There are various aspects that go hand in hand in producing good quality printing on new & used offset printing machines. Ink is just one of these components. While working with offset printing ink, one may encounter a number of problems, such as high dot gain, piling, ghosting, scumming, doubling, slurring, non-gear streaks, and many more. Let’s have a look at some of these issues and their related solutions:

  1. High Dot Gain

This may be caused by two reasons – low viscosity of ink or improper balance of ink & water. In the first case, one may opt for increasing the viscosity, which may render an improved quality. Alternatively, one may also go for a complete change of the ink. In the second case, it is advisable to run minimum water and the minimum ink for attaining the proper density. At times, owing to specific properties of the ink, it may not create a proper balance with water. Hence, one should ensure to take a certificate of analysis from the ink manufacturer and make a note of the values that may suggest its water pickup attributes. Of course, high dot gain may also occur as a result of improper pressure settings, chemistry, or even plates.

  1. Piling

Poor ink and water balance is one of the major reasons behind piling on an offset printing press. To correct this, one may make use of anti piling agents that may be added to the fountain. One may also consider running the water just above the minimum level.  Poor quality of the paper may also cause the occurrence of piling.

  1. Low Ink Mileage

There may be several factors triggering this problem, such as high density of ink, rapid penetration into the paper, and low pigment strength. To avoid this scenario, one should ensure usage of quality ink and paper. Further, one needs to make sure to run only the required density and minimal amount of water.

Of course, there are several other problems that one may face in this aspect.
