Leave a comment

The Xerox iGen4 together with the Stora EnsoTM module is an automated solution for the digital production of cardboard packaging. For digital color printing is used Xerox iGen4 machine, UV or aqueous coating with varnish is manufactured by a company EPIC and Die cutting is developed by Stora Enso requirements.

Digital - Xerox Igen4

Digital – Xerox Igen4

The overall system allows clients producing small runs of printed packaging. Since all modules are connected to a single line, we have maximum productivity when making packaging. For example, at the entrance to the system we insert a piece of paper / cardboard, and at the output we have printed and die- cutted packaging sheet, ready for folding and gluing.

Color printing is in charge of the Xerox iGen4 machine with speed of 110 ppm, and it is a unique solution on the market for making printed packaging with format 364×571 mm, and soon is coming format 364×660 mm. The system is completed with an Epic CTi-635 machine for UV or aqueous coating, Stora Enso unit for collecting and transporting sheets and cutter developed by Kama for Stora Enso. The coating is required for many applications in packaging and gives a quick-drying, UV or based on water protection to package from dirt and scratches. Xerox solution Gallop helps protect the environment because it allows printing small runs on demand, reducing the unnecessary cost of materials, and uses cardboards that are recycled and can be recycled again.


Steps in the process prior to printing – Digital printing eliminates steps and processes before printing (making films, lighting plates, assembly, and subsequent corrections). Digital printings is ideal for automating the entire procedure, thereby saving time, energy, manpower and reduce steps in production.

Obsolescence of products – in all industries aim is to reduce waste and scrap. It is completely undesirable to have a lot of ready-made storage containers of ambalage that may never be used.

Statistics show that 40-50% of printed material is thrown away because it will not be used or because the statute of limitations.

Taking care of the environment – almost everywhere is present demand of caring for the environment and the use of recycled materials. The digital process reduces waste, saves material and energy, and therefore contributes to environmental conservation.

Flexibility and speed

Faster process – the traditional printing process for packaging can last for days. With digital, you can have finished packing for a few hours.

The sample for testing – as is the cost to produce a single package the same as for a thousand, digital process is very favorable for the production of samples and test prototype packaging. Thus designers can also check how design influences consumers to choose the right product.

Versions of packages – Digital printing is ideal for packaging that needs to be adapted to the local market, due to a specific geographic area of language, demographics, age group or even completely personalized. In the current economic crisis, all the manufacturers are looking for ways to highlight their brand and reach out to their target clientele.

Marketing objectives

Gallop, Xerox iGen4 automated system for the production of cardboard packaging, is unique on the market. It is the only available system for inline digital manufacturing of paper and cardboard packaging.

Approximately 10% of the production of packaging goes to small print runs. As the largest segment of the packaging industry of graphic production, it represents a huge potential. Gallop technology puts Xerox at the top selection of manufacturers for packaging small runs.

Gallop technology

Xerox iGen4 digital system for color printing. It uses a standard iGen4 system with various modifications in order to improve the printed media for packaging. However, these modifications are not only specific to Gallop system, but can be applied to every iGen4 machine.

Fillers for printing inks

Leave a comment

One of the important components for formulating of inks is fillers or additional pigments. Basically it is important that ink is not too concentrated with pigments because too much pigment will give negative impact on printability of ink.

Market for fillers to grow

Market for fillers to grow

Fillers do not affect the tone of ink, but they have changed rheological properties of printing inks.

Among other things, enhance the colors consistency, so they become more suitable for printing.

Fillers are actually fine-grained white or transparent inorganic powders. As pigments, and they are insoluble in the binder. Fillers added to the binder give transparent dispersion.

Filler task is to replace a certain percentage of expensive pigments and to have positive influence on the properties of printability of inks. In use today there are cheap, mineral fillers, and artificial fillers that are somewhat more expensive.

Artificial fillers are fine-grain white powders, and usually they are received with deposition of hardly soluble salts. These fillers have lower hardness and higher dispersion from natural and so their use is greater.

Because they can change the rheological properties of printing inks, fillers must not chemically react with the binder, or dissolved in it.

Aqueous dispersions of fillers are opaque, and oil filler dispersion was partially transparent.

Fillers can differ in chemical composition and fineness of grind. Central particle size is between 0.01 and 1 micron.

Specific gravity of fillers ranges between 1.5 and 4.5 g/cm3. Depending on the color, fillers must be white or transparent and should not affect the tone of the pigment. Fillers must be resistant to binder in long term strategy, and must not chemically react.

Filler China Klej is widespread in nature aluminum silicate. It is obtained by digging, washing, precipitation, drying and calcination. This filler is white fine-grain powder, with soft structures. It is used for deep and screen printing.

Filler Aluminum hydroxide is one of the most important filler in the industry of graphic colors. It is obtained by deposition of aluminum sulfate. It is characterized with the low specific gravity, high dispersion and is very transparent.

It is resistant to light, alkali and water, but not resistant to high temperatures.

It is used to create multicolored and transparent inks.

The most famous fillers used in the manufacture of printing inks are:

– Barium Sulfate

– Aluminum hydroxide

– Magnesium carbonate

– Calcium Carbonate

– Talk

– clay

– Silica

Drupa 2012 – Innovations and Novelties

Leave a comment

In this article we wanted to evoke the atmosphere and show some of the novelties that were presented by short at Drupa, for all those who have not had a chance to come and a reminder to those who were.




At the Kodak booth an absolute hit was a digital printing machine Kodak NexPress SX 3900. For this, in practice, proven machine, Kodak has introduced a new option – an optional tray that allows printing on substrates up to size 356 x 914 mm (356 x 660 mm in automatic duplex mode), and gold, pearl and neon-pink toner as an option for the fifth printing unit. With the previously launched option for a fifth printing unit such as Clear, Red Fluorescing, Dimensional Clear, Black or Light RGB toners, gold, pearl and neon-pink toner bring an unprecedented range of options that adds to standard CMYK print a new value, thus enabling the expansion of business and increase revenue to the owners of Kodak NexPress digital printing press. These three options will be available on the market early next year.

Furthermore, Kodak introduced the Kodak Flexcel Direct, a machine for direct engraving of flexo printing forms. With laser engraving of elastomer is obtained a printed form with great endurance. The machine is capable of producing sleeves and panels. It is technology that many flexography printers eagerly await.

MGI Digital Graphic Technology

Great interest of visitors to the booth of French company MGI Digital Graphic Technology has caused a new MGI JetVarnish 3D, machine for digital partially coatink with digital inkjet coating technology, which in the latest version, first presented at Drupa, can now be made, and dimensionally, ie partial relief coating at a speed of 3000 sheets per hour for format 52 x 105 cm.

Konica Minolta – KM1

Konica Minolta is at its booth presented a prototype of a new digital ink jet printing machine KM-1 inkjet technology that can print up to B2 format sheets stacked at a speed of 3300 sheets per hour.

Resolution of 1200 x 1200 dpi provides exceptional printing quality. In addition to the proven digital production presses bizhub PRESS Series C 6000/7000 and C8000, Konica Minolta has introduced a new model and prototype bizhub PRESS 1100 C, which will allow printing of high quality prints at a speed of 100 A4 / min, regardless of the grammage of the paper. The launch of this machine on the market is expected over the next year.


Epson Sure press

Epson Sure press

Epson has introduced a new generation of ink jet printing machine for labels from the roll to roll with printing capability of white ink Epson SurePress L-4033AW. This is a digital printing machine for printing labels on all materials commonly used in the production of labels, from paper to foil. With six printing units, CMYK + orange and green, now there is and white ink for printing on transparent and metallic materials. Most manufacturers of labels showed interest in this machine because of the quality of prints and affordable prices.

Techkon this year had a larger booth than usual and a large attendance. Of the many innovations the biggest attention was on new model of spectrophotometer SpectroDens Premium, who was redesigned, with color display and plenty of new features. What is interesting to the younger generation is applications for the iPhone, whit which we can control the registry on the print.


From novelty on boot of British company Morgan, a leader in the manufacture of machinery for processing plants for digital printing, we single out a new range of polyurethane binder (machine PUR adhesive binding): DigiBook 150, 300 and DigiBook 450. By its very reasonable price, along with the proven quality of the Morgan processing plants machines, these machines for PUR binding will certainly find its place in a number of digital printing factories, as well as conventional printers that have a need for quality binding.

Psychophysical color characteristics

Leave a comment

Colorful inks except wavelength are also characterized by three properties:

  1. Tone of ink or tonality of color of inks quality is determined by the wavelength of light rays, which cause the sensation in the eye and color. That is, quality property from which a colorful ink varies from gray. The color of tone indicates type of ink or ink itself.
  2. The degree of saturation or the amount of white is a measure of color saturation or ink purity. The degree of saturation is talking about the absence of white in a colorful ink. A small degree of saturation is said that the color is pale.
  3. The degree of darkness, brightness, or luminance is content of black in a
    colorful ink. In the degree of darkness in which black gives the greatest degree of darkness, means that the tone of ink is equal to zero.

The color that is determined by three characteristics of tone, brightness and saturation can be described in the diagram with 3 color coordinates or in cylindrical coordinate system.

– Saturation is the color distance to the radius vector from the achromatic axis.
As much as the distance from the achromatic color axis is greater, the greater is the saturation of colors.

The color that is determined with these three characteristics of tone, brightness and saturation can be described in a diagram with three color coordinates and the cylindrical coordinate system.

On the psychophysical characteristics of inks are coming adjacent to the physical quantities:

  • Tone of ink represents the dominant wavelength.
  • Saturation is the purity.
  • Brightness is the physical size of illumination.

The tone and saturation together are producers of chromaticity of ink.

Ecological development of ctp plates

CTP plate Agfa Thermo Fuse

Most printing houses is faced with the problem of working with organic chemicals and their disposal. Meeting increasingly stringent standards and the care of the environment is an additional motive for crossing to the no chemical technology. Agfa offers a range of innovative solutions for working with no chemical plates grouped together under the patented name AGFA ThermoFuse.

agfa thermal plates

Agfa plates

By applying this technology with ease of operation, lower costs and reduced environmental impact can be achieved better stability and durability of the entire print production process.

The principle of thermo-technology AGFA Fuse

For standard, chemical CTP systems under the influence of light or temperature-sensitive laser illuminates the surface of the plate. The resulting image is not mechanically resistant and is necessary to develop a chemical process by which the board is prepared for printing. The final result (plate ready for printing) is dependent on a range of analog values such as: the state of chemistry and temperature, rate of passage of the plate through the developer, washing method, grommets and more.

No matter how the elements are controlled and kept within the standard values, final plates are reproducible only within certain tolerances.

AGFA ThermoFuse technology uses the power of lasers to melt extremely small thermoplastic elements that are found in the surface layer of the plate. During illumination thermoplastic particles absorb heat and melt, joined together and formed solid areas which are firmly glued to the aluminum substrate. Dark areas remain in the initial state, and subsequently washed from the plate. With this process in one step we are getting stable and mechanically resistant plates ready for printing. In other words, the plate is fully formed in the process of illumination, and the whole process is 100% binary and dependent only on the laser settings. The only thing left after the illumination is to wash or rinse unexposed particles in areas where there are no pictures.

At the plates: Azura TS rinsing is carried out using water-based solution that includes a means for the grommets, which also serves to protect the plate, while the plates: Amigo TS uses a mild “Clean Out” liquid.

The benefits of technology ThermoFuse

Plates: Azura technology ThermoFuse does not require chemical process, but it is necessary to rinse them after illumination so it is not possible to say that the process is fully processles. Despite this, process brings many advantages over conventional chemical CTP technology and also the processles technology that is applied from other manufacturers:

  • 100% binary process (eliminated the influence of chemical variables in development)
  • Aluminum plate surface is mechanically resistant and suitable for a large number of prints
  • Ease of Use
  • The visible image of the finished plates (measuring wedge plates and checks before placing the printing press)
  • Speed of lighting is almost identical like to the chemical CTP plates
  • A large number of prints (Amigo TS plates without firing can provide up to 200,000 impressions, and with the baking much more)
  • Environmentally friendly technologies
  • Lower cost (less water and energy consumption)
  • Possibility of archival records and reprints (rinsing is carried out with the aid of liquid containing means for grommets)

ThermoFuse technology was developed with the aim of saving and reducing the negative impact on the environment. Aluminum plates use very thin surface layer which is washed in an aqueous solution. Thermoplastic components (latex) are chemically inert. The chemical for rinse the rubber coating is pH neutral (pH value is very similar to the value of tap water) and does not contain alkaline and corrosive agents, and undesirable solvent.

Using ThermoFuse technology significantly reduces water consumption, probably one of the most important and most threatened resources.

Tested and proven technology

Agfa ThermoFuse is a proven technology. Agfa first introduced procesless plates for printing in 2000th: Thermolite, which have been used successfully in more than 100 different models of direct printing machines and excellent are accepted in the market.

Plates: Azura presented at Drupa 2004 are intended for use in standard thermal CtP devices with a laser wavelength of 830 nm.

In the middle of 2010 the new, improved generation of plates are introduced ThermoFuse (Azura TS and: Amigo TS). These plates provide an even greater number of prints, and improved lighting speed.

Existing users of chemical thermal CTP solutions relatively easily and with little investment can go on the boards of technology AGFA ThermoFuse. CTP device is not necessary to change (it is necessary to check the list of supported devices for the desired CTP plate type), or the necessary changes apply only to the process of developing. To work with the plates: Azura TS is necessary to buy a unit for washing while working with the plates: Amigo TS is possible with installation of appropriate brushes to use existing developer for CTP or conventional plates.

Special applications

Great quality print products are getting increasingly popular in the printing industry. A constantly developing requirement for surface finishing techniques has become noticeable over the past few years. You will need an appealing design and top-quality printing and finishing to distinguish yourself out of your competition! Gorgeous print products generate a winning impression, deeply influencing the choices buyers make.

Upgrades in the technological options backed up by presses, including inline surface finishing in a single pass, are also fuelling this development. Advancement has been significantly evident in the section of coatings. There are now a large number of special, user-friendly coatings with new features. They deliver all manner of effects, giving designers ever better liberty of expression.

Cold Foil Finishing

cold foil finishing

cold foil finishing

Cold foil is an magnificent innovative print technology that enables you to apply metallic foil, in-line, at press speed, in an endless spectrum of colors. Cold Foil Finishing can be applied using two conventional offset printing units. The first unit uses its inking unit and also an offset printing plate to apply glue either as a spot application or to the complete sheet.

The second, actual cold foil unit incorporates take-up and take-off units for putting on the foil. Along with the sheet, the foil is fed into the nip between the blanket and the impression cylinders and applied by pressure to the regions of the printing stock covered with glue. Right after the backing is taken away, the metal layer remains on the sheet. The remaining printing units are used to overprint the sheet. CMYK and spot colors can be printed to the sheet and over the foil. The result is a fantastic foil effect.

Drip-off and Hybrid Coatings




Standard inks are used for the process colors. A special-effect print varnish is applied in the final printing unit to the sections that are to have a matt appearance. Then, the coating unit is used to apply a conventional full-area high-gloss coating that drips off the spots previously given a matt coating. This maintains the matt effect of these parts and offers the remaining spots a gloss surface.


Hybrid or UV inks are utilized for the process colors. A further printing unit is used to utilize a UV special-effect print varnish to the areas of the picture that will have to have a matt visual appeal. Next, the coating unit is used to implement a full-area UV high-gloss coating. Because a UV high-gloss coating is used for hybrid applications, a greater gloss intensity may be achieved compared to a drip-off application produced by using a conventional, water-based high-gloss coating. With hybrid applications, however, the structure of the matt effect is much stronger than with drip-off applications.

Hybrid and UV Spot Coatings




UV inks are being used for the process colors. An extra printing unit applies a hybrid special-effect print varnish to the regions of the picture that will have to have a matt appearance. After that, the coating unit is used to apply a full-area UV high-gloss coating. The matt effect is produced exactly where the gloss coating \”sinks\” into the special-effect print varnish.


UV inks spot-coated with a UV matt varnish in a additional printing unit are used for the process colors. Next, the coating unit is used to put a UV high-gloss coating as a second spot coating. This evidently separates the matt and gloss sections. As a UV high-gloss coating is utilized for the hybrid application, the gloss level is comparable to that accomplished with the UV application. The matt effect in the hybrid application, nonetheless, has a surface which is less smooth compared to the UV application, recognized as a hybrid effect.
