Offset sheet printing technology is the transfer of printing ink first from the printing plate to the offset rubber cloth (ORTP), which is fixed to the offset cylinder, then from the ORTP under pressure to the printed material.

As print white space and printed elements are in the same plane, they have different chemical nature and properties: elements designed for printing ink wetted with paint and repel water, and spacing elements can perceive and the water and paint, so the first printing form passes through the wetted humidifying and moisturizing solution of whitespace elements, and then the remaining uncoated printing form elements take the ink; this forms the printed image.

Transfer of printing ink from ORTP is carried out sequentially from all sections of the printing machine to the printed material, which then passes through the coating module, where water-dispersion or UV-varnish is transferred to the impression using an anilox shaft with a fixed cell volume and a coating cloth.

We have gained a lot of experience in the technology of offset sheet printing and varnishing, we are constantly improving and do not forget to adopt the latest techniques and foreign competencies. Briefly about our directions in offset sheet printing:

• When using offset printing technology with oil paints, the impression is fixed on the surface as a result of an oxidative polymerization reaction and partial absorption into the printed material. The prints have good color and tone transfer indicators, allow for post-printing finishing, but the technological process takes more time for interoperative drying before further processing, which affects the efficiency of production.
• When using offset printing technology with UV inks, the impression is fixed on the surface instantly as a result of the photopolymerization reaction. Prints have a high color saturation and gloss, have high mechanical resistance, resistance to high temperatures and chemicals. The cost of materials for UV printing is more expensive, and the technology itself is more energy-intensive and expensive.
• When using technology of varnishing with water-dispersion and UV lacquers , the application takes place in a special lacquer section on the principle of high (flexographic) printing, which allows you to apply a large amount of varnish to the impression and ensure the protection of paints from abrasion or the necessary visual effect.
  The lacquer section of the chamber-squeegee type, with additional adjustments to the pressure and temperature of the varnish, allows you to apply the varnish with a guaranteed even and uniform layer and ensure stable quality of varnishing. The amount of varnish applied is regulated only by the type and volume of cells of anilox shafts, which are enough in the assortment. Affectionate forms are made on specialized equipment – cutting plotter. The plotter cuts the top layer of the canvas, and whitespace elements are removed before printing the print run. This method allows you to work with simple configurations. When using complex, non-linear or thin patterns, flexo-polymer lacquer forms are used for selective varnishing.
  In contrast to water-dispersive lacquers, prints with UV varnish have a high gloss, UV varnishing is combined with other types of varnishing to obtain interesting and stylish surface effects of products.
• When using the technology of oil varnishing, the varnish is applied from the printing section in line with the print, using a regular printing plate. This method allows you to create a paint area configuration of any complexity. As a result, the prints also have glossy, matte surfaces, but the drying of oil varnish is much slower than water-dispersion lacquers and the abrasion resistance is significantly lower. Special siliconized offset lacquers are widely used in combination with UV lacquers to achieve the effect Drip-off.
• The Drip-off (or Twin-varnishing) technology allows you to get a structural-glossy or Matt-glossy effect in one run. In the printing section, a special primer is applied from a regular printing plate – in fact, it is an offset varnish (Matt or glossy, oil or UV), which has a given (low) surface tension after application. In the next varnish section, a special glossy top coat is applied (it can be water-dispersion or UV varnish) – and its special properties are due to the low wettability of the surface. For a pair of oil and offset lacquers, varnishes that create a matte-glossy contrast and do not form a structure (grain) are more often used. A pair of UV lacquers, on the contrary, is very difficult to achieve a matte surface, but the structural effects are very pronounced and diverse. It should be borne in mind that the glossy UV varnish in a pair of Drip-Off has a low slip compared to standard UV varnish, so when planning a package with a Drip-Off effect for filling on automatic lines, preliminary tests should be carried out.
• The technology of varnishing Soft-touch and Sand-Touch consists in applying specialized lacquers to prints, which give the surface in the first case (Soft-touch) - a pronounced matte finish with a velvety effect, in the second (Sand-Touch) - the effect of sand.

We print and varnish on modern equipment:

• HEIDELBERG SpeedMaster XL106-7+L – this is a hybrid sheet offset printing machine with extended drying, with a chamber-squeegee coating system, which has 2 independent wash contours, 2 varnish contours and 2 varnish stations for fast switching from one printing mode to another and ensuring stable print quality in each of the modes.
• HEIDELBERG SpeedMaster XL105-6+L– this is a sheet offset printing machine with extended drying, with a chamber-squeegee coating system.
• We control the quality of prints using the latest automated spectrophotometric system for quality control of color and printing process Heidelberg Image Control. This system allows you to comprehensively evaluate the impression by measuring the indicators of the operational control scales, perform a check on local key areas of the image, and make immediate adjustments to the printing process control system. The key advantage of the system is the standardization of work and ensuring stable repeatability of color indicators of prints. The system also allows you to inspect the printed impression for errors in the printing process or the manufacturing process of printed forms.

Our equipment allows us to work with films of different types BOPP, OPP and PET with a thickness of 8 to 40 microns, reproduce 3 film pressing technologies:

• Pre-pressing occurs when a hot-melt film is fed from a roll (BOPP film with a pre-applied layer of glue) and passes between two shafts (one of which is heated) under pressure.
• Pressing occurs when the film is fed from a roll (BOPP or PET film without glue), the glue is applied to the film with intermediate drying and passing between two shafts (one of which is heated) under pressure.
• Pripressovka occurs when feeding the film from the roll (PET with chemical. the processing of film without glue), applying glue to the cardboard with dryer and a passage between two shafts (one of which is heated) under pressure.

We produce the hot stamping process on modern and high-performance presses from the company BOBST with the maximum size of the printed material 1040 x 740 mm.

In the technology of hot stamping foil the color metallized film is transferred from the intermediate base (foil) to the material to be sealed when the cliche stamp is exposed to temperature and pressure. When there is a foil between the stamp and the printed material, the cliches heat up and melt the foil separation layer in the area of the printed elements, the pressure allows these printed elements to be fixed in the desired area of the impression.

We carry out hot foil stamping – from flat to Congreve: relief, two-level embossing, multilevel embossing and 3D convex, and also microembossing, which, in addition to the decorative function, has a protective function (protection against counterfeit) and debossing – reverse Congreve, where the image level is lower than the material level.

In compression technology holographic foil it has its own specifics. The structure of a holographic foil is similar to that of a conventional foil, but there is a strict requirement for the accuracy of the impression drive relative to the printed image. for this purpose, special optical labels are used during printing and press drive control systems.

Cutting technology it is a "cutting out" of the package scan with the application of the required structural elements (creasing, rolling, perforation) over the entire area of the scan. Cutting occurs at the moment when the sheet falls between stantz-form and its response part. Counts form is a plywood base on which is fixed a sharp curved blades of steel.

Congreve embossing technology it is a way to get a relief image in various places of the package. This image is obtained as a result of passing a sheet between two parts of Congreve cliches that fit together like puzzle elements. Cutting is carried out either in one run with Congreve stamping, using a single rod-form, or the processes take place separately from each other! Congreve embossing can also be combined with other types of post-printing processes, such as varnishing, foil stamping, and lamination.

We work with a fleet of equipment that includes automatic cutting presses of the company BOBST. The equipment is equipped with various optical, mechanized quality control systems that are high-performance and allow you to ensure the operation of the equipment non-stop. Our equipment allows you to use jobsavers in the equipment – metal response plates with saved work on installing and positioning cliches. This allows for fast readjustment, high alignment accuracy, and repeatability within a print run, from print run to print run.

Technology for pasting Windows in the traditional way it is a local gluing of a rectangular polymer window on a cardboard blank with a carved window. The glue is applied selectively from the letterpress form, and the glue layer is thick enough. In this technology we are working on the equipment KOHMANN F 1050/2 manufacturer's ESATEC. This technology is relevant to the customer who needs a thick, durable film that does not sell and break, and/or if the customer is strictly tied to this technology.

This technology allows you to use a wide range of films used, with a thickness of 20 to 300 microns and the following range: PET, PS, PP, BOPP, color and transparency don't matter.
