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 inch

The dot per inch (DPI) is the standard resolution metric for printed output, specifying how many individual ink or toner dots a printing device places per linear inch. Unlike a pixel, a printed dot is a physical deposit of ink variable in size and subject to dot gain (ink spread into substrate). Inkjet photo printers: Epson SureColor SC-P900 up to 5760 DPI; HP DesignJet Z9+Pro at 2400 DPI. Laser printers: HP LaserJet standard 600 DPI; enterprise class 1200 DPI. Offset CTP plate imaging: 2400-3600 DPI. Rule of thumb: required DPI ≥ 1.5 × LPI for acceptable halftone; ≥ 2 × LPI for high quality - a 175 lpi magazine job needs ≥ 350 DPI raster data. Thermal dye-sublimation printers achieve continuous-tone output at 300 DPI because dye diffuses to fill each cell. As a dimensional unit, 1 DPI = 1 PPI; DPI implies physical print output. 1 DPI = 2.54 dots/cm = 25.4 dots/mm.
