LithoTack II tackmeter

The new LithoTack II is two laboratory instruments in one. It can be used for precision tack measurements as well as to determine water balance behavior of thin ink film under print relevant conditions.

​Most importantly, the LithoTack operating conditions such as speed, film thickness and temperature are similar to those found on a printing press. A test takes a few minutes – so you can characterize and optimize your products quickly, ideally for R&D and QC.

Important questions

• Is there a good interaction between fount and ink?
• How large is the water tolerance range for good print result?
• Will the change to ink B instead ink A or the change to fount Y instead fount X have an essential effect to the print quality?
• Is a bad cleaning up of the plate more caused by the fount or more caused by the ink or more caused by the plate?
• What would be the better ink or the better fount for printing with less water?
• Can I print with less alcohol?
• Is there a higher tendency for free surface water?
• Is there a higher risk for scumming?

These and more can be answered with the LithoTack II  at an early laboratory scale. Modern sensors for micro wave water content sensor and high speed tack are used to scan the emulsion properties in roller nip – the exact position where an emulsion is created.

These and more water balance parameters can be measured quickly and accurately under press conform conditions

• minimum water content required for plate cleaning and maximum water content for correct tack (water tolerance range)
• Interaction with hydrophobic and hydrophilic surfaces (for example, plate clean up)
• Dynamics of water pickup and water release
• Linetack as function of water content (includes a tack measurement of a dry ink)
• Amount of free surface water
• and more
