While carrying out tasks on an offset printing unit, one needs to check a variety of things, starting from the condition of the machine, to the quality of raw materials, and much more.  Here are just some of the pointers that will ensure that one achieves the best results:

  1. Check roller settings

To start with, one needs to check the roller settings and ensure that they have been set as per the specifications listed out in the manual of the offset printing machines.

  1. Proper ink and water balance

There are so many problems that may occur due to an improper ink and water balance. One needs to remember that increased water always triggers piling. Again, low water may also enhance piling, simply because it would encourage deposit of ink particles on the blanket.  Hence, an optimum balance needs to be attained between the two factors. If one can carry this out successfully, one can surely avoid problems such as scumming, piling, and several others.

  1. Gumming of plates

At times, the plates are extremely sensitive; hence, it is important to make sure that they are being gummed properly.  It is a good idea to gum the plates, whenever the press is not being used for a considerable period of time.

  1. Paper quality

Printing is carried out on all varieties of paper depending upon the requirements of the customer. However, there are some papers that are uncoated, which makes the press easily deliver up to a lakh of copies without causing the blanket to undergo piling. On the other hand, coated papers can produce build up on the blanket merely after the press has delivered 30,000 copies. This is primarily because coated paper cannot absorb water and ink, thus leaving them to pile up on the blanket. Further, use of abrasive paper may damage the plates.

  1. Quality of Ink 

Though ink is accountable for only 3% of the cost, but it contributes to almost 97% of the quality.  It is for this reason that one should always make use of good offset printing ink. One needs to speak to the ink manufacturer to ascertain the water pickup value of the ink.
