The volume of the anilox roller depends on the type of finish to be achieved.
Extremely High builds, such as braille print, require a large anilox volume (70 BCM) to accomplish a successful outcome (see braille image & 3D image above)
High builds to obtain an impressive eye-catching product (see hexagonal pattern image above), calls for engraving volumes of 40 to 50 BCM
Builds for matte finishes often use volumes in the 30-35 range (see folder image above)
The characteristics of tactile varnish demand an engraving capable of picking up and transferring solution to the substrate. This is achieved with a Tri-Helical pattern engraving. The angled rows of lines work as a paddle wheel to pick up enough tactile varnish from its reservoir, and transfer to the screen.
The most common Tri Helical engraving LPI run between 70 and 120 lines, depending on the depth.
Will I go through a lot of doctor blades?
Considering the source, it is extremely likely you could use more than a normal printing process. Contact your doctor blade supplier to find out the best solution for your application.
How do I clean a tactile varnish anilox roller?
After use, utilize the recommended cleaning agent by the varnish supplier before storing away. Do not allow varnish to dry on anilox!
How long does it take to make an anilox roller for tactile varnish?
Although the anilox roller base is standard, the amount of ceramic coating needed to build the deep engraving can be as much as five times that of a conventionally engraved anilox roller. Once the ceramic coating depth is achieved, the anilox roller will move to the engraving department, where the Tri-Helical pattern is created. This generally takes about five to ten times longer than a typical engraving. Lead times for Tri-Helical engravings from CTS Industries runs 2-4 weeks.
