Technical Data Sheet Screen Printing Ink for PVC self-adhesive Glossy, medium opacity, fast drying, foils, rigid PVC, acrylics, polystyrene, block resistant, flexible, low odour, very ABS/ SAN, soft PVC, polycarbonate, pa- good mesh opening, vacuum-formable per, pasteboard, cardboard Field of Application Substrates Libra Print LIP is suited to print onto: • PVC self-adhesive foils • Rigid and soft PVC • Polystyrene (PS) • ABS/SAN • Acrylics (PMMA) • PETG • Polycarbonate (PC) • Paper, pasteboard, cardboard • Wood 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. Field of use Libra Print LIP is highly suitable for the production of PVC-stickers, advertising panels, displays, ring binders, book covers, straps, and letterings of every kind. To decorate tarpaulins made of PVC, we recommend our tarpaulin ink Maraplan PL instead of LIP. LIP is vacuum-formable except for the 4x9 process shades. LIP can also be processed with a spray gun, but preliminary trials are necessary for this process. In order to avoid surface irregularities, we recommend to filter the thinned ink (25 pm screen) before processing. Characteristics Printability of the LIP is very simple and easy thanks to the very good mesh opening for standard and 4-colour process shades. LIP can be processed by hand printing, with semi-automatic machines up to fully automatic machines. LIP is suited for printing speeds up to 1400 prints/h (single prints). The flow characteristics of LIP have been adjusted in such a way that the ink does not drip through the mesh when the machine is standing still or run together in angle opening machines. Gloss level Libra Print LIP is glossy and has the following measured gloss values (60° angle). Value 100 stands for high gloss, while value 1 stands for deep-matt: Basic shades: 50 - 60 gloss units Printing Varnish LIP 910: 70 - 80 gloss units 4-colour process shades: 25 - 35 gloss units If a higher gloss is required, we recommend to overcoat with Printing Varnish LIP 910. Opacity The LIP colour shades are brilliant with medium opacity. To increase the ink’s opacity on dark substrates, it is possible to add up to 15% of Opaquing Paste OP 170. Ink Adjustment The ink should be stirred well before printing. Drying Physically fast drying, at 20 °C air temperature to be overprinted within 10-15 min, at 50 °C in the tunnel dryer stackable after 30-40 sec. Drying speed and block resistance are reduced by about 20 % in overprinting. With high dryer capacity and good ventilation provided, the drying temperature can be reduced to 40 °C for less material distortion. Marabu GmbH & Co.

Technical Data Sheet The times mentioned above vary according to the substrate, the ink film thickness, drying conditions and the auxiliaries used. An extended drying time is necessary if Plasticizer WM 1 has been added to the ink. Fade resistance Depending on the colour shade, pigments of good to excellent fade resistance (blue wool scale 6-8) are used in the Libra Print LIP range. All standard and 4-colour process shades are therefore suitable for outdoor use for two years if placed vertically and referred to the middle European climate. Precondition for this is the appropriate and professional...

Technical Data Sheet S 292 High Gloss Rich Pale Gold 10-20% S 293 High Gloss Rich Gold 10-20% These metallics are to be added to LIP 910 in the recommended amount, whereat the addition may be individually adjusted to the respective application. We recommend preparing a mixture which can be processed within a maximum of 8 h since metallic mixtures usually cannot be stored. Due to their chemical structure, the processing time of mixtures with Pale Gold S 184 and Copper S 186 is even reduced to 4 h. Owing to the smaller pigment size of Metallic Pastes it is possible to work with finer...

Technical Data Sheet Libra Print LIP without considerably influencing the chemical and dry abrasion resistance. OP 170 is not suitable for white shades, and should not be used for prints that will be exposed to more than 2 years outdoor application. For spray varnishing, our Quick Thinner PSV should be used (by adding approx. 40 %) after preliminary trials. The cleaners UR 3 and UR 4 are recommended for manual cleaning of the working equipment. Cleaner UR 5 is recommended for manual or automatic cleaning of the working equipment. Printing Parameters All types of commercially available polyester fabrics...
