Abstract A printed reading material of foreign language with hidden translated meaning features that its translation is printed in microprint mode with a special ink which has no colour or the colour similar to that of paper, so it can not been seen directly by eyes. Under the physical or chemical action condition, the colour of said ink changes, so the translation can be seen by means of a magnifier with a device to provide needed physical or chemical action.
