- Range
The LIS 4-clr process shades have increased density values and are therefore especially suited for printing onto backlit objects. By using the 9 SR Pantone® basic shades together with LIS 070, LIS 073, and Print Varnish LIS 910, more than 1000 color shades of the Pantone® Color Formula Guide can be mixed. Highly fade-resistant shades fulfill high demands for long-term outdoor resistance. If printed onto the top side of the material, we recommend a full-area over-varnishing with the UV-Absorber Print Varnish LIS 911. Owing to their comparatively good light fastness, the basic shades 033/036/055/056/ 058/059/067/068/070/073 should be used for combinations with the highly lightfast color shades 720 - 735. If printed onto the reverse side of the substrate, the brightened white shade LIS 971 with an optimized degree of white is available for vertical or backlit illumination. Furthermore, there is one shade available for printing onto polystyrene for chalk-writeable boards (fabric recommended 77-55 to 100-40). All shades are intermixable. Mixing with other ink types or auxiliaries must be avoided in order to maintain the special characteristics of this ink. All basic shades are included in our MarabuColorFormulator (MCF). They build the basis for the calculation of individual color matching formulas, as well as for shades of the common color reference systems HKS®, PANTONE®, and RAL®. All formulas are stored in the Marabu-Color Manager software.

- Shelf LIfe
Shelf life depends very much on the formula/ reactivity of the ink system as well as the storage temperature. The shelf life for an unopened ink container if stored in a dark room at a temperature of 15 - 25 °C is: • 3 years for LIS 191, 193 • 3.5 years for all other LIS standard products Under different conditions, particularly higher storage temperatures, the shelf life is reduced. In such cases, the warranty given by Marabu expires.

- Characteristic
Very good mesh opening for standard and 4- color process shades, i.e. printability of LIS is very simple and easy. LIS is highly suitable for flat-bed or cylinder printing machines but can also be processed in manual printing or on semi-automatic machines. Printing speed up to 2500 prints / hour. Ink Adjustment The ink should be stirred homogeneously before printing and if necessary during production. Drying Physically fast drying, at 20 °C air temperature to be overprinted within 4-6 min, at 40 °C in a tunnel dryer stackable after 20-30 sec. Drying speed and block resistance are reduced by about 20 % when overprinting. The times mentioned above vary according to the substrate, the ink film thickness, drying conditions and the auxiliaries used. Fade resistance Pigments of excellent fade resistance (blue wool scale 7-8) are used for the Libra Speed LIS basic shades. Provided a professional processing and max. addition of 50 % varnish or white to the standard shades, all basic shades are suitable for an outdoor use of up to 3 years referred to the middle European climate. A full-area coating with Print Varnish LIS 911 onto the whole surface will extend the possible outdoor exposure time to 4 years. When using the highly fade-resistant shades of the 7xx series, outdoor resistance can be increased to max. 5 years if placed vertically and referred to the middle European climate, north of the fortyfifth degree of latitude. In countries with higher exposure to sunlight (between the 40th parallel north and 40th parallel south) the outdoor resistance decreases. Due to the required brilliance, the PANTONE® shades are more transparent than the basic shades and do, therefore, not achieve the above mentioned high fade resistance. The pigments used are resistant to solvents and plasticizers. Stress resistance After proper and thorough drying, the ink film exhibits an outstanding adhesion as well as rub, scratch, and block resistance and can also be vacuum-formed. LIS exhibits a normal chemical resistance of 20 double rubs with alcohol and other usual cleaners (e. g. window cleaner). For a higher rub resistance to dry abrasion of the color shades, we recommend to overcoat with Print Varnish LIS 910 or LIS 911. For a higher chemical resistance, the color shades can be over-varnished with Print Varnish SR 910 or a suitable UV-curable varnish.
