Blueprint
Cyanotype blue: white lines on a deep blue ground.
Controls
- ground
- A colour, #12395b by default.
- line
- A colour, #e6edf2 by default.
- weight
- Which tones become a line. The print is two-tone by nature — everything darker than this is drawn, the rest is ground
- bleed
- How far the line spreads in contact printing. This is where the whole softness of the edge comes from
- wash
- Blotches from uneven developing. They only lighten the ground — a blueprint has no dark stains, there is nothing there to add
- fade
- How far the edges of the sheet have faded, the way an old print bleaches from the border inward
- grid
- Strength of the drafting grid printed under the drawing
- grid step
- Distance between the grid lines
- contrast
- A number from -1 to 1, 0 by default.
