The technical problems<br />
Imaging itself is no problem but a well known technology.<br />
The main problem is the function layer on cylinder:<br />
1. It has to be very uniform to exclude image errors<br />
2. It has to be durable in the offset printing process for<br />
higher run length<br />
3. It has to be totally erasable (within a molecular scale!)<br />
for many job changes to avoid ghost image from the<br />
job which has run before.<br />
