Claim:
1. A method for producing and monitoring oral dissolvable films comprising a base whereto a solution comprising at least one active compound is applied, said method comprising the steps of (a) dosing and mixing a base formulation, (b) coating the base formulation onto a support to form a support-coated base formulation web, (c) optionally drying the support-coated base formulation web, (d) printing a dye solution comprising the at least one active compound onto an upper side of the support-coated base formulation web by flexographic printing, thereby obtaining a printed active compound solution, (e) drying the support-coated base formulation web along with the printed active compound solution, (f) passing radiation from a radiation source from the upper and/or a lower side through the support-coated base formulation web along with the printed active compound solution, (g) measuring transmitted radiation using at least one receiving unit on a side of the support-coated base formulation web which is opposite to the radiation source, along with the printed active compound solution, wherein the transmission of the transmitted radiation correlates with the concentration of the at least one active compound, thereby measuring the concentration of the at least one active compound.
