Doctor Blade Angle Verifier
A portable tool for measuring the contact angles of used doctor blades. This device takes into account the deflection of the blade for a more precise measurement. In Gravure, the lower the contact angle, the higher the loading pressure that is necessary to wipe clean. In Flexo, it is especially helpful in determining if the chamber or holder is parallel or skewed to the Anilox.
Did you know that many common print problems are attributed to improper contact or running angles of the doctor blades? Over the years, more often than not, we have found that many printing problems are the result of improper contact angles. This is true for both Flexo and Gravure.
It is a must for every printing department and is a great training tool for new press operators. Presses running improper contact angles can waste thousands of dollars press time alone, not to mention; wasted ink and substrate, excessive blade wear, and the potential damage to the rolls. Benchmark your process when things are running well, or if you currently have blade issues use this tool to help solve them.
The new "ARS-INDICATOR" stands for Angle Reflective Scope Indicator. (See figure) This tool allows the press operator to know immediately after pulling a doctor blade what contact angle that blade ran at. While there have been several methods developed to help a press crew set the blade angles on startup, none of these take into account issues such as blade deflection caused by wiping pressure or how parallel a blade is set from one end of the cylinder or roll to the other.
This device will tell you:
- If the blades were set parallel to the roll and everything was lined up properly.
- If you are running in the optimum range for the process.
Includes: microscopic system, custom carrying case (additional cost) reliable LED light source, instructions on how to examine a used blade, and tips on what you should expect to see along with the recommended contact angles for the various processes.
