Factors Influencing the Occurrence of Dot Gain in an Offset Press

Print shops on the lookout of second hand offset printing machines may contact Goodmachine, an eminent dealer of printing equipment.

Dot gain is one of the most common ink related issues that may crop up while working on offset printing machines. During the process of transferring ink from plate to paper via the blanket, the ink, at times, gets squished, resulting in dot gain. There may be several factors that influence the occurrence of dot gain, some of which are enumerated below:

1.      Properties of ink

Of course, the ink itself may be the primary cause behind such instances. The ink viscosity has an important role to play in this scenario. Viscosity basically implies the resistance of ink to flow.  When the viscosity is low, the ink exhibits a tendency to spill beyond the limits of where it was actually intended to be applied.

2.      Temperature of the oscillating rollers 

With the help of an infrared sensor, one may measure the temperature across each side of the oscillating rollers. Experts suggest that the optimum temperature should be 27 degrees Celsius, as this will ensure the least amount of piling. 

3.      Pressure

The amount of pressure applied plays an important role in this aspect, be it from blanket to blanket, plate to blanket, or form roller to plate.

4.      Blankets

Old blankets may trigger the occurrence of dot gain. At times, just using a new blanket does the trick to get rid of the problem.

5.      Machine

If the machine is too worn out, particularly its bearings, gears, and rollers, it may cause dot gains.  Those on the search of a used Adast printing machine or any other branded second hand printing press may get in touch with Goodmachine, one of the most reliable offset machines dealer in the country. All machines sold by them are in great condition and perform as good as new. Here’s An Overview of the Most Popular New & Used Adast Dominant PrintingMachines. 

6.      Ink and water balance  

If the proper ink and water balance window is not being followed, then it may be one of the reasons behind the issue.

Of course, there are several other factors that play a role in this context, such as plate wear, roller settings, paper, and many more.
