I've tried both inkjet and "digital offset" printing and both were unsatisfactory. Process color (CYMK) and fine lines are a poor combination because the halftoning process creates the appearance of a broken line where you wanted a fine solid line. It really needs to be run on an offset press with spot colors to look right. PDFs made for print often don't look right on screen, since free PDF viewers don't handle spot color overprinting correctly. These seem like small issues, but having some experience in graphic design, they stick out. I'm still considering what to do with this project, including the PDFs.
This type of graph paper isn't for plotting data points, it's for understanding systems. I'm pretty fast with LTspice, but I reach for this chart for first-pass understanding of passive networks. I'm not sharp enough to figure out resonance frequencies, characteristic impedance, and Q factor in my head and this gets me the answer quick. What happens if a R/L/C value changes? I can compare the result immediately, compared to several clicks and keystrokes to re-run a simulation. I also like having a physical sheet of paper to markup and come back to later.
