# Line Screen

Tapered lines · needle points

A line screen prints tone with parallel lines instead of dots. Each line swells in the shadows and pinches to a point in the light. Line Screen turns your picture into that field of tapered lines.

## Controls

### Lines

- **Lines** (hero knob, 20 to 200, rests at 65). The hero. How many lines fit down the frame. Few is bold and graphic, many reads as a fine screen.
- **Angle** (Fader, -90° to 90°, rests at 30°). Tilts the lines.
- **Taper** (Knob, 0 to 100, rests at 45). How fast the lines thin out toward the light. Low keeps them full, high leaves only the shadows heavy.
- **Tips** (Switch: Needle / Blunt). **Needle** lets lines thin all the way to a point. **Blunt** cuts them off short, with square ends.

### Shape

- **Follow** (Knob, 0 to 100, rests at 0). Bends the lines with the picture's tones, so they ripple over the shapes like an engraving.
- **Rough** (Knob, 0 to 100, rests at 0). Makes the line width ragged, like ink on rough paper.
- **Drift** (Knob, 0×/loop to 4×/loop, rests at 0×/loop). The lines slide across the picture, up to four times a loop, and land back where they started.

### Tone

- **Black** (Knob, 0 to 100, rests at 0). Sets the black point. Raise it and more lines fill in solid.
- **White** (Knob, 0 to 100, rests at 100). Sets the white point. Lower it and more of the picture goes to thin points.
- **Gamma** (Fader, -100 to +100, rests at 0). Lightens or darkens the midtones before the lines are drawn.
- **Smooth** (Knob, 0 to 100, rests at 30). Softens the picture first, so lines swell in smooth curves instead of chasing every detail.
- **Invert** (Switch: Off / On). Swaps it, so the lines are thick in the light and thin in the dark.

### Ink

- **Ink** (Select: Black / Navy / Sepia / Source / Hologram). The line color. Black, Navy, Sepia, Source for the picture's own colors, or Hologram cyan.
- **Paper** (Select: White / Cream / Black / Clear). What's behind the lines. White, Cream, Black, or **Clear** to keep only the lines.
- **Glow** (Knob, 0 to 100, rests at 0). A soft halo of light around the lines, in the ink's color.

## Presets

- **Needle Screen**: Fine diagonal lines that swell to black and pinch to points in the light.
- **Engraved**: Lines that bend with the shape, like a banknote portrait.
- **Hologram Lines**: Glowing cyan lines on black, level, thin in the dark.
- **Blueprint**: Navy lines on cream, blunt ends.
- **Drifting Lines**: Lines that slide across the picture, twice a loop.
