An inkset and a process for direct inkjet printing color images on dyed synthetic fabrics is provided herewith, based on forming an image on the fabric in the form of a well-adhered crosslinked film, using an acid-immobilized ink composition, while avoiding dye migration from the fabric to the image in the process of curing the film, using a low-temperature curing crosslinking agent and curing the image at a temperature lower than 120±5° C.

A method pretreats a printing material used for ink printing to influence the spreading of ink print dots on the printing material. The spreading behavior is influenced in such a way that the ink print dots spread in an anisotropic way. The anisotropic spreading advantageously allows undesired quality losses in the print that are caused by a failed ink nozzle to be reduced or avoided. The influencing of the spreading behavior may be achieved by an anisotropic application of a liquid, in particular a primer or varnish, to the printing material, or by an anisotropic embossment or print on the printing material or by an anisotropic treatment of the printing material with charged particles, in particular by a plasma or a corona, or with electromagnetic radiation, in particular laser radiation.
