Dry offset printing is ideal for decorating open containers, metal drink and aerosol cans, and polymer cups and tubes. Elastomer offers many advantages in this process. The surface tension of elastomer and blanket is coordinated, which leads to excellent ink transfer. The low tendency to swelling extends the service life of the printing form. The ultra-fine laser spot of the fiber laser engraves with a previously unattainable resolution. Careful use of infinitely variable undercuts results in much lower dot gain. Elastomer printing forms for IDF machines do not require a separate sandwich structure. The PremiumSetter is much more productive than conventional direct engraving systems.
The diverse range of applications for the PremiumSetter
Dry offset for container printing
Coating applications enhance sheetfed offset
Surface finishing can hugely improve the appeal of packaging for cosmetics, foodstuffs and toys as well as publicity materials. Sheetfed offset enhanced with a flexographic coating unit offers a varied range of surface finishing options. Here, too, elastomer delivers many benefits. The finest elements can be reproduced, and larger areas can be coated evenly and with excellent edge definition. Short process times ensure fast availability of the printing form. Elastomer printing forms are also much more cost-effective than conventional printing plates.
Hygiene, wrapping paper, ruled paper
Ruled paper, napkins, wrapping paper, diapers, and other hygiene products are frequently printed in large-format and continuous processes. This is where PremiumSetter technology unlocks the benefits of high-resolution direct engraving. Elastomer printing forms last longer, particularly on coarse print substrates. The ultra- fine laser spot of the fiber laser enables finer screens to be used than is usually the case with CO2 lasers. Ink transfer is excellent, and embossing rollers can also be engraved.
Flexible packaging, especially with flexographic printing, is becoming an attractive option for more and more brand owners. High-resolution direct engraving using PremiumSetter technology delivers printing results that are on a par with gravure or offset printing. Digital control options for printing form parameters and the properties of elastomer combine to deliver longer service life and maximum reproducibility. High print densities ensure out- standing results for white backgrounds, for example. Elastomer sleeves offer a significant cost advantage over photopolymer sleeves and are also much faster procured and provided in a press-ready condition.
