Drying Time Tester

 Article number: 533.000.000

The Drying Time Tester is designed to determine the absorption behaviour and drying time of inks printed on paper, carton, plastic or metal foils.
Set-off characteristics of otherwise coated or laminated materials can also be tested.

The Drying Time Tester is equipped with 8 test stations, arranged at equal distances from each other. Each station consists of one 25mm wide pressure application roller and a corresponding counter roller.

Printed or laminated samples are placed with the printed side upwards, facing a reference set-off paper, or the back, or the front of a same paper, and run through the test station at a fixed speed.
The wet ink film produces a 25mm-wide set-off trace on the counter paper until the ink film is completely dry. The duration of the drying respectively the drying time can be determined by measuring the length and density of the set-off trace on the counter paper in relation to the selected speed of movement. The speed can be set between 10 and 200 mm/h.

If it is required to test the absorption behaviour by set-off more critically, excluding the influence of the counter paper, it is also possible to set-off print samples against non-absorbing counter samples, such as PVC, cellophane or metal laminated paper.
Other tests include the use of printed sample as well as counter samples made of non-absorbing materials.
It is also possible to mount press samples, full length, cut to 40 mm width, length e.g. 500, 700 or 1000 mm.

Evaluation of test results
Drying time is determined by measuring the length of the counter print image. Measured is the length of the print image to the point where there is no transfer to the counter sheet anymore. The length of the counter-print divided by the set speed gives the drying time.
A drying time curve can be determined by measuring the density of the print or counter print every 10 mm of the print.
