Help With Defect Samples

Posted by Edward Cohen on October 21, 2011
 

I am in the process of collecting web coated Defect Samples to be used to prepare a “Defect Catalogue”.  If any one has extra defect samples that they can spare, I would appreciate your sending them to me. I would like to obtain sheets with the defect name and if possible the defect cause.  Also, if you have micrographs that you would be willing to share with the same information, I would appreciate these.

Thank you for your help.
