In-mould-decoration method using an apparatus that has an injection tool including a first tool portion having a first mould recess and a second tool portion, wherein the first or the second tool portion (11, 12) has an injection passage, wherein a decorative film, preferably formed as an endless decorative film, is inserted in the apparatus, and wherein the following steps are cyclically performed: a) providing a portion of the decorative film on the first tool portion or on the second tool portion in such a way that, when the injection tool is closed, the decorative film lies on an end face of the raised edge region which delimits the first mould recess and which extends around the mould recess; b) closing the injection tool to such an extent that in the region of the end face of the raised edge region between the first tool portion and the second tool portion a gap is formed between the end face of the raised edge region of the first tool portion and the corresponding end face of the second tool portion at least over a subregion, and the gap is sealed off by the interposed compressed decorative film which is pinched in the region of the gap; c) injecting a plastic melt through the injection passage into the injection tool, wherein the plastic melt is injected behind the decorative film in the region surrounded by the raised edge region without plastic melt passing through the sealed gap so that a decorated plastic part is produced; d) opening the injection tool by moving the first and the second tool portions (11, 12) relatively away from each other and removing the decorated plastic part from the injection tool; e) removing the residual portion of the decorative film and providing a further portion of the decorative film, characterised in that, when the injection tool is closed, the spacing (s) of the end face of the raised edge region and the corresponding end face of the second tool portion is less than 50%, preferably 20% to 10% of the thickness of the provided decorative film, and the decorative film is formed as a lamination film that is of a thickness in the range of between 20μm to 500μm. a) providing a portion of the decorative film on the first tool portion or on the second tool portion in such a way that, when the injection tool is closed, the decorative film lies on an end face of the raised edge region which delimits the first mould recess and which extends around the mould recess; b) closing the injection tool to such an extent that in the region of the end face of the raised edge region between the first tool portion and the second tool portion a gap is formed between the end face of the raised edge region of the first tool portion and the corresponding end face of the second tool portion at least over a subregion, and the gap is sealed off by the interposed compressed decorative film which is pinched in the region of the gap; c) injecting a plastic melt through the injection passage into the injection tool, wherein the plastic melt is injected behind the decorative film in the region surrounded by the raised edge region without plastic melt passing through the sealed gap so that a decorated plastic part is produced; d) opening the injection tool by moving the first and the second tool portions (11, 12) relatively away from each other and removing the decorated plastic part from the injection tool; e) removing the residual portion of the decorative film and providing a further portion of the decorative film, characterised in that, when the injection tool is closed, the spacing (s) of the end face of the raised edge region and the corresponding end face of the second tool portion is less than 50%, preferably 20% to 10% of the thickness of the provided decorative film, and the decorative film is formed as a lamination film that is of a thickness in the range of between 20μm to 500μm.
