Document Summary

The purpose of this test is to determine the length of time needed for ink to dry on different substrates. Properties tested during this test are the ink and how long it takes for the ink to dry. The conditions that these properties are tested are under a pressroom relative humidity and temperature; these should be within the ideal range. This test is important because it shows the amount of time it takes for ink to dry; this will help the press operator or person printing the job. Findings of this test is useful because they allow the producer of the job to consider how long it takes for ink to dry, if this is not taken into consideration, many things can go wrong throughout the process. Paste test specimens in these boxes (include printed strip and set-off strip) This test was conducted under ideal temperature and relative humidity but the results are different between coated and uncoated samples.
