Liquids for the pre-treatment of liquid absorbing substrates, in particular textiles or garments, in printing processes are disclosed, said liquids being based on water and/or a low molecular alcohol and including small amounts of an organic acid and/or other reagents to increase dye fixation as well as at least one corrosion inhibiting agent selected from a group containing quaternary ammonium salts, derivates thereof and their corresponding organically substituted amines, hydroxy substituted acetylenic components and derivates thereof, carboxylic, dicarboxylic and polycarboxylic acids, long-chain carboxylic, dicarboxylic and polycarboxylic acids and separated fractions and derivates thereof, sulfur containing heterocyclic compounds and derivates thereof, nitrogen containing heterocyclic compounds and derivates thereof, nitrite and nitrate salts of metal ions, organic nitrites and nitrates, organic nitrogen compounds and reductive nitrogen containing compounds. Preferably the concentration of the corrosion inhibiting agent is between 0.01 wt. % and 10 wt. % and the surface tension of the liquid between 15 mN/m and 70 mN/m.
