## Abstract

A method for manufacturing a printed product comprises provision (210) of a matrix comprising a matrix surface having a plurality of recesses. A first curable compound is applied (212) to the matrix surface to fill the recesses with the compound. The matrix surface and the filled recesses are covered (220) by a pickup layer of a second curable compound. The matrix is brought (230) in contact with the substrate surface and the first curable compound and the second curable compound are cured (232). The matrix surface is separated (234) from the substrate surface, leaving the pickup layer and the first curable compound on the substrate surface. The pickup layer and the first curable compound are thus transferred (240) together from the matrix surface onto a substrate surface of a substrate sheet. The first curable compound forms printed product micro features at the pickup layer covering the substrate surface.

## Claims

### Claim at position 1

1-12. (canceled)

### Claim 13

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.

### Claim 14 (depends on 13)

The method according to claim 13, comprising the further step of pre-curing said first curable compound in said recesses before said step of covering said matrix surface and said recesses filled with said first curable compound by a pickup layer.

### Claim 15 (depends on 13)

The method according to claim 13, comprising the further step of removing excessive said first curable compound from said matrix surface outside said recesses before said step of covering said matrix surface and said recesses filled with said first curable compound by a pickup layer.

### Claim 16 (depends on 14)

The method according to claim 14, comprising the further step of removing excessive said first curable compound from said matrix surface outside said recesses before said step of covering said matrix surface and said recesses filled with said first curable compound by a pickup layer.

### Claim 17 (depends on 16)

The method according to claim 16, wherein said step of pre-curing, at least to a part, is performed before said step of removing excessive said first curable compound.

### Claim 18 (depends on 13)

The method according to claim 13, wherein said first curable compound is the same as said second curable compound.

### Claim 19 (depends on 13)

The method according to claim 13, wherein said first curable compound is different from said second curable compound.

### Claim 20 (depends on 13)

The method according to claim 13, comprising the further step of providing said substrate with a wetting surface layer before said step of bringing said matrix in contact with said substrate surface.

### Claim 21

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.

### Claim 22 (depends on 21)

The arrangement according to claim 21, further comprising a pre-curing means, arranged for pre-curing said first curable compound in said recesses, said pre-curing means being arranged, in said rotational direction, before said second applicator.

### Claim 23 (depends on 21)

The arrangement according to claim 21, further comprising removal means arranged for removal of excessive said first curable compound from said circumferential surface of said matrix roll outside said recesses, said removal means being arranged, in said rotational direction, before said second applicator.

### Claim 24 (depends on 22)

The arrangement according to claim 22, further comprising removal means arranged for removal of excessive said first curable compound from said circumferential surface of said matrix roll outside said recesses, said removal means being arranged, in said rotational direction, before said second applicator.

### Claim 25 (depends on 24)

The arrangement according to claim 24, wherein said pre-curing means is arranged to perform said pre-curing at least to a part before said removing of excessive said first curable compound.

### Claim 26 (depends on 21)

The arrangement according to claim 21, further comprising a wetting layer applicator arranged for providing a wetting layer on said substrate.

### Claim 27 (depends on 14)

The method according to claim 14, wherein said first curable compound is the same as said second curable compound.

### Claim 28 (depends on 15)

The method according to claim 15, wherein said first curable compound is the same as said second curable compound.

### Claim 29 (depends on 16)

The method according to claim 16, wherein said first curable compound is the same as said second curable compound.

### Claim 30 (depends on 17)

The method according to claim 17, wherein said first curable compound is the same as said second curable compound.

### Claim 31 (depends on 14)
