Calculate glaze batch weight from unity formula and raw material analysis. Scale recipes to any batch size for consistent studio pottery glazing.
Create kiln firing schedules with ramp rates, hold times, and cone temperatures. Plan bisque and glaze firings for electric and gas pottery kilns.
Calculate clay shrinkage percentage from wet, dry, and fired dimensions. Plan pottery sizes accurately for clay bodies from leather-hard through glaze firing.
TAC is the sum of C+M+Y+K dot percentages at a given point, capped at 300–400% depending on substrate. Average page coverage drives ink consumption more than peak TAC.
TAC = C% + M% + Y% + K% (per pixel, max ~300%)ISO/IEC 24712 defines five test pages averaging roughly 5% coverage per CMYK channel (20% combined) for typical office documents. Marketing collateral often runs 15–40% average coverage.
Ink per page ≈ Rated yield × (Actual coverage / ISO coverage)Divide cartridge or ink set cost by rated page yield at ISO coverage, then scale by actual coverage ratio. Add waste factor of 5–10% for cleaning cycles and startup.
Cost/page = (Cartridge cost / ISO yield) × (Coverage / 5%) × Waste factorUpdated: July 2026
Black-and-white text document at ~5% K coverage on letter size. A 3000-page toner cartridge at ISO 5% yield delivers near-rated page count with minimal color ink use.
Marketing flyer with photos averaging 40% combined CMYK coverage. Ink consumption is roughly 8× ISO standard — a cartridge rated 2500 pages yields ~300 copies.
Poster with near-solid black background at 95% K coverage consumes roughly 19× the ink of a 5% ISO page. Budget ink cost accordingly and verify substrate limits for heavy ink laydown.
A small solid logo does not mean the whole page is 100% covered. Calculate area-weighted average coverage across the entire page for yield and cost estimates.
Sum all four channels at the darkest point. Setting all channels to 100% gives 400% TAC — far over limit. Use rich black recipes and correct photo separation for the substrate.
Ink and toner costs depend on how much of each page is covered and at what density. Commercial pricing often uses ISO coverage standards or total area coverage (TAC). This calculator estimates ink usage and per-page cost from coverage percentages and job volume.
