I make my own DX labels from slug repellent tape and insulating tape stuck to a reloadable cassette. I do it by eye looking at the spacing on pre-printed cassettes. I keep getting it slightly wrong in terms of spacing and would really like to find the actual ANSI spec somewhere, so I can know the exact measurements. I'd like to know the exact diatance from the cassette lip to the start of row 1, the distance from the cassette cap to the ground band and the exact grid cell size. As DX was introduced by Kodak and the spec is an ANSI standard, I guess it might be in inches not mm. I can't decide whether a cell is 5 mm or 0.2". I know there are a few web sites that let you print a template on paper but I'd have more confidence if I could draw my own grid based on the spec.
