When we started the development and saw the first results we knew that we had a unique product and had to secure it from our competitors." Variable sleeve offset printing is a technology that is said to allow the use of variable print lengths in offset.
According to Drent Goebel, the technology ct combines the advantages of offset with those of flexo and gravure and that VSOP spells the end for traditional size groups.
When changing printing length only two lightweight sleeves need to be changed and length-variable sleeves, which contributed so greatly to the rise of flexo printing, can now be used in offset printing.
VSOP allows the printing length to be steplessly set from 15" - 30" for the 520 and 850 machines, whilst the printing length for the 1120 and 1250 presses varies from 22.5" - 44", which gives the printer a flexible printing press, suitable for a range of jobs.
The company added that the biggest advantage of the VSOP is that the printer can print paper, pressure sensitive stock, all films and foils (even shrink film) and cardboard on the same printing machine.
With the VSOP Drent Goebel believes it has introduced a completely new platform for web offset printing and whilst the offset process is at the heart of the system, other printing technologies can also be incorporated in the same printing unit design, such as flexo and rotogravure.
B A further development of the system is gapless printing, for which the company said the first tests look very promising.
Drent Goebel added that more developments will focus on new sleeve types, new in-line functions, more options for the VSOP and new software features, for example.
In the company's opinion, UV curing has reached the level of performance that is required for the safe production of food packaging but Drent Goebel will also support the use of electron beam curing, or of conventional inks to ensure the flexibility that is requested by the market.
