Special Surface Coating Eliminates Over-Impression Errors

 

This unique patented coating is applied directly onto your existing or newly-manufactured cylinder, providing a vibration-absorbing platform for the plate that allows for over-impression and virtually eliminates banding. Vibration is created by a combination of shafts turning, gears meshing, plates contacting anilox rolls, variation in cylinder TIR and the shuddering created by the die-cut station along the frame of the press. This coating acts as a shock absorber and allows the press operator to over-impress the plate to the substrate without the usual negative consequences.

 

Performance Enhancing Cylinders are compatible with all flexo solvents and inks and are designed to resist damage from cutting. All cylinders are spin-balanced after coating is applied.

He was actually at one of the early trials and personally set the impression for it!

 

Key Advantages:

* Mount plates directly to the cylinder with 0.005” tape

* Greatly reduces, or in most cases removes, banding or gear marking

* Allows operator to increase press speed and decrease make ready time

* Eliminates flexo “doughnut” dots, which significantly increases tonal range

* Reduces dot gain, slur, and holds tiny reverses open and clean

* Improves consistency across press runs due to the lack of cushion breakdown

* Extends the life of digital plates

Ordering Options:

 

Option 1: Place your order for a new base cylinder with us. We will order it from Rotometrics and have it coated and shipped to you.  Qualifies for pre- machined discount.

 

Option 2: If you have the ability to change gears, send in a small cylinder to which the coating will be applied, converting it to a larger size. This option qualifies for a pre-machined discount.

 

Option 3:  You may also choose to send in a cylinder where you do not want the size converted. We will have Nu Tech machine it down and apply the coating. This method does not qualify for a pre-machined discount.

 

We will be more than happy to discuss these options with you in more detail when you call to place your order.

Frank Burgos says:
When I first heard the claims made by the folks at Nu Tech regarding Performance Enhancing Cylinders, I was extremely skeptical. In fact, Jim Wyman, of Nu Tech, reminds me that I didn’t even give him the “time of day” the first time he approached me with the concept.

 

For some reason, despite my skepticism, the second time he approached me, I agreed to evaluate the cylinders. However, I told him that we would have to do some serious testing before I put my company’s reputation on the line.

 

We were able to arrange for a test trial at North Carolina A&T State University, with the help of Dr. Dean Gilbert, and several industry folks, including the folks at Flint Group, who were very generous in helping design a plate that we thought was sure to fail and providing plenty of them for testing, and Water Ink Technologies, who provided the ink. I believe Avery Dennison provided the substrate, and I apologize to anyone I may have left out. (See the December 07 FLEXO Magazine article “Banding Be Gone”? (www.flexomag.com)

 

Several operators, lab technicians, and other industry folk have either set impression themselves, or were present when others did. I personally set impression multiple times, and the last time I visited the university, they had made over 120 sets of samples. A set is printing with a conventional cylinder-tape-plate configuration at 150 fpm, then at 250 fpm, then immediately printing a with PEC cylinder-tape-plate combination, also at 150 fpm and 250 fpm.

 

I am here to tell you that I was absolutely amazed, as were all of my colleagues. Side-by-side comparisons leave no doubt; these things work!

 

Since then, we have agreed to work with Nu Tech, and I’ve been telling anyone who will listen about these cylinders. They absolutely reduce or eliminate banding in vignettes, process, and other half-tone images. I am very excited about offering these cylinders to the market as another tool we can use to help in the battle to get closer to the quality achieved by our competing technologies, litho and gravure. I have a feeling they’re gonna get nervous!

NEW: Eliminate Banding on Thin, Unsupported Films with PEC HD Coating

 

Johnson City, TN June 10, 2008 - The patented PEC HD, like the standard PEC coating, eliminates two major variables in the Flexographic printing process: the removal of cushion sticky back tape, and impression setting of the plate to the substrate. The company’s unique polymers are applied in .375-in. thickness to the radius of a newly manufactured or existing plate cylinder.

 

The print results achieved with the PED HD substantially diminish or remove the frequency and amplitude of banding or gear marking on Narrow and Mid Web Flexographic presses, while reducing waste, increasing yields, and providing predictable, high quality print on unsupported thin films and other high hold out substrates.

 

“We have addressed the same printing issues with the PEC HD on thin films, which our standard PEC product solves for the pressure sensitive market” says Jim Wyman, Managing Partner of Nu Tech Coatings. Narrow Web, in-line Flexo printers face distinctive challenges when printing on thin, unsupported films. The PEC HD levels the quality bar for Flexo printers to compete with offset and gravure printers for a share in the growing market for shrink sleeves.

 


 

Cleaning & Coating a Nu Tech Performance Enhancing Cylinder (PEC)

 

Materials Needed:

Odorless Mineral Spirits

Alcohol or Acetate

Behr Water-Based Polyurethane Clear Matte Finish No. 780

Lint-Free Rag

Scotch-Brite Pad

 

 

Cleaning Residual Adhesive:

 

To remove the residual adhesive left on the surface of the PEC from the mounting tape, wet a rag with mineral spirits and wipe it over the surface of the cylinder. Let the solvent sit for a few minutes and wipe it off with a lint-free rag or a Scotch-Brite pad. The adhesive will loosen and come off, leaving an oily feel on the cylinder.To remove the remaining mineral spirits, which is the source of the oily feel, wipe down the cylinder with alcohol or acetate. Make sure that all solvent has flashed off the surface of the cylinder. Residual solvent will prevent tape from adhering to the cylinder.Note: Over time, the coating on your PEC will begin to wear off and will need to be reapplied. You will see a color change in the surface of the PEC that will indicate the coating is wearing off.

 

Coating with Behr Primer:

Coating your cylinder with Behr Primer is an option which will allow for easier removal of the tape from the cylinder. It is an alternative procedure to use if you have been unable to find a 0.005” mounting tape that is easy to remove.

  1. Make sure the surface of the PEC is clean and dry.
  2. Saturate a clean rag with the Behr Primer and wipe the face of the PEC.
  3. Add primer to the rag as needed and make sure to get complete coverage.
  4. Wipe off any excess primer and allow two hours drying time before applying tape.
