Discription:

UVN-MP is an NVP-Free, fast curing, single-package, multi-purpose ink system formulated for screen printing on a wide variety of substrates

Characteristics:

UVN-MP is suitable for printing on the following substrates: pressure-sensitive vinyl, rigid vinyl, styrene, ABS, polycarbonate, most pretreated potyolefins, coated paper stocks and acrylics.

Pigments/Liightfastness:

UVN-MP inks are available in C-Mix 2000 blending colors and 4 color process shades. If the basic ink shades are mixed with high content of white or clear, lightfastness of the prints are reduced.

Modification:

UVN-MP is a single-package ink which does not require the use of any additives under normal printing conditions. The following additives are available for modification:

ST-370	Cure Accelerator	1-5%

ST-374	Adhesion Promoter	1-3%

ST-375	Hardener	5%

ST-376	Thinner	3-10%

ST-377	Flow Promoter	1-2%

ST-378	Light Stabilizer	3-5%

	Chemistry: UV

	1 or 2 Pack: 1 Pack

	Color System: C-Mix 2000

	Dry/Cure Time: UV 250-350 mj/cm

	Durability: 12-24 Months

	Finish: Gloss

Bronze Inks:

For bronze prints, UMP-E50 can be mixed with bronze paste and powders B75 to B79. Mixing ratios are as follows:

Gold Bronze paste: UMP-E50 = 1:3-4

Silver Bronze paste: UMP-E50 = 1:3-4

Gold and silver bronzes are metal particles which react with the pH-acidic components. Therefore, mixed bronze inks should be processed quickly. Shelf-life is limited to 24 hours after mixed. Depending on the bronze used, oxidative reactions may cause color changes (darker) or thickening of the mixed system due to catalytic effects. Although the binders contained in UV inks generally have good stability, they cannot be delivered pre-mixed with metallic pigments for the reasons above. Mixed bronze powders have a better storage than mixed bronze pastes. When printing metallic color shades, a 305/in. polyester fabric is necessary for adequate passage of the metallic particles.

NOTE: Pretest all metallic blends prior to use in production.

Screen Mesh:

305-420/in.(120-165/cm) monofilament polyester mesh, or finer, is suitable for processing. It is possible to use coarser fabrics; however, the curing parameters must be adjusted for sufficient cross-linking of the increased ink film deposit.

Squeegee:

Sharp urethane squeegee of approximately 75-85 durometer

Coverage:

When printed through a 381/in.(150/cm) twill-weave mesh, UVN-MP will cover approx. 3000 square feet per gallon, depending on printing variables. Higher coverage can be achieved when finer mesh counts are used.

Process Colours:

UVN-MP 4 color process inks are available as high color-strength SWOP colors. UMP-TPS Transparent Base may be used to adjust density. As with all U.V. halftone printing, plain-weave mesh counts and thin stencil coatings should be used to minimize ink deposit, dot gain and other variables associated with 4 color process printing.

Storage:

All U.V. inks should be stored in closed, black polyethylene containers at temperatures below 90°F (32°C)

Health and Safty

UVN-MP is formulated to be NVP-FREE. As with all inks, gloves and safety goggles should be used when handling this product. For more complete information, refer to the relevant Material Safety Data Sheets.
