Untreated iPad displays feature chemically strengthened aluminosilicate glass finished with a slick, oleophobic fluoropolymer layer. This smooth surface generates minimal drawing friction, allowing factory nibs to survive well beyond two years under standard note-taking routines. Many digital illustrators, however, hate that skating sensation and install micro-etched, matte screen protectors to introduce physical tooth.
That tooth comes at a measurable mechanical cost. Brands like Paperlike disperse microscopic PMMA plastic beads or chemical acid-etch pits across the protective sheet to simulate fibrous pulp paper. This micro-texture shears down soft thermoplastic nibs like a fine-grit sandpaper block. Digital artists working 20 to 30 hours per week on matte protectors often exhaust a fresh nib within eight to twelve weeks.
If you favor paper-finish screen protectors, inspect your stylus tip bi-weekly under directional light. Watch for flattened drafting planes or thin polymer walls along the perimeter. Rotating the pencil periodically distributes wear patterns evenly across the circumference, staving off premature point perforation.
