  • How to determine a printable optically clear film outdoor durability?

    Printed optically clear
    Printing on optically clear using certified ink with vertical installation (The face of the graphic is ±10° from vertical) and having sunlight exposure of no longer than 8 hours, it is recommended to apply another layer of optically clear film itself as laminates to maximise its outdoor durability for up to 2 or 3 years, and provide adequate protection against scratch, abbration and mild chemical spill.

    Graphic and material durability is largely determined by the climate and the angle of exposure.  Graphic and materials used in temperate zone would extend its life time for another 2 to 3 years due to lower UV intensity.

    Illustrative lab durability simulation test against actual outdoor can be compared using these parameters:

    Q-Lab QUV is most freqently used testing equipment and using two types of UV exposure lamps:
     *  UVA-340 lamps for 120hr considered as 6 months outdoor in temperate zones
     *  UVB-313EL lamps for 500hr considered as 6 months outdoor in tropical zones

    None of McSign products are particularly made to be used in the polar zones.

    Printed graphics with lamination and protection

    Using certified ink with vertical installation (The face of the graphic is ±10° from vertical) and having sunlight exposure of no longer than 8 hours, using monomeric laminates with monomeric print vinyl will further enhance its durability for up to 1 year and provide adequate protection against scratch, abbration and mild chemical spill.  Using polymeric laminates with polymeric print vinyl as a system will further enhance its durability for up to 2 or 3 years and provide adequote protection linke normal laminates.

  • What types of release liners can be offered?

    PE liner
    · A standard 130gsm Japanese imported white kraft paper coated with single side PE (1PE) liner for general purpose cut graphics, lamination and digital printing
    · A standard 130gsm Japanese imported white kraft paper coated with double side PE (2PE) liner for a good lay-flat property cut graphics, lamination and digital printing
    · A heavy 170gsm Japanese imported white kraft paper coated with double side PE (2WPE) liner for premium lay-flat property, best recommended for digital and screen printing

    Air-release liner
    · 130gsm / 170gsm PE (2EB/2WEB) kraft air-release / bubble free liner for cut graphics and digital printing

    CCK
    · 140gsm white clay coated kraft (CCK) paper liner for premium lay-flat property cut graphics and digital printing

    PET liner
    A good PET liner offers smooth adhesive surface quality and clarity, slip resistance treatement on the back
    · 36u polyester (PET) clear filmic liner
    · 50u polyester (PET) clear filmic liner
    · 75u polyester (PET) clear filmic liner
    · 100u polyester (PET) clear filmic liner

  • What are the advantages of using different release liners?

    · Cost effectiveness and print heating consistency – 1PE kraft
    · Lay-flat property and print heating consistency – 2PE kraft
    · Superior lay-flat property, heat resistance and cut sheet consistency – 2WPE kraft
    · Smooth and clear adhesive finish – PET liner at different thickness

  • How should I chose to use different release liners?

    · Cut graphics: standard 1PE or 2PE liners is enough for the job, chose 2PE for better stability
    · Digital printing: take standard 1PE for cost effectiveness, 2PE for lay-flat property, 2WPE for screen, UV and Latex, 2EB/2WEB for larger area when dry application is required
    · Window decoration, transparent displays: PET filmic liner is always the best choice giving best clarity
     

  • What types of face material can be offered and its purpose?

    · PVC – Most common thermal plastic, that is flexible and stretchable, requires adhesive backing, best recommended for digital sticker posters and screen printing, lamination, cut graphics, window deco, vehicle wrap, wall mural, masking, sandblasting etc.
    · PP –  Normally referred to as a synthetic paper, it should be top coated for digital and screen printing, it can be used alone as a poster paper, or with adhesive backing.
    · PET – Most rigid and lay-flat material, it can be clear or opaque as a pop up, it should be top coated for digital, screen and UV printing.  Special purpose like anti-graffiti requires surface treatment.  It can be metallized and coated with adhesive backing for cut graphic purpose.
    · Photo paper – digital printing
    · Fabric – wall mural
