Advice on artwork scans

[msamiullah]

I have recently acquired an Epson Expression 11000XL scanner and plan to do scans of all the artwork that I have. I am planning to scan the artwork in 2400dpi in 48bit colors with outputs to both lossless TIFF and lossy JPG files. As the process is quite time consuming I thought I will check before hand if these scan settings make sense to you or some changes are required here.
Let me know.

2400dpi is super overkill. 1200dpi is plenty enough.

Or even 600dpi.

Personally, I scan everything in 600dpi. I scan artwork to have it printed again, and once you print something that has been scanned, there is no discernible difference between 600dpi and 1200dpi.

I scanned a NOS 1P Lindbergh sticker just now. It's 50mm by 40mm. One scan is 600dpi, the other 1200dpi. Do you see a difference?

1200dpi just takes longer to scan and results in a file size that is four times as large.

thanks nem, thats exactly the reason I am scanning if someone wants to reproduce these in future. I think I will go with 1200dpi just in case. For neogeo marquees would it make a difference (for reproduction) scanning these just like normal paper as opposed to treating it like a positive/slide film (I currently do not have the transparency unit for the scanner but plan to get it in future).
