Before making the impression, it is essential to clean the part thoroughly with the degreaser DN1 in order not to distort the roughness control.

In addition, its polymerization time is 6 to 8 minutes, which will allow you to work the surface of the impression in order to facilitate roughness control.

A method of controlling surface roughness of a flexographic printing element during thermal processing is provided.

The surface roughness (Rz) is a ten-point average roughness.

The roughness level of the micro contoured surface layer may be increased or decreased by controlling the process parameters.

The surface roughness Ra(b) and the surface roughness Ra(i) are arithmetical mean roughness values and are surface roughness parameters determined in accordance with a Germany standard "DIN-4768".

The back (100a) of the substrate of the InGaAs laser is processed into an optically irregularly reflecting face having a continuous irregularity the surface roughness (Rq: root mean square roughness) of which is 100 nm.

Said receiving device (2) comprises a measurement standard (24) having a measurement surface (25) near the roughness sensor (4).

The roughness, the degree of gloss, and the visual impression provide a basis for inspection checks.
