The Comexi Group, a leading company specialist in machinery solutions for the flexible packaging conversion industry, has recently reached an agreement to install the Comexi OFFSET CI8 in the Korean-based Daesung Packing company. Mainly focused in gravure printing for food packaging, Daesung Packing has trusted this outstanding technology to boost its sales in the Korean market, attracting new customers who seek high quality in short runs. In other words, to respond to stringent customers demands by providing innovative packaging in a very short delivery time while respecting environment. Additionally, as the Comexi OFFSET CI8 will  be  installed  in  a  new  factory,  Daesung  Packing  no  longer  needs  to  invest  in  peripheral equipment such as incinerator, distillatory or anilox cleaning system.

The new plant is completed with other Comexi solutions. Besides the Comexi OFFSET CI8 has acquired a Comexi NEXUS SL2 solventless laminator and a Comexi PROSLIT S2 DT double turret rewinder slitter, which allows Daesung Packing to run a solvent-free factory. In this sense, the electricity will be produced by solar and heat-recycling device, meanwhile geothermal energy will be used for heating system, enabling Daesung Packing to operate its factory with only half energy  consumption  in  comparison  with  other  converters.  This  sustainable  commitment  is certificated   with   ISO   14000   (environmental   manangement),   ISO   22000   (food   safety management) and G7 (color management).

The  Comexi  OFFSET  CI8  becomes  the  suitable  solution  to  strengthen  Daesung  Packing positioning as environmentally responsible printer while maintaining high standards of quality, through a simple process very close to digital technology but with a greater production capacity. This  is  enabled  by  joining  the  advantages  of  both  offset  variable  lengths  and  flexo  central impression drum printing in one single press for flexible packaging and labels.

Market demands as opportunity for market leaders  
It  is  not  new  that  flexible  packaging  has  been  facing  the  rising  costs  of  materials  and  price pressures  while  run  lengths  have  been  decreasing.  Within  this  scenario,  operating  costs  and specifically changeover times and waste are key factors to take into account when deciding the best printing solution.

Brand  owners  are  increasingly  demanding  to  add  value  to  their  packs;  highest  quality,  fast delivery  and  competitive  prices  are  perhaps  never  ending  requests.  Those  demands  are challenging the capabilities of the converters with traditional technologies. It is an opportunity for those converters to introduce an innovative technology that easily solves those requirements and simplifies operational processes.

For the current flexible package printer excitement, Comexi Group is promoting to the market a central  impression  offset  variable  repeat  printing  technology,  which  looks  set  to  transform Comexi Group Industries, S.A.U. flexible  package  printing  into  a  more  sustainable  future.  Worldwide  announced  by  Comexi Group  in  2012,  the  Comexi  OFFSET  CI8  press  is  the  market  leader  for  sustainable  short  and medium runs.

The  benefits of  combining  fast  job  changeover with EB  curing  technology  Comexi  Group  has developed a press that replaces solvent inks by using EB curing technology, which allows the use of solventless and instantaneous cured inks without photoinitiators, fully compatible for its use in  food  packaging.  Its  fast  job  changeover,  high  printing  quality  and  pre-press  low  cost  also characterize  the  Comexi  OFFSET  CI8.  All  these  benefits  are  combined  with  a  much  cleaner printing process in comparison with flexo or rotogravure technologies.

The  offset  technology  provides  maximum  flexibility  in  the  production  process,  allowing  very short time-to-market, due to the fast in-house pre-press that allows preparing a new job while the press is still carrying out a previous one. The printing cylinders are easy to exchange manually (automatic cylinder exchange is available as an optional) and all job parameters can be digitally stored and recalled. The pre-setting of mechanical adjustments like ink keys, form-rollers and printing cylinders are automatic.

Another point to be highlighted is the considerable savings for the companies due to the fast and keen in-house plate making. Offset technology is characterized by the use of lithographic plates,  with  much  less  costs  compared  with  photopolymers  or  engraved  cylinders  used  in traditional flexo and rotogravure technologies. The cost reduction at this part of the process allows changing the design and language, adding new logos or making promotional campaigns without additional printing costs. It also allows reducing minimum print runs and printing film in stock.

The  Comexi  OFFSET  CI8  press  use  servo  drive  technology,  allowing  fast  production,  reduced press downtime and start-up waste. The machine prints in up to 7-colors, plus white or lacquer, with a web width of 900 mm or 1100 mm, at a maximum speed of 300m/min.
