RODOLFO COMERIO Proposes Embossing in Register

Further to recent research by RODOLFO COMERIO there has been an increased interest from the interior design world for the production of wood-grain laminated materials and floor-coverings composed by a substrate encapsulating a certain number of PVC layers possibly reinforced with fibre glass, reproducing exactly the appearance and feel of solid wood flooring 

The progress in the printing techniques, allows to obtain a very high quality, able to imitate very well any kind of natural material. However, this is not sufficient to give an acceptable appearance to the product.

To overcome this problem, the laminated material is at the moment submitted to an embossing process. But, such technique does not provide satisfactory results as the engraved roll creates an embossing which is not coordinated with the printing pattern.

In order to cope with this disadvantage embossing in register is carried out discontinuously thus, involving a slow process, and the press used for embossing is expensive and cumbersome.

Since the laminated material considered hereby is, by its nature, an economical product, the process needs to be simplified. For this purpose, there is the necessity to carry out an embossing in continuous.

Specific systems have been invented and patented by RODOLFO COMERIO, which have the aim to place at disposal an effective, quick and economical technology for the embossing in register.


The process includes register control operations of the engraved roll, to maintain synchronism between embossing and pattern of the printed film, by means of proper patented register control shifting of the engraved roll (Embossing-in-Register EIR).

The term register control shifting refers to the necessary corrections of the engraved roll rotation so that embossing is properly synchronized with pattern of the printed film.

PATENT FOR SURFACE EMBOSSING OF AN EXTENSIBLE PRINTED FILM An extensible film is, in fact, subject to significant and unforecastable length variations.

The consequence of the elongation of the extensible film is that pattern itself is deformed, thus causing the alteration of the distance between registration marks printed on the film.

In other words, when using an extensible film, the synchronism between embossing and printing is made even more complicated due to the deformation of the printed film.

RODOLFO COMERIO has studied the solution to match the print pattern to the engraved roll circumference, thanks to a RODOLFO COMERIO patented Embossing – in – Register (EIR) effect.
