kohdistusmerkit

Kohdistusmerkit, often translated as registration marks or crop marks, are essential visual aids used in the printing and graphic design industries. They are typically thin lines printed on the edges of a sheet of paper or film, outside the intended trim area of the final printed piece. Their primary function is to ensure precise alignment of different colors or layers during the printing process.

When a document is printed using multiple ink colors, each color plate must be perfectly aligned with the others. Kohdistusmerkit are printed on each of these plates in the same location. A printing press operator uses these marks to visually confirm that all the plates are correctly superimposed, preventing misregistration where colors appear out of sync, creating blurry or undesirable effects.

Beyond color registration, kohdistusmerkit also serve as guides for trimming the printed material to its final size. These are often called trim marks or crop marks. They indicate the exact points where the paper should be cut after printing. Designers include these marks in their digital files, and the printing software renders them on the print layout. The printer then uses these lines to guide their cutting equipment, ensuring clean and accurate edges on the final product, such as brochures, posters, or business cards. In essence, kohdistusmerkit are crucial for achieving professional-quality printed output.
