Some may remember I posted about a month ago asking some basic questions about cutting mats. After some further research and looking around, I've decided to go ahead and get the Logan 760 cutter, which is $40 more expensive through Adorama than the 750 through Amazon (vs. the normal $100 price difference). The 760 will cut up to 60" mats as opposed to the 750 cutting up to 40" ... though I don't see an application of the larger ones at the moment, I don't see a reason to not spend the extra $40 to get the larger one in case I "need" to use it later on. At this point, though, I have a few more perhaps basic questions: (1) For cutting double mats, the interior mat is cut to the same outside dimensions as the top mat, right? (2) What do you use for backing? A second (third, fourth in the case of double or triple mat) piece of matboard seems somewhat expensive, but cardboard seems tacky. (3) What adhesives do you use for the photos? I've seen "archival artists' tape" recommended - is that the actual name of the product, or is there something more specific I should be looking for? Note that I don't want to invest in a dry-mounting system. (4) I'm assuming I will need to get a ruler as well. Can I just get like a metal yardstick from a hardware store, can I get by with something else, or do I need to go for something different? Or will the cutter have the ruler on it (I can't actually tell from the instruction manual nor photos on the site)? (5) After some reading on ply, I'm assuming I should generally go for 4-ply mats? (6) And there are SO MANY different types of matboard out there. Is there a concise listing somewhere (or can someone explain it?) that explains the basic types? Thanks for the help.
