White Papers - UV Ink Metering
With today’s amazing innovations in plate design, ink technology, and faster press speeds, professional print shops have been able to provide more impressive end results than in years past.
Throughout the industry, white inks are notorious for being inconsistent and requiring frequent changing of doctor blades often. Weighing the cost of a doctor blade vs. the cost of press downtime is as issue printers and coaters deal with constantly. The issue with metering white inks is actually a little more complicated than just buying the right blade.
There are many ways to describe chatter: bounce, gear-marks, banding and stripes of uneven ink application on the printing field. But whatever name it goes by, the common attribute is that chatter often shows up with little or no warning once on press.
With the existing MDC Anilox Cleaner, we have succeeded in establishing a solvent-based deep cleaner for all chrome and ceramic anilox rolls in gravure and flexographic printing applications. The deep cleaning is important so that the full pick-up volume of all chrome and ceramic anilox rolls can be achieved.
In order to meet market requirements and customer needs, we have now developed a new cleaner called MDC Aqua Pure Cleaner. As the name suggests, the MDC Aqua Pure Cleaner is water-based and offers the customer a gentle and effective deep cleaning of all chrome and ceramic anilox rolls. A major advantage is that the new cleaner is non-hazardous: it can therefore be easily shipped around the world by truck, air, and sea freight. Furthermore, the new cleaner is safe on aluminum and removes all common ink and varnish contaminants.
The MDC Aqua Pure Cleaner optimally complements the existing range and enables us to enter new target markets. The MDC Aqua Pure Cleaner was launched in June 2020 and has already achieved initial sales success.
End seals are a complementary product for doctor blades. The end seals are required for the flexographic printing process in order to seal the chamber doctor blade system cleanly and to prevent the paint from escaping. Together with the doctor blades, the end seals form a necessary part of the chamber doctor blade system. Both act by contact with the anilox roller as wear parts and affect the system of ink transfer and each other. In this context, a new concept for end seals was developed. Here, the MDC End seals are divided in three different quality and price levels according to the material properties and are offered to the customers according to their running time and MDC doctor blade quality used. The three quality levels have the following designations: MDC Regular, MDC Advanced and MDC Expert.
The distribution partners are informed about all available dimensions and materials by the developed MDC End Seals booklet. The MDC End Seals Booklet is intended to serve as a tool to facilitate communication between Daetwyler SwissTec and its distributors, as well as between distributors and end users. With this concept, Daetwyler SwissTec creates a standard that helps customers out of the jungle of end seals and offers a fitting solution for MDC end seals for the already used MDC doctor blades.
The heart of the machine consists of a high-precision diamond tool, used for milling the gravure cylinders. It is in the diamond shop (also known as «Diamanti») where we develop and produce these tools. Working on the diamond tools takes years of experience and a lot of know-how.
The diamond tools are created with grinding and lapping machines that were developed in-house. Each supplied Polishmaster comes with 12 precision-milling cartridges and 10 pre-milling tools. The customer can cover an area of approx. 200 – 300 m2 with one tool.
Shipping of resharpening tools occurs via a worldwide distributor network. When tools arrive at the diamond shop, they are immediately checked for any damage. If the diamond tool cannot be resharpened, we replace it. Various work steps are required to offer the customer a high-precision tool. Tools are adjusted to 0.2 micron. If the customer demands an analysis, we can provide one based on an identical machine. Prior to shipping, each tool is checked via a microscope for damage or flaws.
These high-precision tools are shipped in a custom-made box. The Diamond shop handles the order process from start to finish. The entire team has been working passionately in the world of diamonds for many years. We value flexibility, quality, and on-time delivery.
The diamond tools are manufactured in Switzerland and distributed worldwide Daetwyler Graphics AG.
SAFETY COMES FIRST
Employee safety is a top priority in every company. Injuries must be avoided, and occupational safety, alongside the work environment, must be continuously improved. Daetwyler SwissTec‘s piece goods offer a variety of options for giving operators and technicians extra protection when mounting or using MDC doctor blades. The following solutions are available thanks to additional investments in our component manufacturing process:
• Piece goods with a straight cut and a corner radius of 4 mm (radius R4)
• Piece goods with a straight cut and a corner radius of 2 mm (radius R2)
• Piece goods with a straight cut (without radius)
With the „radius R4“ and „radius R2“ options, sharp edges at the ends of the pieces are eliminated, resulting in increased occupational safety when installing MDC doctor blades. The pre-made component, which is specific to the respective printing press, can be wound into rolls. The operator can remove the component from the roll as usual, or it is also possible to obtain the component packaged in cartons. When it comes to the production of piece goods, Daetwyler SwissTec’s flexibility will result in the perfect solution for any customer requirement. When working with MDC doctor blades, please continue to follow our general safety guidelines. For questions, please contact our local sales department or technical support. Feasibility is given for pieces from a length of 0.300m, widths of 25.0 - 80.0 mm and thicknesses of 0.150 and 0.200 mm. Price and availability upon request.
