Uses of Ink Rub Testers, Its Applications and It’s Procedures 


Rub testers have a lot of uses and many ways it can be used. This article will focus on its uses of Ink Rub Tester and its application.

Uses of Ink Rub Tester

  • It stimulates an environment to test the rub resistance on printed materials
  • It can also be used to stimulate the actual working environment of the product and helps in the identification of the quality and the method of printing that is needed to be used for printing of labels.
  • It also can be used as a way to analyze the life label by creating an actual environment of application to measure the abrasion resistance of the printed material.

Applications of Ink Testers

Ink testers are not always needed all the time. They are some different scenarios where ink testers are needed. Here are some situations where ink testers can be applied or used.

  • It can also be used to analyze the rub resistance of different materials. It is also used to measure the wearing properties of sample materials that are being considered.
  • It is used to measure the rub resistance that is responsible for the bonding of ink with the printable surface.
  • It is also used to test the abrasion resistance of photosensitive board coating layers.
  •  When trying to analyze the problem of lower printing force, an ink tester can be used to achieve such goals.
  • Ink testers are applied during the printing of labels. It helps to determine the printing method and property of ink to be used for printing labels. It is used to also determine the rub resistance binding of the ink with the printable surface.

Types of Rub Testing Procedures

  • Power

Plugin the power cord to the correct voltage, the display will read a version number such as 1-0. If the machine is plugged in, touching any key will reactivate the display to whatever the previous setting it was before the power went off. If you leave the machine sit idle, after about  60 minutes later, it will automatically turn the display off.

  • Count Button

Each time the COUNT button is pressed the displayed cycle counts will increase by one. When the COUNT button is held down, the counts will increase each ½ second. When the count reaches 10, it will start incrementing by 10’s. When the count reaches 100 it will start incrementing by 100’s.

While the motor is running the COUNT button is deactivated and “count” adjustments cannot be made. The maximum count is 999. Press “Reset” to remove the count number readout. If the motor is running, pressing the reset will also stop the motor and remove the count number to 000. When adjusting the cycle count, the displayed value is the starting point, not the cycle count previously set. If the cycle count is 100 and the motor is started and then stopped at 95, pressing the Count button will set the cycle count to 96.

  • Start & Stop Button

This controls the starting and stopping of the motor. After the count has reached 0’s, the motor will stop and after a short delay, the display will reset back to the number that was displayed at the time of the last start cycle. If the motor is running when the START/STOP button is pressed, the motor will stop. The display is not cleared. Pressing START/STOP will start the motor again and the count will continue from the point at which the motor was stopped.

  • Reset Button

This button will reset the count of the board. When pressed, the display will reset to 0’s. If the motor is running, the motor will shut off. This button may be pressed at any time. When the rub has been completed, examine both the test strips for signs of the transfer. The two pieces should be stapled together and used for visual reference and interpretation. They should be marked plainly with the number of rubs given. Place the test block on its side after using; do not place it on the machine or lay it on the rubber base pad.

  • Wet Rub

Mount the strips in the same manner just like a dry rub, using the two-pound test block. Preset the tester for one rub. Place three to six drops of water on the printed surface so that the test block will cover them. Place the block in position and immediately press the “start” button. After one stroke, examine both surfaces for color transfer. Repeat single strokes until ink failure is noted or the surface of the sample shows fuzz or abrasion.
