COMEXI GROUP, ALWAYS AT YOUR SIDE SINCE 1954

Offset printing is dominating the printing market nowadays with more than 56% printed in such technology. When it comes

to flexible packaging the scenario is completely different with negligible impact.

THE COMEXI OFFSET SOLUTION

Comexi and its holding company COMEXI GROUP were set up as a business venture guided by a spirit of excellence.

Our nature as a family business moulds our values and marks the Group with the legacy of its founder to pursue long term sustainable activities. Our strategy is to become a leading global supplier of machinery and services for the flexible packaging industry by offering highly specialized services in each product line (printing, laminating,

slitting, rewinding and logistical and environmental solutions) that complement each other and thus give our customers end-to-end solutions with maximum synergies.

Our philosophy is aimed at constantly adapting to the demands of the market and continuously striving for excellence in order to fulfill our customers’ needs.

You can benefit from our product portfolio to adapt your business to the ever changing flexible packaging market scenario.

Gravure (COMEXI ACOM) and offset (COMEXI OFFSET) printing are also part of our printing solutions. Gravure printing is leading the Asian and Indian market and for that reason we offer high quality and efficient solutions from the technology of CCS (Comexi Converting Solutions).

The COMEXI OFFSET press is a new product line based on a central impression drum (CI) and focused on the flexible packaging market on films which embodies the essence of Comexi Group’s strategic principles: innovation with a global impact and the ability to provide the industry with global solutions. The offset printing will be offered to Comexi Group’s customers, giving them the following benefits: lower costs per square meter, high quality (fading screens/fine screens/micro text) added productivity decreased, ecological impact thanks to the solvent free EB offset inks, and higher energy efficiency.

When it comes to converting, lamination and slitting are also the partners for you. COMEXI NEXUS, for laminating, and COMEXI PROSLIT, for slitting and rewinding, are then the right partners if you are looking for the most innovative and efficient solutions.

When logistics and environment matter, COMEXI ENVIROXI is able to offer solutions to automate your factory and the converting processes involved in. Additionally, the market faces many new requirements to reduce green house gases (GHG’s), and to monitor and report industrial carbon footprints, so then COMEXI ENVIROXI can help you to reduce your impact on the environment and your processing cost.

On top of that, our customers are well-supported through our extensive sales network, that includes branch offices in five countries, a manufacturing facility in Brazil and sales representatives in more than 65 countries.

For more than 50 years we have been at your side helping your business grow thanks to your commitment to innovation.

As experts in the flexible packaging market we know the difficulties our customers are facing on a daily basis, but according to different sources the flexible packaging market will be leading the market growth in the years to come. Basically thanks to the population growth and the changes of the standard of living in the emerging countries as India and China. It is commonly accepted that CI flexo technology is the technology better adapted to short runs and light gauge material, which seems to be a clear trend. However offset and gravure will also play an important role. Offset technology is based on paste inks basically focused on folding carton, paper

packaging and certain niches of labels. It is considered the best printing technology in term of quality printing and cost of the plates. The big debate has been its printability potential regarding flexible packaging on non absorbent and stretchable materials.

But Comexi did it! Based on our expertise on flexible packaging and central impression technology COMEXI OFFSET brand offers to our customers cutting-edge technology for printing flexible packaging substrates on a central impression (CI) offset press , and making use of EB inks.

MARKET DRIVERS FOR THE PRINTING TECHNOLOGIES

COMEXI OFFSET considers the following four market drivers to be the most relevant for the converting process:

- There is a clear trend for shorter print runs due to the demand for private labels, the need for product differentiation and the growing demand for specific marketing actions.

- A printing tool and process to guarantee the highest quality levels required in today’s packaging markets.

QUALITY TIME TO MARKET ENVIRONMENT COST

- Increase printing efficiency by reducing press down-time due to fast pre-press, job set-up and reduction of the printed stock.

- A more sustainable converting process due to elimination of solvents and reduction of energy consumption, both leading to a reduction of the carbon footprint.

COMEXI OFFSET is the best suited solution to cover all the previously mentioned demands of the packaging market:

OUR COMMITMENTS- COMEXI OFFSET printing offers the best quality level without

the past serious concerns about the feasibility of offset printing on non-absorbent and stretchable materials.

- COMEXI OFFSET out performs gravure and flexo by far in terms of time to market and production flexibility thanks to its capacity of producing new offset plates in-house within minutes.

- Offset plates in general are up to 20 times cheaper compared to photopolymer plates or gravure cylinders imaging. This enables the printer to achieve the best competitive price for short and medium run jobs. Allowing to improve margins and increase volumes in relation to the competition using traditional processes

- Environmental aspects are going to be major drivers in the years to come. In some part of the industry they are already considered as a key factor. Therefore, from a sustainability point of view, COMEXI OFFSET presses make use of EB inks in conjunction with our commitment to ecological aspects. EB technology will pave the way to a more sustainable printing industry.

- Our EB Flexo coating solutions for white inks, lacquers and varnishes, will be part of the system.

Flexible packaging with increasing product fragmentation which lead to short and medium runs. Looking for a high quality, cost effective solutions with a low impact on the environment.

Sleeve and servo technology

Light weight sleeves made of aluminum or PU-composite (available from various manufacturers) allow a repeat range in infinite steps and fast job change.

When the current print job on the press is finished, the sleeves for the next job are standing ready, with plates and blankets mounted, to be loaded in the machine and to get the new job going within minutes.

Servo drive technology, on the individual printing cylinders, combined with the CI (Central Impression) design, guarantees fast color-to-color register set-up, and high register accuracy during the whole print run.

Faster pre-press

Litho offset plates can be imaged and processed in minutes and are ready for immediate use on the press. This reduces press down time and guarantees that the next job is ready and prepared before the current job is finished. Offset pre-press also allows more flexibility in production planning and thus a great benefit for the brand owner.

Automated Job set-up

Due to the high level of automation of press functions all parameters can be stored and recalled for identical or similar print jobs. Ink fountain profiles can be easily preset with the ink coverage data from pre-press (CIP4). Ink/water curves can be freely selected from programmed curves to individual modified curves.

Job data storage recall

Recall all data from a previous identical or similar job and get the press ready to run within minutes.

EB curing

Electron Beam curing is a process where the ink basically is a fluid mixture of monomers and oligomers, completed with pigments and other additives.

Passing the EB unit, the fluid ink is penetrated by electrons at a high speed. The energy, released when the electrons hit and penetrate the fluid layer, starts the polymerization process of the inks, leaving a complete solid ink layer on the printed substrate.

No Photo Initiators

Unlike UV curable inks, EB curable inks do not contain any photo initiators. Typically photo initiators are the components in an UV ink that tend to migrate The absence of photo initiators in EB inks reduces strongly the risk of migration issues and makes this process perfectly suitable for the printing of food packaging applications.

Reduced heat impact

EB curing systems produce less heat than UV curing systems due to its lack of IR radiation. The heat impact of UV systems affects the substrate and all the press components in nearby areas in a negative way, creating deformation and tolerance issues. UV systems require additional cooling on the press increasing costs for operation.

No solvents

Litho EB inks do not contain any solvents. When passing the offset roller train the thixotropic character of the ink reduces the viscosity drop. This behavior in combination with the dampening water and the correct temperature of the roller train will lower the viscosity sufficiently to achieve the required properties for optimal ink transfer.

Low energy consumption

Comexi Offset CI8’s inks do not need to vaporize its solvents by means of hot air and therefore there are no solvents to recover.

The total energy consumption of an EB litho web press is much lower in comparison to other FP printing processes, since it does not require either hot air or an incinerator for the drying process.

CI design

The CI (Central Impression) design is superior over in-line design litho web presses due to the superb position stability of the web on the surface of the CI.

Offset process standards

The offset printing industry is characterized by its high and international standards laid down in the various ISO standards, but also in the process standards of many leading institutes like FOGRA, GATF, ICC and others.

Multiple Screening technologies

Apart from reproduction from 2% until 98% and until 160 l/cm (400dpi), offset technology is perfectly capable of working with most modern digital screening methods.

Secure brand technologies

Offset’s accurate process repeatability combined with the right set of standard procedures secure stable and predictable color reproduction, independent from geographical location or time of the year.

Thinner substrates and waste reduction

The CI (Central Impression) allows running thinner and more elastic substrates in comparison to in-line press designs. Its high level of automation significantly reduces the material waste.

Low cost litho plates

The price of the plates impacts directly on the production costs and it increases exponentially as the print run is reduced. However, the low cost litho plates used on offset printing allow a competitive price even for short and medium runs.

Litho plates & pre-press

Pre-press for offset plate making is typically done in-house close to the press, which makes it the fastest of the conventional printing technologies. The imaging of the plates is very fast and at low costs compared to the conventional flexo plate making or gravure cylinder processing. Cost of the offset plates is low and plate imaging and processing is done in few minutes. Offset allows you to choose from the widest range of screening technologies, to have the perfect match to your product.

Non printed stock

The fast pre-press and low prepress costs in combination with exact job repeatability allow individual short runs at a competitive price level. No need for gathering multiple short run jobs over a period of time, including storage of the bulk of the printed stock, to cover future deliveries.

Production planning

The short pre-press times and fast press make-ready in offset allow more flexibility when it comes to produce late orders just-in-time without jeopardizing the actual planning.

(With the speed of offset pre-press and press make-ready you can deliver before your competition has even started!)

Daily cleaning maintenance

Using EB inks, cleaning of the print units is not required on a daily basis. The EB inks can stay overnight in the roller train without the risk of drying or skin forming.
