What paper do you use for scanning artwork on AOI?

Hello,

I am new to this forum but I have a question. We use an Orbotech Discovery Ultra to inspect our photo-tools. We currently use this lint free paper as a contrast material underneath the phototool since the vacuum bed on the AOI is black and our trace work on the photo-tool is black. This material is porous so the vacuum will still work on the photo-tool as well as the paper. We are finding this is not the best solution as the contrast could be a little better if the paper were a little whiter, and there is still FOD left behind from the paper a little. I have been told at one point Orbotech made paper for this purpose but the do not anymore.

Any suggestions?
