據科技博客網站Gizmodo報道，一臺名叫“懺悔錄”打印機的設備不用石墨，而是用LED紫外燈在光敏紙張上打印人們做出的懺悔，隨著時間的流逝，紙上的內容也會消失。

除非你真的想實現一個無紙化辦公的環境，利亞特·西格爾的 “懺悔錄”打印機不適合打印工作中的TPT報告。這款打印機不采用墨水或石墨，利用16個紫外線LED燈在一張布滿感光顏料的紙張上“打印”信息，當打印的燈頭經過后不久，紙張上就顯示出藍色的打印痕跡。

但打印出來的內容只能在紙上停留一會呢?西格爾的設計意圖是將在各種社交網站上披露的私密且匿名的懺悔錄打印出來。他認為，如果將這些內容公布，就等同于本人承認了自己的錯誤，可以釋懷了。隨著字跡的逐漸淡化，就象征著過去所犯下的錯誤逐漸被原諒和遺忘。法院應該不會采用這種方式來接受人們的懺悔吧……

This LED Printer Creates Fleeting Messages on Photosensitive Paper

Liat Segal's Confession Machine printer isn't designed for running copies of TPT reports at work, unless you're really making an effort to realize a truly paperless office. Because instead of ink or toner, Segal's creation uses an array of 16 ultraviolet LEDs to 'print' messages on a static surface covered with a photosensitive paint that turns bright blue as the printhead passes over—but only momentarily.

But why the temporary fleeting results? Segal's creation is designed to print intimate but anonymous confessions that have been revealed on various social networks. By making them public, it's as if the person is admitting to their mistake—so it's no longer hanging over the heads. And as the messages fade, it's as if the mistake is being actively forgiven and forgotten. If only the courts agreed to adopt this technology.
