Solutions for Security Holograms Production
Recombining is the process also known as step and repeat, multiply the single image from Master hologram. The result is big size holographic plastic plate -in narrow web embossing usually up to 12″x12″
Electroforming and recombining complete prepress process for mass production of holograms. Work shims are used as instruments for hologram embossing.
The first step in mass hologram production is to create printing plates called Holographic shims.
Printing process in Holography, called Hologram embossing, transfers the microscopic surface relief created during the Mater origination onto special embossing base materials.
The process of preparing tools for mass hologram production pass through the following steps:
Electroforming is the process of copying holographic images. Depend of task it maybe converting image from photo-resist or plastic to metal (nickel), or just metal-metal copying.

For long years we offer laser hologram demetalization. Year after year, demand for this product increases and we came to the consistent decision. The equipment we have designed has no analog on the market, combining high speed with high resolution. Two working modes are possible: Start-stop and Marking on the fly. The software supports vector and raster formats. You can mark stickers and hot stamped holograms.

Machine’s capabilities, demonstrates the sample of the vignette sticker. This is two part double side flexographic printed label. During the first stage, the sticker has protected by several security printing features like fine guilloche elements, micro-text and UV inks. Special retro-reflective layer with integrated security elements add security level of the product. |

At the end we have the high-protected security adhesive label for vehicle windshield. The printed layers remain between the glass and the base material and are not accessible for alternating. Release layer, separated in parts with differnt adhesion, ensure the destruction of the graphic and the hologram by tearing off from the windshield. Puzzle cutting also complicate the unstick from the glass. |
Hot Air Drying SystemThe system prepares inlet air for the main drying process. The airflow is filtered, heated and distributed to Drying chambers. Possible are up to 4 Drying channels. Exhaust Fan collects the outgoing evaporations from the Dryers and sends them to the atmosphere. The automatic PID controllers sustain constant temperature in the Drying units. The equipment includes all necessary parts of structure for the drying process: Air Supply Blower (pos. 1) prepares high pressure air flow; |
Coating Systems for adhesive foilsThe Foil unwind-rewind system is placed in Work (Hazardous) area together with the Coating unit and the Drying chambers. Stainless steel & Aluminum construction could be custom build for any applications. The system is equipped with flameproof electrical equipment. The actuating devices and mechanisms have dust-ignition-proof construction. Control panel manages the web speed, the web tension control, the NIP air pressure, the coating parameters, emergency stop. The main substrate can be embossed holographic material or siliconized paper or foil. The coating unit applies thermo-reactive or pressure sensitive adhesive, other sub-layers. The web passes through coating unit and drying chambers. The two NIP units provide exact tension during the coating and drying. The system can be equipped with additional options, like web-guiding and slitting modules |

Mayer Rod CoatingOne of the most popular coating methods. The Mayer rod is a stainless steel rod that is wound tightly with stainless steel wire of varying diameter. The rod is used to doctor of the excess coating solution and control the coating weigh. The wet thickness after doctoring is controlled by the diameter of the wire used to wind the roll and is approximately 0.1 times the wire diameter. Rods are available in a wide variety of wire sizes to give a range of coating weights. The table below gives the wire sizes that are available and the wet thickness that can be achieved. The dry thickness is determined by the solids concentration of the coating solutions. |
