Embodiment 1
[0026] Example 1a - male mold, synchronous effect
[0027] The foil production process is based on rotary intaglio printing. A wood-like design 2 is applied to a carrier 1 made of paper foil. The design is transferred to the band by pressing the band against the printing cylinder with special rollers coated with rubber of sufficient hardness. The roll is dipped into a rotating toner container with a feed roller. Excess paint is removed by adjustable scrapers on the printing cylinder. The coated web is then dried in a hot air chamber and then transported to the next printing unit. The carrier passes through three printing stations. The process is carried out using water-soluble paint.
[0028] The next step is the application of a protective layer 3 on the carrier 1 . This is achieved with a special intagliocylinder, which is used to apply the primer 3717.212. The roller applies approximately 6g / m 2 The primer, which is similar to paint, hardens at a temperature of 14...
Embodiment 1b
[0046] Example 1b - male mold, asynchronous effect
[0047] The design and the protective layer were applied to the carrier 1 consisting of paper foil in the same manner as presented in Example 1a.
[0048] The next step is to apply the first coat of EB Coat 4 by the 3WS coating system. In this part of the process, Coat A has the following composition:
[0049] - FL 27692 - 1 copy
[0050] -FLE 27800 - 0.1 part
[0051] - FZ 2711 - 0.07 parts
[0052] - FZ 2720 - 0.15 parts
[0053] The grammage to be obtained is 8g / m 2 The coating was exposed to an excimer lamp, and then a preliminary polymerization process (gelation) was performed in an EB generator of PCT Corporation. The generator parameters are set as follows:
[0054] - Dose 5kGy
[0055] - High voltage 100kV
[0056] The obtained surface has a gloss of less than 6° measured at a 60° geometry.
[0057] The carrier strip is then transported to a station with gravure cylinders with asynchronous patterns adapted...
Embodiment 2
[0065] Example 2a - Female mold, synchronous effect
[0066] Design 2 and protective layer 3 were applied to carrier 1 consisting of paper foil in the same manner as presented in Example 1a.
[0067] The next step is to apply the first coat of EB Coat 4 by the 3WS coating system. In this part of the process, Coat A has the following composition:
[0068] -FLE 27800 - 1.0 copies
[0069] - FZ 2720 - 0.15 parts
[0070] The grammage to be obtained is 8g / m 2 The coating was exposed to an excimer lamp and then underwent a preliminary polymerization process (gelation) in an EB generator of the PCT company. The generator parameters are set as follows:
[0071] - Dose 4kGy
[0072] - High voltage 100kV
[0073] After this stage, a surface is obtained that is characterized by a gloss of 1-2° measured at a geometry of 60° and a gloss of more than 8° measured at a geometry of 85°.
[0074] The next step in the fabrication process is to apply the synchronization structure to di...
