Hi,
This is regarding the Imaging process in digital presses.
I am bit confused about the resolution part, I know that imaging can be done by either LED or LASER, so when we say 600X600 or 1200 X 1200 its done by LED and bit depth is adjusted to achieve req. gray levels.
In case of LASER, resolution is like 2400 dpi and bit depth cannot be varied.
What I want to know is that, whether quality from LASER imaging system will always be better than LED ?
What will be the difference in Dot quality, speed, and cost of the equipment, also will there be a difference in maintenance part ?
and one more.. In digital, Is the screening pattern, dot shape, size and screen angles similar to that of offset ?
Regards,
Umesh
