APPLICATION OF WINK™ WATERBASE INK (2-PK) FOR METALLIC EFFECTS

Conversion | Applications | Screens | Mixing | Printing | Drying | Clean-Up

Conversion:

Drying times are somewhat slower than conventional solvent base inks. The key requirement is higher air flow in the dryer. Combination air knife/evacuation with IR is particulary effective. Runability 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. See recommended mesh table for each pigment used.

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. Once mixed, inks should be run immediately any unused ink should be discarded. Do not mix other materials with theWINK (2-PK) kit as unwanted reactions may occur.

Mixing:

WINK (2-PK) systems are designed to be added just before use and mixed for a short period of time just before printing. For a 5 gallon batch, place approximately 1/5 of the liquid portion (1 gallon) in a container of about five gallon capacity. Place on Cowles type mixer and increase mixer speed until a vortex develops. Slowly add pigment paste into the vortex. Add only as fast as it can be drawn in. After all the pigment paste has been added, scrape the sides of the mixing container with a spatula. Continue mixing until all the paste is thoroughly premixed and there are no clumps of pigment. Add remaining 4 gallons of liquid wink ink. Mix until thoroughly dispersed.

Printing:

WINK (2-PK) series inks are formulated to be used as a supplied kit, 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 170-200°F.

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 ammonia, water, or WINK Screen Cleaner NA! should be used to keep ink from drying during the short press stoppages. If screen images are to be reused, screens should be washed carefully and dried, before storing.
