GBS - One Part, Universal Container UV Ink
Gloss Bottle GBS is a one-part screen ink developed with the needs of the container printer in mind. This is the only UV ink series with adhesion to plastics including, HDPE, LDPE, PET, PVC, and PP without the use of adhesion promoters or catalysts. The ink exhibits excellent flexibility for squeeze tests on thin walled LDPE, yet it maintains a durable chemical and water resistant surface which withstands the most stringent product tests. The unique rheological properties of GBS presents smooth printability with minimized drip through and reduced cleanup time.
The GBS Series is offered with an unmatched blending system. All colors used in the NSC’s Color Matching System (CMS) are 20% stronger than current industry standards. This high density system provides the most vibrant, opaque colors and allows the printer to use higher mesh counts to reduce ink usage thereby saving money.
• Unequaled, straight from the can adhesion to poly containers
• Does not require flame treatment for PET or PVC adhesion
• Highly flexible for thin walled containers
• Superb water and full chemical resistance after 24 hours
• Fast, tack free-cure for running high line speeds
• 20% stronger CMS colors for vibrant, sharp hues
GBS Series exhibits excellent adhesion to a wide range of container materials. For best results the following require a flame treatment prior to printing: high density polyethylene, low density polyethylene, and polypropylene. No flame is required for PVC and PET bottles. To determine suitability of the product for the intended use, a pretest prior to production is advised.
CURING: GBS will cure well when printed through 305-380 (120-150cm) plain weave polyester mesh. A minimum of 125 mJ is required to cure standard colors. This optimal cure window is generally achieved with one 300 watt per inch mercury vapor lamp at press speeds up to 70 containers per minute.
Adhesion should be a minimum of 95% from curing unit with final adhesion developing within four hours of initial polymerization.
If a loss of gloss or adhesion due to insufficient cure is noticed, the use of 5-10% GBS Mixing Clear will increase light penetration and improve cure in opaque colors. Mix 5-10% GBS Overprint Clear with white inks to increase cure rate.
PRINTING: Mix well prior to every use. Although GBS has been supplied in press ready condition, this system may be reduced up to 10% with GBS Thinner for special viscosity adjustments.
Care should be taken to print the ink at the optimal temperature of 70°-90°F (21°- 27°C). Cool ink will have heavier viscosity and will not flow properly whereas excessively warm ink will be lower in viscosity resulting in poor definition and decreased opacity.
SQUEEGEE: 70-90 durometer polyurethane blade is recommended.
COVERAGE: 3200 to 3600 square feet per gallon for film deposit of .40 to .60 mil.
CHEMICAL RESISTANCE: To be announced.
WATER RESISTANCE: GBS has passed all laboratory conducted water immersion/wet flex tests. Printed bottles were tested immediately as well as after a 24 hour ‘post cure’ period. This period, between curing and testing, provides the ink film and substrate time to stabilize, improving adhesion properties.
METALLICS: A superior two part system comprised of GBS Metallic Mixing Clear and the proper metallic paste has been developed. The increased viscosity of MMC helps insure a good particle suspension and our new metallic technology provides unparalleled premix shelf life and stability. The recommended mixing ratios are: 12% silver paste, 28% gold paste (by weight) to achieve the standard metallic colors.
For optimum coverage and opacity, 280-305 (110 – 120cm) plain weave monofilament mesh is recommended. When overprinting metallic inks, best results are achieved with the addition of 5% 1534 Adhesion Promoter.
STORAGE: Care should be taken to store ink in tightly closed containers located in a cool (60 degree F to 80 degree F(15 degree to 27 degrees), dark place. After long production runs excess ink from the screen should be properly disposed. With suitable conditions, the ink is expected to have a shelf life of approximately 12 months from the date of manufacture.
PRECAUTIONS: Read the material safety data sheet prior to processing. It contains instructions for precautions when processing, handling, and storing inks, as well as first aid. If ink comes in contact with skin, wipe ink off with a clean, dry cloth (do not use solvent). Wash and rinse the affected area with soap and water.
PROCESS PRINTING: For superior halftone reproduction, Gloss Bottle New Rheology halftones are available. Additional control of densities may be achieved with the use of GBS Halftone Extender Base. For best results, 355 (140 cm) plain weave mesh or finer and a smooth, thin stencil coating should be utilized with four color process printing. GBS Halftone Yellow 1.10 GBS Halftone Magenta 1.75
