Glossary Of Printing Terms [6]

U Uncoated Paper Paper which is not coated with an agent which improves brightness or printing properties. Uncoated paper is typically used for letterheads, copy paper, or printing paper.
Undercolor Removal (UCR) Method of making color separations such that the amount of cyan, magenta and yellow ink is reduced in midtone and shadow areas while the amount of black is increased.
Universal Copyright Convention (UCC) Alongside with Berne convention, one of the two principal international conventions protecting copyright. It was adopted in Geneva, Switzerland in 1952. Today it has lost its significance since almost all countries are either members or aspiring members of the World Trade Organization (WTO), and are thus conforming to the Agreement on Trade-Related Aspects of Intellectual Property Rights Agreement (TRIPS).
Unsharp Masking An image sharpening technique, often available in digital image processing software. The "unsharp" of the name derives from the fact that the technique uses a blurred, or "unsharp" negative image to create a mask of the original image. The unsharped mask is then combined with the positive (original) image, creating an image that is less blurry than the original. The resulting image, although clearer, may be a less accurate representation of the image's subject.
UV Coating UV coating, or ultraviolet coating, is a very glossy, shiny liquid coating applied to a printed paper surface and cured on a printing press or special machine using ultraviolet light. The coating hardens, or cures when it is exposed to ultra violet radiation.
UV DTF UV DTF stands for UV Direct-to-Film, which is a printing method used for transferring designs onto various surfaces, particularly textiles. It involves printing the design onto a special film using UV-curable inks, which are then transferred onto the desired material using heat and pressure. This technique offers vibrant and durable prints with excellent color accuracy and detail. UV DTF is commonly used in the garment and textile industry for creating custom prints on fabrics.
