The invention of electromechanical engraving by Dr. Rudolf Hell some 50 years ago heralded the era of etch-free industrial printing form manufacture using the HelioKlischograph – a prerequisite for today’s fully automatic form manufacture. Multi-channel engraving makes this method even more cost-efficient. Thanks to high engraving frequencies of 8 and 12 kHz, high-resolution and quality-optimizing engraving processes, and intelligent software algorithms, high speeds are now achieved with uniform results across the entire format that can be reproduced at any time.
The full scope of gravure imaging
Direct laser engraving
Contactless direct engraving with no tool wear using Cellaxy is the optimum method for the high-resolution transfer of text, linework, and intaglio images to gravure forms and of three-dimensional structures onto embossing rollers. Generally speaking, the depth and edges of the cells and cell walls can be designed very effectively for emptying purposes, because this method offers a far greater choice of aspect ratios than electromechanical engraving.
Flexible packaging – versatile and future-proof
Gravure’s largest and most diverse market segment has to meet exceptionally strict quality criteria for conveying the brand and product image, but optimum organization and maximum efficiency are also increasingly important given the time-critical production requirements. The high speeds of electromechanical engraving machines and the perfectly coordinated processes eliminate bottlenecks – the key criterion for our customers!
Tobacco – the supreme challenge in packaging printing
The tobacco industry expects its packaging to convey a strong message and be instantly recognizable, with a great deal of textured finishing and complete sensory neutrality. This is important, because the tiniest design details and the packaging’s quality carry key brand messages. The HelioKlischograph and Cellaxy complement each other perfectly, ensuring high-resolution line engraving, top-quality linework, and large volumes with directly lasered embossing cylinders in full 3D.
Decoration – the perfect look with the narrowest of tolerances
Decorative printing was the first market segment in the printing industry to apply extremely stringent quality requirements in terms of color reproduction. This is because the narrowest of tolerances are vital if production runs of imitation wood grains, wallpaper, and floor coverings are to be reproduced at will. And when it comes to tissue and wrapping paper, the main focus with cylinders both large and small is on delivering the very high ink transfer volumes that can only be achieved with large engraving depths and must work for all kinds of ink systems.
Illustration printing – source of many innovations
Publication gravure with its large cylinder widths and critical throughput times was once the nerve center of modern rotogravure. This gave rise to numerous innovations that have now become a vital part of packaging and decorative printing.
