About Pixels per yard

The pixel per yard (px/yd) is an imperial resolution unit used in textile printing, wide-format graphics, and fabric digitising, where roll widths and run lengths are measured in yards. The yard is exactly 0.9144 m = 36 in (Weights and Measures Act 1963; NIST Handbook 44), giving 1 px/yd = 1/36 PPI ≈ 0.02778 PPI. Wide-format inkjet printers (Roland RE-640, Mimaki JFX200) resolve up to 1440 DPI = 51,840 px/yd. Fabric digital printers for dye-sublimation operate at 300-600 DPI ≈ 10,800-21,600 px/yd. Flag and banner printing standard for photographic quality at 1 m viewing distance is ≈ 720 px/yd. 1 px/yd = 1/36 PPI ≈ 0.027778 PPI ≈ 1.111 px/m.

About Dots per point

The dot per point (dot/pt) expresses output resolution relative to the PostScript point - exactly 1/72 inch, codified by Adobe in the PostScript Language Reference (1985). The Apple Macintosh 128K (1984) ran its built-in CRT at exactly 72 DPI, placing 1 dot per point - an intentional WYSIWYG design: a 12-point character on screen measured 12 pixels tall and printed at 12 points on the Apple LaserWriter. Device resolution milestones: Apple LaserWriter (1985) 300 DPI = 300/72 ≈ 4.17 dot/pt; HP LaserJet 4 (1992) 600 DPI ≈ 8.33 dot/pt; Linotronic 300 imagesetter (1985) 1270 DPI ≈ 17.64 dot/pt; Agfa Selectset 5000 at 2400 DPI = 33.33 dot/pt. TrueType and OpenType font hinting instructions align outline points to raster device pixels at the current dot/pt ratio. The CSS pt unit equals the PostScript point: 1 CSS pt = 1/72 CSS in = 4/3 CSS px at 1 dppx. 1 dot/pt = 72 DPI = 72 PPI.
