure resulting in:

• More complete ink release;
• Lower porosity;
• Less ink plugging/clogging;
• Protection against contaminants and cleaners.

4. What is UltraMelt laser technology and why is low porosity better?

In the laser engraving process, Apex employs its own high-output laser which actually melts the ceramic to a glistening surface, making it extremely dense, smooth, and practically non-porous. Anilox porosity is the pressman’s enemy. UltraMelt technology minimizes porosity and maximizes the following:

• Greater resistance to scoring and damage;
• Ability to resolve finer line screens;
• Best ink release.

5. Why is the UltraShield HVOF nickel the best corrosion barrier?

Our nickel buildup base layer is created by a metallurgical process superior to others. Apex’s HVOF (high velocity oxygen fuel) buildup process transforms our build-up layer into an impermeable nickel-walled corrosion barrier that’s twice as thick as the competition’s. Our UltraShield benefits:

• Impermeable barrier to corrosion;
• Resistant to harsh cleaners and water damage;
• Lowest porosity available today (close to 0%).

6. What will an Apex roll mean to me on a day-to-day basis?

Apex is dedicated to making a pressman’s work experience trouble-free. Our four advanced technologies maximize the following:

• Ability to employ finer line screens without ink upgrades;
• Better ink release and less plugging for
• Longer press runs; longer doctor blade life;
• More durable and less prone to damage;
• Faster, easier, and more efficient clean-up.
