ULTRASTAR

With ULTRASTAR inks, metallic effects can be achieved previously only seen with metallized substrates or transfer foils.

Metallic and mirror-like ink that offers:

  • Brilliance – Metallic inks that offer the allure of cold foil and/or hot foil stamping
  • Sustainability – Less waste, only use metallic where you need it
  • Savings – Reduced cost and faster production
  • Versatile – Designed for both absorbent and non-absorbent substrates

Specific to Front-End Coaters

What is ULTARSTAR?

ULTRASTAR is our brand for Mirror Effect inks. It combines two words: ULTRA means exceeding, while STAR stands for luster = exceeding luster effect. These are metallic inks for gravure, flexo and screen printing offering extraordinary chrome effects within the graphic arts industry.

ULTRASTAR also works as an alternative to metallized substrates.

What are the benefits of ULTRASTAR?

  • Mirror Effects
  • Chrome-like effects
  • Alternative to metallizes substrates
  • For surface printing
  • For reverse printing
  • For foil substrates as well as paper and carton
  • Printing ULTRASTAR on the spot is cheaper than overprinting of metallized board
  • Printing of roughly 15% of a design with ULTRASTAR effect is cheaper than using hot foil stamping
  • ULTRASTAR simulates the effects of metallized substrates

What types of printers can use ULTARSTAR? For what substrates?

Gravure:

  • Printers with equipment for solvent gravure inks can use ULTRASTAR.
  • Printers of labels (wet glue labels or pressure sensitive labels.
  • Printers for tobacco packaging. Printers for food packaging.
  • Printers which can use the ULTRASTAR effect surface or reverse printed onto film.

ULTRASTAR is also for surface printing on paper and board; the use of a primer improves the ULTRASTAR mirror effect.

Flexo:

  • Printers with equipment for solvent or UV curing flexo units.
  • Printers of labels (wet glue labels or pressure sensitive labels).
  • Printers who have a UV curing lacquer unit at the front or end of an offset press.
  • Printers with a UV curing coating Unit.
  • Printers for food packaging.

Screen:

  • Printers with equipment for solvent or UV curing screen units.
  • Printers of labels (pressure sensitive labels) and such doing finishing offset printed carton boards.

How is ULTARSTAR made?

ULTRASTAR products are based on very thin VMP pigments. These pigments are specially produced: Onto film is a clear layer printed – we call it “release coat”. Aluminum is under vacuum evaporated and deposited onto film. In between the aluminum and the substrate is the release cote. The substrate goes into a “stripping bath” of Acetone. The release coat is dissolvable in acetone. The result is substrate and a slurry of thin aluminum layer in a solvent bath. By stirring the aluminum slurry, the particles result into a defined particle size distribution. By solvent exchanging, the very thin METALURE® particles are available in ethyl acetate or ethanol.

This dispersion can be used to formulate solvent based ULTRASTAR inks.

For UV curing ULTRASTAR effects there is an additional production step: ECKART stabilizes the METALURE® pigments in acrylate or photoinitiator.

Why are VMP Pigments superior?

VMP pigments give a broad variety of mirror-like effects: light and dark, bright and chrome-like. VPM Pigments are thin, like sheets of papers, to formulate an ink it needs only little amount of pigment to get an extraordinary brilliance with excellent coverage.

Why are VMP Pigments suitable for inks?

VPM pigments can be the base of all kind of printing ink formulations and for any technology. VMP pigments in combination with ECAKRT’s stabilization technology are suitable for UV curing systems.

Why sustainability is important to printers?

Raw material cost is expensive. Energy is expensive. Waste is expensive. Maculature is expensive. Smooth running processes reduces waste, energy and cost.

Why is sustainability important to ECKART?

ECKART is optimizing production processes to save energy. ECKART is member of EuPIA and follows their guideline. ECKART wants to be a partner with ink manufactures and lead raw material for metallic effect into the future. ECKART takes responsibility for all their products and especially for GMP manufactured grades: FPG – Food Packaging Grades.
