UV Special Varnishes.
Protective and Decorative UV-Varnishes
Marabu's special UV varnishes are suitable for rotary and flatbed screen printing. They enable high-gloss and matt surfaces or tactile prints. The full-surface or partial varnishing protects prints against mechanical and chemical stress.
- High gloss/matt finish or textured
- Good resistance to chemical and mechanical stress
- Fast curing
Substrates:
- Paper, corrugated paper
- Polyethylene (PE), pre-treated
- Self-adhesive PVC foil
- PET
- PVC, soft
- PVC, rigid
- Polycarbonate (PC)
- Polyester (PETG)
Industry solution for:
UVLG:
- Paper, cardboard, paste board, and plastics
UVLB:
- Paper, cardboard, pasteboard
- PE, PP self-adhesive foils, Corona pre-treated or top-coated
- Polyester PET foils, top-coated
- PVC and paper labels
UVLM / UVLS:
- Polycarbonate
- Pre-treated Polyester
- PVC
Since all the print substrates mentioned may be different in printability even within an individual type, preliminary trials are essential to determine the suitability for the intended use.

- Paper, corrugated paper
- Polyethylene (PE), pre-treated
- Self-adhesive PVC foil
- PET
- PVC, soft
- PVC, rigid
- Polycarbonate (PC)
- Polyester (PETG)
Auxiliaries:
| UVV3 | Thinner | 1 - 3 % |
| UR3 | Cleaner (flp. 42°C) | |
| UR4 | Cleaner (flp. 52°C) | |
| UR5 | Cleaner (flp. 72°C) |
Ink adjustment:
- Good chemical resistance
- Good rub and abrasion resistance
- Fast curing
Drying:
A UV-curing unit with a mercury lamp (80-120 W/cm) cures the varnishes at a belt speed of 20-35 m/min.
UVLB:
The UVLB 1 and UVLB 2 varnishes are highly reactive and have very fast curing properties. A UV drying unit with one or two medium pressure mercury vapour lamps (150-200 W/cm power) cures the varnishes at a belt speed of 15-50 m/min.
UVLM / UVLS:
A UV-curing unit with a medium pressure mercury lamp (80-120 W/cm) and a belt speed of 15-25 m/min will cure these UV varnishes. For the structured varnishes the use of nitrogen UV-dryers is not necessary.
The curing speed of the ink is generally dependant upon the kind of UV-curing unit (reflectors), number, age, and power of the UV-lamps, the printed ink film thickness, colour shade, substrate in use, as well as the printing speed. All UV varnishes are post-curing varnishes which will achieve their final adhesion and resistances after 24 hours. The ink film has to withstand a cross-cut tape test after having cooled down to room temperature.
Printing parameters:
All commercially available capillary films (15-20 µm) or solvent resistant photo emulsions and combined stencils can be used for UV inks.
For regular overvarnishing (UVLG) we recommend to use very fine mesh counts like 150-27 to 185-27 threads (1:1 plain weave) in order to achieve a thin ink film. The varnishes can also be printed with a thicker mesh, up to 120-34 threads.
For UVLM / UVLS we recommend a mesh count between 120-31 and 150-34 threads (plain weave). A uniform screen tension is most important to receive an even finish.
UVLB 1 is best suited for rotary screen printing fabrics such as Gallus Screeny® Type BZ and Stork Screens Rotamesh® RM 75 with 40 % open area. Ink layer thicknesses of 150-220 µm are possible to print.
UVLB 2 is suitable for flat bed screen printing. Fabrics of 32-70 to 40-80 threads/cm can here be used. By using the corresponding stencil technology (EOM 160-190 µm), ink layer thicknesses of 150-220 µm max. can be printed.
