- Suggested Uses
The 04 Series is recommended for use on PVC (Container and flat sheet * Note pg. 4), static cling vinyl, pressure-sensitive vinyl’s, many polyesters (print treated and top-coated) and some bookcloths. The 04 Series inks also work on some ABS materials. It is the responsibility of the end user to pretest all substrates with Norcote® products prior to use in production.
- Printing Recommendations
All inks should be thoroughly mixed prior to use. Inks are supplied at print ready viscosity for most applications. If adjustment is needed the 04-070 Thinner or 04-049 Overprint Clear can be used to thin the ink. Do not microwave this product.
Mesh
A mesh count of 305-355 threads per linear inch (120-140 cm2) low elongation, monofilament polyester is suggested. Tension should range from 18-25 N/cm2 on a rigid frame.
Stencil
All direct emulsions and thin capillary films (15-25μ before application) compatible with UV inks are acceptable.
Squeegee
A sharp 80 shore durometer polyurethane squeegee is preferred. Inks can be printed with durometers ranging from 60-90 as well as dual durometer squeegees.
Curing Parameters
Norcote® 04 Series inks cure only when exposed to UV light of the proper wavelength. Curing speeds depend on several factors including ink film thickness and the energy level of the
lamps. Ink should be cured immediately after printing.
Curing Equipment:
04 Series inks are fast curing and work well with one 300 watts/in (120 watts/cm) or two 200 watt/in (80 watts/cm) focused medium pressure mercury vapor lamps with
millijoules (mJ) and (mW) of: 200 mJ/cm2 @ 600 + mW/ cm² minimum for most colors and clears 300 mJ/cm2 @ 600 + mW/ cm² minimum for opaque colors (blacks, whites, tans, grays, metallics, etc.). The 04 Series inks will cure up to 100 feet per minute (30 meters per minute) with most focused UV curing units.
Screen Cleaning:
Most conventional solvent cleaners work well. Alcohol based solutions must be avoided as they break down the emulsion. Norcote recommends Press Wash 110 (flash point 113° F), 140 (flash point 140° F) or NSW-824 (flash point 150° F). These products are used for cleaning ink off screens during on press color changes or before storing the screen. They work well when removing ink from squeegees, flood bars and other equipment. Contact us for packaging options.
Coverage:
Approximately 2,500 square feet per gallon (230 square meters per gallon) depending on printing variables affecting ink film thickness and coverage.
Mixing:
All Norcote® 04 Series colors are intermixable. The 04 Series inks may also be mixed with the 09 Matte Series inks to achieve a wide range of gloss levels.

Adhesion:
The 04 Series is a nonvisual post-curing system. Although further cross-linking occurs up to 24 hours later, the 04 Series inks should pass a crosshatch tape test, (ASTM
#D3359-97), after exiting the curing unit and cooling to room temperature. Maximum chemical and abrasion resistance and adhesion will be attained after 24 hours. The use of 800 Initiator is needed for proper adhesion.
Intercoat Adhesion:
04 Series inks intercoat adhesion is very good. Although loss of intercoat adhesion is difficult, it should be monitored throughout the production run especially when printing 3 or more passes. Use of additives may adversely affect intercoat adhesion.
Weatherability:
Weather resistance is subject to conditions of use. Consult the Technical Service Department prior to use for information regarding weather resistance and weatherable applications of the 04 Series inks.
Heat-Sealing/Embossing:
The 04 Series inks are formulated specifically to produce excellent results under controlled heat-sealing conditions. To obtain acceptable results the 04 Series inks must pass a crosshatch tape test, (using 3-M 600 tape) before heat sealing or embossing. Highly pigmented (opaque) inks and inks with special effects pigments may not heat-seal
or emboss well. Radio frequency heat-sealing or high stress embossing of metallic ink is not recommended. For further details contact the Norcote® Technical Service Department.
Chemical Resistance:
The 04 Series inks have been exposed to a variety of chemicals to determine chemical resistance. The 04 Series has proved to be resistant to most common chemicals when properly cured.
Metallic Colors:
Most metallic pigments work well with the 04-000 Clear for Powders. Ability to cure a suspension is related to pigment load and UV exposure. Select mesh with openings large enough to transfer the metallic pigments of choice; generally a mesh count of 305 threads per inch (120/cm) or lower is required. Metallic pigments will
reduce the shelf life of 04 Series ink mixtures. RECOMMENDATION: Mix only enough metallic ink for one day.

Safety & Health
- Precautions
Avoid direct contact of ink with skin and clothing. If contact occurs, wash affected area with warm soapy water and dry thoroughly. If eye contact occurs, irrigate the area with water for 15 minutes and consult a physician.
Storage & Handling
- Storage & Available Warranties
All UV 04 Series inks should be stored in tightly closed, black polyethylene containers in an area with the temperature not to exceed 90° F (32.2° C). Avoid direct sunlight and indirect white light. Excess ink from print runs should be stored in separate containers to avoid contamination and is not covered under any warranty. When stored under these conditions, Norcote warrants the Products shall be free from defects in material and manufacture for a period of one (1) year from the date of sale for the 04 Series standard inks, with no additives, and for a period of one (1) month from the date of sale for any custom color containing Day Glo® JZB or T-Powder. Norcote will not warrant any custom colors containing metallic pastes or any inks intermixed with competitor products. Any warranties provided will be limited to the price paid for the actual products used which give rise to the warranty claim.
