The Disposable Liquid Volume Tester for Anilox Rolls, Full Coating Gravure Rolls and Tri-Helical Rolls

Capatch is a use-one-time tool that works by contact with the roll as a kind of sticker. A calibrated amount of indicator fluid contained within a capsule on the sticker is forced across the roll under the Capatch sticker when the user runs across the surface with a blade, known as the doctor blade. The blob of indicator fluid breaks through the front of the capsule and is pushed into the open cells of the roll by the doctor blade. The liquid blob first fills the cells nearest the capsule, decreasing in volume as it is pushed forward, until the entire volume of the blob has vanished into the roll cells. The length of the liquid track determines the current volume of the open cells of the roll. Since the volume of the indicator fluid is constant in all Capatch strips, the length of the track is inversely proportional to the ink, adhesive or coating volume of the roll cells.

Five   easy to use Capatch© units are now available:

Units of BCM/sq inch are used in America while CC/m2 are used throughout the rest of the world

The strips have different scales or adhesive strength:

Low volume 2 to 7 cc/m2 and 1.25 to 5 BCM/inch2 (green – orange strip).
Often used in label printing industry.

 Medium volume 5 to 25 cc/m2 and 3 to 15 BCM/inch2 (dark blue – orange strip).

Often used for rolls with maximum 120 lines.
Often used in corrugated industry.

 Medium volume 5 to 25 cc/m2 and 3 to 15 BCM/inch2 (light blue – orange strip).

Often used for rolls with 120 lines or more.

Often used in flexible packaging and label printing industry.

 High volume 15 to 70 cc/m2 and 10 to 50 BCM/inch2 (red – orange strip).
Often used for rolls to apply adhesives, coating, varnish and similar.

Tri-helical volume 4 to 70 cc/m2 and 2 to 50 BCM/inch2 (brown – orange strip).

Used for tri-helical rolls.

Compare the results of the test to the roll manufacturer’s bcm. This will tell you how effectively the roll is performing and should maintenance or cleaning be required.

Stop Production LossesIn the printing industry, regular testing of the volume of your anilox rolls is crucial to prevent production losses, wear, “doctoring”, improper cleaning or a manufacturer fault can result in an incorrect volume. Don’t assume that any roll has the correct volume.

Use Capatch© To:

  •          Test the volume of your anilox roll.
  •          Reduce production downtime.
  •          Prevent scrap production.
  •          Schedule roll cleaning.

Customers

We distinguish the following categories of customers:

Flexo printers and coaters The flexo printers and coaters will be the largest client category.  Flexo printers frequently clean their anilox rolls and may like to verify that the roll is clean and has the correct volume by using the Capatch before and after cleaning. Not every cleaning system is capable of penetrating the fine line screens encountered on laser engraved anilox rollers. The printer needs to know how far the cleaning process has restored the cells to their original capacity after each cycle. The printer may also be interested to check the volumes on rolls that have been cleaned by third parties.

 

 

.

Offset printers  Offset machines might have a (final) station with an Anilox, Tri-Helical or Gravure Full Coating Roll for laminating, coating or varnishing. It is difficult to determine whether the cells are polluted with transparent and invisible residues.

Printers with gravure rolls for full coating  The volume of gravure rolls for full coating can also be checked by the Capatch. It is not possible to use the Capatch for gravure rolls with an engraved design. Some printers use Capatch more frequently. In chapter “product” you can read more about application frequency.

 

 

Roll cleaners   A part of the cleaning of rollers is outsourced to specialized roll cleaning companies. These companies need to assess the quality and effectiveness of their service. These companies can demonstrate to their clients the results of their services by using the Capatch before and after cleaning the anilox roll.

Suppliers of inks, coatings and adhesives These suppliers use the Capatch for troubleshooting. It is not always clear whether poor roll performance is the result of improper roll volumes or incorrect ink, coating or adhesive. The sales representatives spend a part of their time communicating with technical support for troubleshooting. These suppliers confirm that in several cases the problems turned out to be roll insufficiency when they are called to help a printer who assumed that the ink, coating or adhesive was faulty.

Printing press manufacturers and suppliers  Manufacturers use Capatch for troubleshooting.

 

stop production losses:

In the printing industry, regularly testing the volume of your anilox roll is crucial for preventing production losses. Wear, 'doctoring', improper cleaning or manufacturers' faults can cause incorrect volumes. Don't assume that your roll has

the correct volume. Use Capatch to:

-       Test the volume of your anilox roll

-       Reduce production stops to five minutes or less

-       Prevent scrap production

-       Provide a verification of the volume of an anilox roll after cleaning or maintenance.

How it works:

Capatch is a one-time-use tool that works by contact with the anilox roll as a kind of sticker. A calibrated volume of indicator fluid contained within a capsule on the sticker is forced across the anilox roll under the Capatch sticker by running across the

surface with a blade, known as the doctor blade. The blob of indicator fluid is forced out of the capsule and is pushed into the open cells of the anilox roll by the doctor blade.The liquid blob first fills the cells nearest the capsule, decreasing in volume

as it is pushed forward, until the entire volume of the blob has gone into the cells. The length of the liquid track is inverselyproportional to the current volume of the open cells of the anilox roll.

 

A scale is printed on the Capatch and enables the user to read the volume directly against the track of indicator fluid. Units of BCM/inch2 are used in the USA and CC/m2 are used throughout the rest of the world.

 

Since the volume of the indicator fluid is constant inall Capatch strips, the length of the track measures the ink volume of the anilox roll cells.
