Karat Digital Offset Press

The 74 Karat is an offset press optimized for short to medium runs of four-colour print jobs. Engineered specifically to meet the changing needs of the printing industry, the 74 Karat:

 
  • Enhances Productivity by dramatically reducing makeready, paper waste and consumables consumption throughout the printing process, so more jobs can be printed per shift at a lower cost per job;
  • Delivers consistent and predictable colour with minimal operator intervention by incorporating proven colour management principles and press controls to eliminate colour fluctuation and registration problems on press;
  • Prints to rigorous commercial offset standards, e.g. by eliminating more and using Turbo Screening to support maximum screen rulings and smooth vignettes

These properties are supported by the following features:
 
  • A compact design with a common impression cylinder;
  • A Gravuflow keyless inking system that delivers saleable colour in just ten sheets;
  • Commercially proven waterless inks;
  • PEARLdry waterless aluminium plates with automatic loading, unloading and on-press thermal imaging;
  • Extensive automation of major press functions, with control via a user interface.
The print quality delivered by the 74 Karat can stand comparison with any high-class, four-colour offset press. This includes its ability to lay down high density, smooth solids and a crisp, uniform dot structure across the entire sheet. The 40-diode thermal imaging system can produce screen rulings of 80l/cm (200lpi) or more.

The 74 Karat is a B2 press with a maximum rated output of 10,000 sheets per hour on a wide range of paper types and weights. Designed for one-man operation, the press has a cycle time (i.e. from the last good sheet of one run to the first good sheet of the next) of just 17 minutes.

The 74 Karat is designed to combine the proven qualities of offset with the convenience of electronic imaging and an automated workflow, eliminating the need for intensive manual intervention. The result is a neat, accessible and highly automated machine that is big on performance but small on manning.

 
 
46 Karat – the little sister

Is a product of a strategic alliance with Presstek Inc., USA. Engineered like the 74 Karat, for quick fire short run colour, and featuring the same compact design and cylinder arrangement, the 46 Karat differs on three accounts:

 
  • It has conventional roller-type inking units with ink keys and four forme rollers;
  • It incorporates Presstek’s ProFire imaging technology;
  • It uses Preestek’s PEARLdry Plus waterless plates.
  • The ProFire system features multi-beam lasers that form screen dots direct on the mounted plate. It supports an image resolution of 1270 or 2540dpi, an 80l/cm screen and can image four colours in 4-5 minutes at 2540dpi or 2-3 minutes at 1270dpi.
  • On the 46 Karat the entire printing sequence – from plate advancing and imaging to printing and blanket cleaning – is automatic.
