APPLICATION OF WINK WATERBASE INK

Conversion:

Drying times are somewhat slower than conventional solvent base inks. The key requirement is higher air flow in the dryer. Run ability is good, but care should be taken not to allow ink to dry in the screen, as dry waterbase inks do not redissolve in wet ink as solvent based inks do. Conversion from solvent base system entails a very short learning curve.

Applications:

Rigid PVC, vinyl coated paper, styrene, treated polyester, metals and foils.

Stencil Emulsions:

There are several good resists designed for water base inks in the market place. The usual cause of stencil failure is improperly dried emulsion before washout. Stencils can be removed by using commercially available paint stripper and a high pressure washer. It is important, however, to follow manufacturers directions carefully.

Screens:

We recommend the use of monofilament polyester screen material. For mass tone printing a mesh of 220 or higher should be used. Meshes of 195 or lower should be used with lustre pigment inks such as WINK Fine Gold Eagle and WINK Fine Silver ink.

Storage and Handling:

WINK series ink should be stored in a cool place for maximum shelf-life. But as with all inks, they must be allowed to return to ambient press room temperature before running.

Mixing:

Although WINK series inks are designed to remain dispersed, it is best if they are mixed for a short period of time just before printing.

Printing:

WINK series inks are formulated to be used as supplied, but in instances where viscosity adjustments are needed, WINK Thinner T100 can be used and in instances where fine detail is needed or the press room is exceptionally dry or warm WINK retarder R200 can be used.

Drying:

WINK series inks are fast drying and will dry in a few seconds in a forced air oven at 170-200oF.

Clean-Up:

Screens can be cleaned with tap water (inks must be kept moist and not allowed to dry in screens). A spray bottle filled with cleaner PM13 should be used to keep ink from drying during the short press stoppages. If screen images are to be re-used, screens should be washed carefully and dried, before storing.
