Abstract

This translucent label can be read when it is either backside illuminated or observed in daylight. These results are obtained with a translucent substrate on which are placed previously colored opaque characters. The process for making this label includes: 1. Preparing sheet 1 of transparent plastic material like polyethylene terephthalate 0.2 mm thick, 2. Coating sheet 1 with layer 3 of copper 0.02 mm thick which adheres by a layer of glue 2, 3. Silk-screening of the pattern 4 of characters to be etched with a suitable colored ink, and 4. Etching the uncovered portion of copper with an etchant which does not react with the glue coating.

Translucent Labels

This translucent label can be read when it is either backside illuminated or observed in daylight. These results are obtained with a translucent substrate on which are placed previously colored opaque characters.

The process for making this label includes:
1. Preparing sheet 1 of transparent plastic material like

polyethylene terephthalate 0.2 mm thick,
2. Coating sheet 1 with layer 3 of copper 0.02 mm thick which

adheres by a layer of glue 2,
3. Silk-screening of the pattern 4 of characters to be etched

with a suitable colored ink, and
4. Etching the uncovered portion of copper with an etchant which

does not react with the glue coating.

The resulting label includes a substrate which is translucent because of the glue coating and partially opaque because of the inked copper pattern. An alternative label can be obtained by replacing the silk-screened colored ink by an electrolessly deposited tin configuration.
