Umax Astra 1200S Moire pattern getting worse
If anyone can offer advice on this I would really appreciate it.
I've had this UMAX Astra 100S for 5 years and primarily use it to scan comic book covers for storage. I use the VistaScan software and have descreening on. I have used the same settings for the past 5 years and have never had a moire pattern problem on the scans. However, in the last 2 months, I am noticing a worsening moire pattern with about 50% of my scans. I am wonderinging if the lamp on the sacnner is deteriorating and causing this as I see no other reason for the moire pattern to start appearing. Does anybody have experience or suggestions on what may be happening? |

I do not have instruction for a Umax, but you can get the idea from my cleaning the Canon 8400F. http://www.carlmcmillan.com/CanonScanner/Canon.htm Any smoke from cigarettes or a wood fire will add a haze to the scans, smoke goes everywhere and gets on everything. You could try the Manual method of descreening and see if the scanner is going bad. Or if the software needs to be re-installed. http://www.scantips.com/basics6c.html -- CSM1 http://www.carlmcmillan.com -- |

I thought that might be part of it and I took the scanner apart and cleaned the glass and blew out any debris. I did not clean the lens or mirror so that may be the problem. I'll try that next. I have tried manual descreening. It works but the resulting image is not as clear as it normally is with the descreening that takes place during the scan. I also purchased Silverfast AI figuring I'd try that software out. Hal |
