Regarding the DPI for the JP scans, I received the following feedback from Pam at Pinbits today.
I don’t think it matters. ( we are not using the images, just the shape and position of holes/slots- lamps etc.)
What is important is to scan a tape measure or thin ruler with the scan so I can calibrate the image size.
So according to Pam the DPI is really irrelevant and also be sure to include a thin ruler with the scan so that Pam is able to properly calibrate the image size. Please keep the JP plastic scan images coming and we can get some JP plastic protector sets created.
