fotopapíru

Fotopapír is a specialized paper designed for the printing of photographs. It typically consists of a paper base coated with one or more layers of photographic emulsion, which contains light-sensitive silver halide crystals. When exposed to light through a negative or digital printer, these crystals undergo a chemical change that forms the image.

The type of paper base and the coatings can vary significantly, influencing the final appearance and quality of the print. Common base materials include resin-coated (RC) paper, which is more water-resistant and dries faster, and fiber-based (FB) paper, known for its archival qualities and tonal range, though it requires more careful handling.

The emulsion layer is crucial. It determines the sensitivity of the paper to light and the range of colors or tones it can reproduce. Different types of fotopapír are optimized for different printing processes, such as traditional darkroom printing with enlargers or modern inkjet and dye-sublimation printing.

Inkjet fotopapír, for instance, features a porous inkjet coating that absorbs ink precisely, allowing for vibrant colors and sharp details. These papers come in various finishes, including glossy, semi-gloss (luster or pearl), and matte, each offering a distinct aesthetic.

The choice of fotopapír impacts the longevity, color accuracy, and overall look of a photograph. Professional photographers and consumers alike select specific types of fotopapír based on their intended use, desired aesthetic, and the printing technology available.
