摘要： A label that changes appearance with time is disclosed. The label comprises a first layer that has different permeabilities to a gas in different lateral areas of the label and which comprises a substance that changes colour when in contact with the gas. The substance is arranged within the label such that the gas permeates across the thickness of the layer at different rates in different lateral areas so as to cause the substance to change colour at different rates in said different areas. Another label that changes appearance with time is disclosed that allows ink to permeate to its surface at different rates in different lateral areas.

摘要： A method and system of modifying a substrate (8) using a plasma are described comprising providing a first electrode (4) and a second electrode (6); arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis (80) of linear displacement during said movement; and wherein said second electrode is arranged relative to said axis of linear displacement such that said linear movement causes a first section of the portion of substrate to have a greater residence time between the electrodes during said linear displacement than a second section of said portion of the substrate. A method and system of modifying a substrate (8) using a plasma is also described comprising providing a first electrode (4) and a second electrode (6); arranging the substrate such that a portion of the substrate is between the electrodes; supplying a voltage to at least one of the electrodes so as to create a plasma discharge between the electrodes which contacts at least said portion of the substrate, moving either the substrate and/or said second electrode such that said substrate and said second electrode are being linearly displaced relative to each other along an axis (80) of linear displacement during said movement; and further comprising the step of rotating either the substrate or said second electrode about an axis of rotation during said relative linear displacement along said axis (80), so that a first section of the portion of substrate has a greater residence time between the electrodes than a second section of said portion of substrate.
