Halftone

Halftone refers to a printing technique used to reproduce continuous-tone images, such as photographs or gradients, by breaking them down into a series of dots of varying sizes. These dots simulate different shades of gray or color when viewed from a distance, creating the illusion of continuous tones.

Recommendations

1. Resolution: Select an appropriate halftone screen ruling based on the printing method and substrate to achieve optimal image quality and detail reproduction.
2. Dot Shape: Choose a halftone dot shape (e.g., round, elliptical, or square) that suits the printing process and substrate characteristics, balancing image fidelity with printability.
3. Color Separation: Use halftone screens and color separation techniques to convert continuous-tone images into printable halftone separations for each color channel.
4. Contrast Enhancement: Adjust the halftone dot size and spacing to optimize image contrast and detail reproduction, enhancing the visual impact of the printed image.
5. Proofing: Perform thorough proofing and color correction to ensure accurate reproduction of halftone images across different printing devices and substrates, minimizing variations in color and tone.
