There is soooo much that I could reply to this on.
Your reply was in a language that I understand. I have dealt with all of these file types for years in my profession. I was a Graphic Artist for 30 years. I specialized in Photoshop and got my first Photoshop in 1989 as well as my first Mac. (Really pissed my Dad off as he was one of IBM's original programmers)
As for patterns I really don't care what format I get it in. I always convert them to layered TIF files. That has the best image quality and has the greatest editing capabilities. The down size to that is size, Layered TIF files are pretty large. 8.5x11@300dpi = around 25mg's in Black & White. I then store my images on my computer which syncs to Cloud Storage. That way I can access my patterns from my Apple Watch, My Iphone, My Ipad, My MacBook or one of my 2 Imacs pretty much wherever I may be. If I don't want to forget to print a pattern I just send it over the internet to my printer at home and have it waiting for me.
With the layered TIF I sometimes alter them and create a VECTOR path. That way I can make super minute changes if I want.
If I post a pattern that I made I generally just save it as a JPG file. I compress them down so they take up less server space. They also can be opened by more programs than any other file type that I work with. Compatible across all different platforms.
Now as for pattern color and outline. When I print my pattern I put the black at 40% with no outline, I have by trial and error tried many different densities and have found that this works best for me. I don't really like outlines because they hide my blade if they are black.
My printer has a max size of 8.5x11. When I need a pattern larger then that say 11x14, I take my original pattern and drag 2 different pieces to a pattern printing template that I have pre made. Since I have a decent eyes and it is not that critical I do not use crop (printers) marks. I just print, cut with scissors and tape.
I have made a couple of patterns that I wanted to be exact. I printed sections of the pattern and utilized crop marks. Then lined up the different pieces (over a light table) and essentially stripped them together like a pressman might do to create a plate for offset printing. (Another employment adventure during my lifetime)
Now that I have completely confused more people then I have helped I guess I will finish. All of this technology talk doesn't really mean much. I work in a 10'x10' shop with dirt floors. when it rains there is a mini creek running through it.
So to finish up my way too long reply, Just use whatever patterns you can. Trace them if you need to. Just get the pattern on the wood so you can get it to the saw. Then post a photo of what you cut. I am a visual person and like to see the pictures.
Thanks
