Rotatek Universal Offset:

Note: Rotatek will introduce an 850 model at Drupa. Contact us for information.

Introduction:

The Universal is a variable repeat offset sleeve press where each printing unit is equipped with interchangeable lightweight sleeves. The variable repeat is obtained by changing only the plate and blanket sleeve, so the web is not broken and is an extremely easy and quick system.

The sleeves are patented by Rotatek's unique design of creating ring bearers to support high printing pressure that cannot be replicated by any other manufacturer. A simpler mechanical locking design also allows for quicker change over without the need of air positioning.

The universal is a fully automatic inking, register and tension control system. Full servo motors allow individual control of the units to obtain perfect register and size even with the most difficult substrates for offset quality.


Rotatek has been answering the market challenges with strategic innovation from more than 35 years of experience manufacture high performance presses for the label and flexible packaging market.

Our latest innovations are focused on combining offset with different technologies for printing on a wide range of substrates. The revolutionary Universal machine has been designed to satisfy the most demanding requirements of our customers.

  • Outstanding Offset Quality:
    Recognized worldwide as the highest quality printing process.
  • Redefining Flexiblity: Changing repeat using our unique, patented ring bearing offset sleeves for unmatched durability.
  • Costs: Offset Plates are much cheaper than Flexo (Plates) and Gravure (cylinder).
  • Environmentally friendly: Due to the use of curable UV or EB inks.




Variable Repeat:

The printing units are equipped with interchangeable lightweight sleeves. The variable repeat is obtained by changing only the plate and blanket sleeve, so the web is not broken and it is an extremely easy and quick system to use.

The sleeves are genuine offset with ring bearers to support high printing pressure and they are designed to work without any need of air for positioning. The simple mechanical locking device allows a very quick sleeve change.


Combination Press:

With the latest servo motor technology, the totally modular concept of the UNIVERSAL machine allows for multiple configurations and combination of different printing technologies (offset, flexo for varnishes and spot colors, screen for Braille applications or rotogravure for applications such as gold or silver inks), processing and finishing (cold seals laminations, cold stamping, die cutting, sheeter. etc ..) to obtain a top quality finished product in a single pass.



Fully Automatic:

The UNIVERSAL machine is fully automatic regarding the inking system, register, and tension control.


From the PDF of pre-press to the central computer, the machine automatically sets the color curves into the automated ink fountains of the different printing units. The marks controlled by the automatic register link into the servomotors of the machine, which gives a fully automatic set up in a very few minutes, giving an astonishing result in the minimum waste of printed material.

All modules of the machine are servo-driven. This technology allows individual control of the units to obtain perfect register and size even with the most difficult substrates, giving offset printing quality which is totally constant from the first to the last meter.


Curable Inks:

Due to the amazing advances made in the technology of 100% solid inks during the last 15 years, these are now capable of being transferred onto non-absorbent substrates such as films, foils, aluminum and polyolefin which has opened a tremendous range of opportunities for Offset Technology in the world of labels and the flexible packaging.

The main advantage is the total absence of solvents in the curable inks therefore not producing VOC's (Volatile Organic Components) and the saving of solvent recovery or incinerators costs combined with the lack of production of CO2.

The 100% solid UV and EB inks are ideal for transfer in offset printing.
