Why are planplots with a large area application charged more expensively? From which color portion does the higher price apply?

From 30% coverage of the plan with solid areas or an analogously high number of printed pixels, plots are assessed as flat and the higher price is charged for this. The ink coverage of such plans is many times higher, which justifies the higher price.

An extreme example is the comparison of a square of 10 cm side length with a line thickness of 0.25 mm. In case the square is only outlined, the ink coverage is 100 mm² (4 x 100mm x 0.25 mm). If the square is filled, the ink coverage is 10’000 mm² (100mm x 100mm), which is 100 times more. Normal blueprints have an average coverage of 5-15%.
