# inkPreflight > inkPreflight is a measurement-based preflight QA tool for tattoo artists. Upload a design and it measures minimum line width (mm), line spacing, black-fill density and merge risk at the real tattoo size, then flags lines that will blur, blow out or merge once healed. It also generates a 1:1 real-size stencil PDF. ## What it does - Measures thinnest line width in millimetres at the target tattoo size - Detects lines and gaps below safe tattoo thresholds (fine-line, lettering, blackwork) - Produces merge-risk maps, width/density heatmaps and artist/client QA report PDFs - Exports a 1:1 and mirrored real-size stencil PDF ## What it does not do - It does not predict healing outcomes or replace artist judgement; it reports geometry only. ## Plans - Free: 5 analyses/month (no card) - Pro: USD 19/mo, unlimited - Studio: USD 59/mo, multi-artist + API ## Links - Home: https://inkpreflight.com - Pricing: https://inkpreflight.com/en/pricing - Contact: https://inkpreflight.com/en/contact
