1. Operation data
Internal number: OB_022
Operational regime: Translation Between Representation Systems
Source image: Photograph
Operational description:
The photographic image is converted into four CMYK channels, each reconstructed using a dot screen with a different angle. The dot size varies according to the amount of ink in each area, and the four channels are recomposed into a new image.
2. Tools and procedure
Tools / medium:
- Script
Technical procedure:
The image is converted to CMYK, a dot screen is generated for each channel, and the four channels are then recomposed into a final image. Cell size, dot scale, and rotation angle of each CMYK channel. The cell size controls the loss of detail and the scale determines how much the dots expand.
3. Variables
Controlled variables:
- Screen cell size (
cell_size). - Scale or diameter of the dots (
dot_scale). - Rotation angle of each CMYK channel.
Uncontrolled / accidental variables:
- Appearance of moiré patterns.
- Chromatic overlapping and interference between channels.
- Irregular loss of detail in contours and transition areas.

6. Crisis and formal-perceptual reading
Main crisis:
The operation affects the visual grammar of the image: shape, contour, color, figure/ground relationship, legibility, recognition, and support:
The CMYK screen replaces photographic continuity with a structure of overlapping dots. As the halftone size increases, the shape fragments, contours lose precision, and color separates into chromatic interferences. The figure begins to merge with the background until its recognition becomes difficult. The visual support is also transformed: the image ceases to be perceived as a continuous photograph and appears as a graphic printing surface.
7. Final evaluation and artistic reference
Operation notes / what I learned:
By increasing the size of the screen, the image loses detail and the figure blends into the background. The halftone shifts from being a texture to dominating the image.
