Lucille, sorry, your file was ~80KB, however you saved it as a .psd instead of a jpg. As a jpg it is only 16KB on medium compression which means you could have attached a jpg which was about 5 times larger than the one you attached. In any case, I can see those lines at all sizes included 100%.
My comments and questions regarding texture and scanner still stand.
Regards, Murray

The original artwork did not have texture. The lines are the direct result of the scanning process (24bit scanner).

The output is the result of a flatbed scanner with transparency adapter. The input was a 4x5 positive Fuji 64T transparency taken with a large format Cambo studio camera fitted with color copy lens.

I am asking is this type of striation inherent in all scans? Is it peculiar to my (perhaps obsolete technology) scanner? Scan quality is a huge issue here. If I purchase a 48bit scanner with transparency adapter can I hope that these lines will not be apparent?

Please find attached a larger jpeg sample. Thanks in advance for any help.

Lucile, thanks for the larger sample. I have had many scanners and have never seen these straitions or such intense color noise in any of them. If this pattern is not on your transparency then it may well be an anomaly of that specifc scanner. Have you tried any other negatives or transparencies to see if you can repeat the pattern?
Regards, Murray

Everything (all positives, negs & transparencies) scanned has the lines. It sounds as though a better scanner will do a better job. Thank you all.
