Method for manufacturing of printed product micro features and arrangement for continuous production of such a product

A method for manufacturing a printed product, comprising the steps of:

• a) providing a matrix comprising a matrix surface having a plurality of recesses;
• and
• b) applying a first curable compound to said matrix surface and said recesses so as to fill said recesses with said first curable compound;
• c) covering said matrix surface and said recesses filled with said first curable compound by a pickup layer of a second curable compound;
• d) bringing said matrix in contact with a substrate surface of a substrate sheet;
• e) curing, at least partly, said first curable compound and said second curable compound;
• and
• f) separating said matrix surface from said substrate surface, leaving said pickup layer and said first curable compound on said substrate surface;
• wherein said pickup layer and said first curable compound filling said recesses are transferred together from said matrix surface onto said substrate surface;
• and
• wherein said first curable compound forms printed product micro features at said pickup layer covering said substrate surface.

An arrangement for continuous production of a printed product, comprising:

• a matrix roll having a circumferential surface with recesses;
• a first applicator arranged for application of a first curable compound onto said matrix roll so as to fill said recesses with said first curable compound;
• drive unit arranged for rotating said matrix roll in a rotational direction;
• substrate guides, arranged for bringing a substrate sheet in contact with said matrix roll in a contact section;
• curing means;
• a second applicator, separate from said first applicator, arranged for covering said circumferential surface and said recesses filled with said first curable compound by a pickup layer of a second curable compound;
• wherein said contact section is situated, in said rotational direction, after said second applicator;
• wherein said pickup layer and said first curable compound are transferred together from said circumferential surface and left on a substrate surface of said substrate sheet;
• wherein said first curable compound forms printed product micro features at said pickup layer covering said substrate surface;
• and
• said curing means being arranged for curing said first curable compound and said second curable compound;
• said curing means being arranged to perform said curing at least to a part in said contact section.
