Heidelberg makes upgrades in in-mould label production



Heidelberg announced several new advancements in its portfolio for in-mould label production. The company expects the global label printing market to continue growing at an annual rate of around 4%. Growth is even expected to be above average in the in-mould label segment, which has not been affected by the COVID-19 pandemic.


Cutting-edge, increasingly efficient manufacturing processes are a further growth factor on the in-mould label market. With its state-of-the-art technology, Heidelberg is playing a key role in improving the efficiency of in-mould label production and stepping up its investment in the development of new technologies for IML production.


Maximum performance with the thinnest of materials


One of the major challenges for label printers is to reliably process very thin and light films at ever higher speeds. The latest advance from Heidelberg is a new IML Performance Package for the 2020 generation Speedmaster XL 106 with fully automatic presetting of all key print job parameters.


Special modifications to the feeder and delivery, modified sheet transfer, and anti-static devices make it possible to reliably process delicate plastic films just 50 microns thick at speeds of up to 14,000 sheets per hour. The high-performance model for conventional offset printing is equipped with three Y units (drying units) and a delivery with only one extension module. Even with extremely thin substrates, customers benefit from reliable sheet guidance and smooth travel through the press. The dryer modules are perfectly coordinated with the sheet travel and achieve outstanding drying results at maximum speeds.


Distances for paper travel in the delivery remain short and, even at high speeds, sheets are completely stable when deposited on the delivery pile. The configuration with three Y units and highly efficient round-nozzle technology increases the drying capacity by 25 percent and also saves on energy costs, because the distance between the dryer modules and the substrate can be kept to a minimum.


Heidelberg is unveiling the system as part of “IT’S SHOWTIME” – the company’s digital customer event.


Prinect integrates new CutStar generation 4 into Push to Stop concept


The redesigned CutStar generation 4 is the basic prerequisite for processing thin substrates at consistently higher speeds. The sheeter is fully integrated into the Prinect workflow and the Intellistart system on the press for production based on the Push to Stop principle.


The format and air values are adjusted fully automatically based on the job data. These settings can be saved and loaded with the print job for repeat orders.


A further innovation is the special corona surface treatment integrated into the CutStar, which improves the wettability of plastic materials and makes them easier to print on than untreated materials. The enhanced ink adherence ensures long-lasting, consistently high quality.


Speedmaster XL 106-D with just one die-cutting unit makes it easier for customers to move into IML production


Another part of the IML Performance Package is the Speedmaster XL 106-D rotary die cutter, which now has only one die-cutting unit. Lower investment costs compared with the previous version means it is easier for print shops to move into the growing in-mould label production segment. The new die cutter requires less space and has a lower power consumption than the Speedmaster XL 106-DD. It is ideal for die-cutting large and nested label shapes.


Thanks to its rotary die-cutting principle, the Speedmaster XL 106-D operates at two or three times the speed of flat-bed die cutters. The high precision resulting from the even cylinder surface and evenly cutting die eliminates the makeready required due to differences in level when using the flat-bed process. This time-consuming step is not necessary and minimizes the setup time. The printing pressure can be adjusted in increments of just one micron on the Speedmaster XL 106-D.


Corrections are possible both parallel and diagonal to the cylinder axis. This fine adjustment makes Heidelberg rotary die cutters perfect for in-mould label production on material just 50 microns thick.


The Speedmaster XL 106-D complements the existing portfolio of rotary die cutters, from the Speedmaster XL 106-DD and the option magnetic cylinder with extraction system for cutting holes.
