Prepress techniques: image processing of images of people of different ages
When it comes to high-end printed materials such as picture books and photo albums, the quality of character printing plays a crucial role. Achieving the best results requires not only advanced printing techniques but also a deep understanding of color behavior and skin tones. Based on our experience, we've compiled these insights to help fellow printers improve their output. Each original manuscript has its own unique characteristics, and the final visual effect can vary significantly depending on the subject. During pre-press preparation, it's essential to tailor the processing based on the specific requirements of each piece. For instance, when working with human skin, the goal is usually to achieve a natural and realistic appearance, with smooth textures and subtle details. The way we handle color separations can differ depending on the age of the subject. For children, whose skin is typically soft and delicate, we recommend increasing the magenta and yellow dot percentages beyond 30% (covering more than two-thirds of the skin area). These colors should remain consistent across the image, while the green channel should be kept below 10% to avoid unwanted color casts. Ideally, the black plate should be minimized, especially for non-black subjects, to maintain a fresh and healthy pinkish tone that reflects youthfulness. For young adults, the skin tends to have a slightly warmer tone. In this case, the magenta and yellow dots should be set below 45% (again covering most of the skin area), with green kept under 15%. The black plate should only appear in the shadows, avoiding midtones and highlights to preserve a clean and vibrant look. With older individuals, the skin is often rougher and darker. To reflect this, the dot percentages in all color plates may need to increase, particularly in the green and black channels. However, the green plate should still be limited to around 30% to prevent an overly cool or unnatural appearance. The black plate should only be used in the mid and dark tones, and its presence should be carefully controlled to avoid over-darkening the image. By adjusting these parameters based on the subject’s age and skin type, we can ensure that the final print captures the intended emotion and aesthetic. These guidelines are not rigid rules but rather a starting point for achieving consistent and high-quality results in professional printing.
