[QUOTE="JGobeil, post: 1236552, member: 24649"] Here is a tentative for a new version of the target. It makes it easier to evaluate the resolution, specially when we will be working at high magnification. and only one post will be required instead of 3. However, it does not change anything - the lines and the spaces are just bigger. Printing the target on an inkjet at 300ppi, I easily see all lines and spaces at the maximum 20 resolution. Taking a full screen picture at 896mm, I get a very net 20 resolution. Right click on the image and copy the file - you should get a 10"x7.5" 300ppi image.
