Production losses
In the printing industry, regularly testing the volume of your anilox or full coating gravure roll is crucial for preventing production losses. Wear, “doctoring”, improper cleaning can cause incorrect volumes. Don’t assume that your roll has the correct cell volume. Use Capatch to: • Obtain an indication of the volume of your roll • Reduce production stops to five minutes or less • Prevent scrap production • Provide a verification of the volume of a roll after cleaning or maintenance

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

Capatch is an efficient tool that measures the volume of anilox rolls 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.

The Capatch has a tolerance of plus or minus 10 percent. Although it might have a similar tolerance to other measurement instruments such as Wyco, Urmi, Ravol and Volugraph, it is not meant to replace them. These methods take 10 to 15 minutes, or longer, to carry out. The Capatch is an additional tool for use in the printing press and gives a rapid reading but with a slightly larger tolerance. It takes no more than two minutes to apply the Capatch correctly.
