Pad printing (also called tampography) is a printing process that can transfer a 2-D image onto a 3-D object (e.g., a ceramic pottery). This is accomplished using an indirect offset ( gravure ) printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate .
Color targets such as the ColorChecker can be captured by cameras and other color input devices, and the resulting images’ output can be compared to the original chart, or to reference measurements, to test the degree to which image acquisition reproduction systems and processes approximate the human visual systems.
An electronic pocket calculator with a seven-segment liquid-crystal display (LCD) that can perform arithmetic operations A modern scientific calculator with an LCD. An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state ...
Without dithering, the colors in the original image would be quantized to the closest available color, resulting in a displayed image that is a poor representation of the original. The very earliest uses were to reduce images to 1-bit black and white. This may have been done for printing even earlier than for bit-mapped video graphics.
Color management is necessary because different devices have different color capabilities and characteristics. For example, a monitor may display colors differently than a printer can reproduce them. Without color management, the same image may appear differently on different devices, leading to inconsistencies and inaccuracies.
The cell colors used do not indicate how feature-rich a certain image file format is, but what density support can be expected of a certain image file format. Even though image manipulation software can optionally set density for some image file formats, not many other software uses density information when displaying images.
This limitation was addressed in 2001 with the release of PDF Reference 1.5 and Tagged PDF, [29] but third-party support for this feature was limited until the release of PDF/UA in 2012. Many products support creating and reading PDF files, such as Adobe Acrobat, PDFCreator and LibreOffice , and several programming libraries such as iText and FOP .
With half-tonning techniques, however, such a printer can produce acceptable grey-scale images too A color printer can produce images of multiple colors. A photo printer is a color printer that can produce images that mimic the color range (gamut) and resolution of prints made from photographic film.
