AI Article Synopsis
- A 1W laser diode can effectively cut conventional paper when used with a specially formulated ink that absorbs laser light and penetrates into the paper.
- An "invisible ink" that is transparent to visible light but absorbs infrared light has been tested successfully for this application.
- The cutting speed can exceed 3 cm.s-1.W-1, allowing for precision cuts, and at higher speeds, the paper can be marked for easy ripping or folding, which could be integrated into future inkjet printers for enhanced document creation.
Article Abstract
We show that conventional paper can be cut using a 1W laser diode, provided the cutting lines are first traced using a proper ink. The ink should absorb the laser light, and penetrate deep into the paper. An "invisible ink" that is transparent in the visible range and absorbing in the infrared has been successfully tested. The paper is tidily cut. The laser power required to cut the paper is proportional to the displacement speed of the paper. Cutting speeds exceeding 3 cm.s-1.W-1 have been demonstrated. At higher speeds, the paper is not cut through, but easy-tearable lines and easy-folding lines are obtained. The whole inking and laser cutting process may be integrated into next generations of personal inkjet printers and expand document creation abilities.
