Questions regarding BlueScan48 and Silverfast

[iblink]

Hello

I have a new Bluescan48 and the latest Silverfast software and I have a couple of questions:

- When I scan 8" x 10" transparencies I find a pattern of vertical lines in the dark regions of the image, particularly in the blue channel. I know this is an aspect of flatbed scanning but is there anything I can do to minimize them in your software?

- I have made profiles for transparency and reflective materials, following the manual instructions. Both profiles show up in the CMS tab in the transparency pop up menu but a greyed out "none" appears in the reflective pop up menu. How do I set the reflective profile?

- Near the center of the image there are often, but not always, two very fine verticle white lines that go from the top to the bottom of the image. What are they, and how do I avoid them?

- Finally, this is not a Silverfast issue, but do you have any suggestions for removing the occasional Newton ring?

Thank you, - M

Dear iblink

thanks for your interest in LaserSoft Imaging's scanning software solutions.

It seems to me that the best approach to avoid Newton rings is to remove the source of the phenomenon. There are glassless slide holders available which you want to give a try.

Concerning your lines and CMS problems, please don't hesitate to contact LaserSoft Imaging support staff: http://www.silverfast.com/problemreport/en.html

I would appreciate if you could paste a fresh copy of the SF_Logfile in the problem report.

On a Mac OS X PC you will find the SF_Logfile in /Users/(your username)/Library/Preferences/LaserSoft Imaging.

On a Windows 2000 or XP system the SF_Logfile is placed within /Documents and Settings/(your username)/Application Data/LaserSoft Imaging.
If you haven't yet changed the standard setting of the Windows Explorer you won't see any folder "Application Data". You then want to open the folder options dialogue (from "Extras" the menu) and go to the "View" tab. There you can enable the Explorer to show you hidden and system files and folders as well as displaying the contents of system folders.

Simply open it with your text editor (double clicking the SF_Logfile) and select all the text (Win: CTRL+A; Mac: CMD+A). Then copy the selection to the clipboard (CTRL+C / CMD+C).
Go back to the problem report and click inside the text field. Move the text cursor to the end of your problem description and insert the SF_Logfile from the clipboard (CTRL+V / CMD+V).

You shall receive an automatic confirmation email for such a problem report. Please reply with attached sample scan(s) and/or screenshot(s) to illustrate your trouble.

Thank you very much in advance.

Kind regards
