Process of preparing an organic electronic device, comprising the steps of a) depositing a formulation comprising one or more organic semiconducting compounds, and one or more organic solvents, and at least one inert binder, characterized in that said formulation comprises a viscosity at 25°C of less than 15 mPas and the boiling point of the solvent is at most 400°C, characterized in that said inert binder is a polymer comprising repeating units derived from styrene monomers and/or olefins and characterized in that said inert binder is a polymer having a weight average molecular weight of at least 200,000 g/mol, onto a substrate to form a film or layer, b) removing the solvent(s), characterized in that the formulation is applied by gravure printing or flexographic printing, characterized in that said organic solvent or solvent blend is a mixture of hydrocarbon aromatic compounds, characterized in that said organic solvent comprises a boiling point of at least 130°C, characterized in that the formulation comprises 0.1 to 5 % by weight organic semiconducting compounds, and characterized in that the organic semiconducting compound is a compound of the following formula wherein one of Y 1 and Y 2 denotes -CH= or =CH- and the other denotes -X-, one of Y 3 and Y 4 denotes -CH= or =CH- and the other denotes -X-, X is -O-, -S-, -Se- or -NR"'-, R' is H, F, Cl, Br, I, CN, straight-chain or branched alkyl or alkoxy that have 1 to 20 C-atoms and are optionally fluorinated or perfluorinated, optionally fluorinated or perfluorinated aryl having 6 to 30 C-atoms, or CO 2 R"", with R"" being H, optionally fluorinated alkyl having 1 to 20 C-atoms or optionally fluorinated aryl having 2 to 30 C-atoms, R" is, in case of multiple occurrence independently of one another, cyclic, straight-chain or branched alkyl or alkoxy that have 1 to 20, preferably 1 to 8 C-atoms, or aryl having 2-30 C-atoms, all of which are optionally fluorinated or perfluorinated, R'" is H or cyclic, straight-chain or branched alkyl with 1 to 10 C-atoms, m is 0 or 1, o is 0 or 1. a) depositing a formulation comprising one or more organic semiconducting compounds, and one or more organic solvents, and at least one inert binder, characterized in that said formulation comprises a viscosity at 25°C of less than 15 mPas and the boiling point of the solvent is at most 400°C, characterized in that said inert binder is a polymer comprising repeating units derived from styrene monomers and/or olefins and characterized in that said inert binder is a polymer having a weight average molecular weight of at least 200,000 g/mol, onto a substrate to form a film or layer, b) removing the solvent(s), one of Y 1 and Y 2 denotes -CH= or =CH- and the other denotes -X-, one of Y 3 and Y 4 denotes -CH= or =CH- and the other denotes -X-, X is -O-, -S-, -Se- or -NR"'-, R' is H, F, Cl, Br, I, CN, straight-chain or branched alkyl or alkoxy that have 1 to 20 C-atoms and are optionally fluorinated or perfluorinated, optionally fluorinated or perfluorinated aryl having 6 to 30 C-atoms, or CO 2 R"", with R"" being H, optionally fluorinated alkyl having 1 to 20 C-atoms or optionally fluorinated aryl having 2 to 30 C-atoms, R" is, in case of multiple occurrence independently of one another, cyclic, straight-chain or branched alkyl or alkoxy that have 1 to 20, preferably 1 to 8 C-atoms, or aryl having 2-30 C-atoms, all of which are optionally fluorinated or perfluorinated, R'" is H or cyclic, straight-chain or branched alkyl with 1 to 10 C-atoms, m is 0 or 1, o is 0 or 1.
