DPI & PPI

Definisi

DPI (titik per inci) mengukur resolusi keluaran cetak; PPI (piksel per inci) mengukur resolusi tampilan layar — keduanya menggambarkan kerapatan spasial elemen gambar.

Penjelasan

Print at 300 DPI is considered photo quality; newspaper print runs at 85–150 DPI. Apple coined 'Retina display' for screens above ~300 PPI, where individual pixels become imperceptible at normal viewing distance. The iPhone 15 Pro screen is 460 PPI. Confusingly, 'DPI' is widely misused to mean PPI in software settings—they are conceptually distinct but numerically interchangeable in digital-to-print workflows.
