Screen Platerite 8100 Banding


We have this strange banding on plates, which is more visible in solids. This effect is in entire plate, despite plate brand. Any Help on this?

Hey Kandy,

You noted your platesetter but not the plate material or what screen ruling you are using.

Looks a bit like focus or vacuum problem but would be easier with more inof.

Hi Kandy,

Based on the image, the following things come to mind:
1) Something is physically blocking the laser that exposes the plate as the streaks are consistent, so maybe check the optical path for dust.
2) I have seen banding like this when a driver for a laser had a bad buffer
Hi theShaft, thanks for the reply. We are using Kodak plates. We tried using a chinese plate as well but same problem comes up. We use Kodak Developer well as Technova Developer.

I think I have changed the focus values some time back.

DR} I have to check on buffer, screen technician is out of the country for 3 weeks so have to wait for dust issue.

Can I know how focus values work?
