8x10 contact print and scan

[basiltahan]

I have had no luck scanning 8x10 sheets without getting newton rings. Would it be feasible to make a contact print on glossy paper and scan that for making a large digital print? How much resolution would be lost?

When you say 8x10 sheets, do you mean film? What scanner are you using?

[basiltahan]

Yes, sheets.

Epson V700.

Not all that happy with the 4x5 scans either, even in the film holder above the glass (no newton rings)

Try wet mounting.

Sounds messy. And risky. And toxic?

I really want to build a fixed lens 16x20 enlarger.

Wet mounting is the best way to go, but lacking that, try scanning it emulsion side down and then flip the image in your photo editing program. Some films seem to be more prone to newton rings too - what type of film are you scanning?

Both Ilford 100 Professional and TMAX 100.

I'll try emulsion side down, but I think that is what I have been doing.

I've just scanned some Ilford FP4+ 8x10 negs emulsion side up (the way it is supposed to be scanned) and did not see any newton rings. I have the Epson V750.

Hello, I use Epson perfection 4880 scanner and Epson V750 in both sheets can be scanned 8x10 (negatives or slides) ... and I bought a special anti newton frosted glass, no problems with that and I can also scan other smaller formats 8x10. Panoramic even

Where does the anti newton glass sit?

Go to your local glass store and buy two pieces of anti-glare picture frame glass. Get it cut somewhere between 8x10 and the size of the glass on your enlarger. Place one piece of glass on the scanner, frosted side up, add the negative, and put the second piece, frosted side down on top of the negative. In other words, the negative sits between the rougher surfaces of the glass and eliminates Newton's rings. There was a long discussion of this technique with the Epson 48XX scanner on this forum - probably 2007 or 2008.

This method is cheap and easily accomplished. The only trouble is that you have more surfaces to check for dust. On the older Epson, and reputedly on the 700, the extra glass puts the negative in better focus.
