RAPIDA^®- ECO 7500

The super-fast sheet-fed offset process inks based on renewable raw materials – mineral-oil-free.

The new generations of HIT process inks (HIT: HIGHLY IMPROVED TECHNOLOGY) from the HUBER-GRUPPE are manufactured in optimized production processes. The special constituents of the process inks are matched precisely to the individual stages in the manufacturing process. The wetting medium and the finely controlled dispersion conditions have been chosen so as to ensure that the ink pigments are coated completely and in a stable manner with binder; the binder components selected specifically for these pigments actively support this wetting process. Thanks to this fresh optimization of the "HIGHLY IMPROVED TECHNOLOGY" process, the printing characteristics of the HIT process inks have been greatly improved.

The improvements in quality are to be found in areas such as the development of color intensity, gloss, rub resistance, flow behavior, damping solution tolerance, stability at high printing speeds and further processing.

The HIT technology guarantees a high level of production reliability and the best print results. The RAPIDA-ECO 7500 process inks constitute the sheet-fed offset series with the fastest absorption properties for immediate turning and rapid further processing. The RAPIDA-ECO F series is a stay-fresh variant (F = stay-fresh; example: RAPIDA-ECO-Yellow 41 F 7500). This formulation is predominantly suitable for coated stocks.

Special characteristics

• Very rapid absorption and outstanding stacking properties with minimal powder spraying.

• Ideally suited to rapid turning and quick further processing.

• High damping solution tolerance.

• Rapid adjustment of a stable ink/water balance.

• Good gloss.

• Good rub resistance.

• Superbly suited to infrared radiation drying.

• Free of mineral oil.

Fields of application

The RAPIDA-ECO 7500 process inks constitute the fastest series of sheet-fed offset inks. They are suitable for all sheet-fed offset presses and damping units, in particular for high-speed multi-color presses. Their excellent absorption and stacking properties permit immediate turning and rapid further processing, with these characteristics becoming evident above all on less absorbent printing stocks.

The RAPIDA-ECO 7500 ink series stands out due to its high color intensity and brilliancy. The pleasantly smooth, free-flowing consistency is particularly printer-friendly. Moreover, the system impresses through high dot definition and high-contrast finish. Characteristic profile of the RAPIDA-ECO 7500 process ink series.

Additives

Should it become necessary, under exceptional circumstances, to adapt the process inks to special printing conditions, additives should be used which are compatible with the highly developed binder system:
• for reducing tack on printing substrates sensitive to picking, 2 to 3% Print Oil 10 T 1405,
• to accelerate oxidative drying, MONSUN 10 S 7265.
