Another important advantage of the offset process is the scope for adjustment of the ink density used in the printing process. You can adjust the quantity of ink used on the fountain rollers by using the screw keys. The keys reduce/increase the gap between the blade and the fountain rollers thus affecting the amount of ink used in printing. This difference in the ink density leads to differences in intensity of colour. Modern offset printers use an electronic system for screw key control.
The printing equipment used in the offset printing services is simple and uncomplicated. The plates are low on maintenance needs and require very little care. This is what Offset printing Sydney used in making high-quality printing.
Printers make use of toners that are good for a prescribed number of printouts and therefore quality suffers when you go for a bulk printout.
The variations of offset printing

Blanket to blanket uses two blanket cylinders for printing. A sheet of paper is passed between these two cylinders for both side printing. This is a high quality and fast method as both sides of the paper are printed simultaneously.
Variable sized printing uses detachable plates, cassettes or other inserts for single sided and double sided printing.
Keyless offset uses a fresh supply of ink for each round/revolution. Newspaper prints use the keyless offset printing services.
