Angle: The angle allows you to rotate the cell on the page.On a CMYK device, this means 25 x 25 x 25 for CMY and Fiery LLC recommends not using K (black) unless it is needed for shadows.A 5x5 cell can display 5 x 5 = 25 shades. ![]() The number of shades per cell is determined by the size of the cell: (Resolution /LPI)^2.Increasing the LPI results in fewer shades but appears more consistent and the cell is hidden.This can create the effect of a lower resolution. A lower LPI results in bigger cells and more shades.This can create a polarization effect on objects that use many colors. A higher LPI results in smaller cells with fewer shades.Higher resolution devices allow for higher LPI, but the best LPI depends on the resolution of the output device and what you are printing.At 600 DPI, this would give you a cell size of 10x10 pixels (600/60).At 300 DPI, this would give you a cell size of 5x5 pixels (300/60).A frequency of 60 LPI = 60 cells every inch.Frequency (LPI): Measured in Lines Per Inch (LPI), the frequency is the number of halftone cells per inch.It is important to know what composes a cell: Devices with higher resolutions have more effective screening and can produce more colors. To generate the effect of thousands of colors, the dots are arranged in a process called screening. Most printers are 1-bit devices - they only have one shade of each primary CMYK - so they can put down the dot or not. Shadows (90-100%) - larger dots, darker shades, more coverage.Highlights (0-10%) - smaller dots, lighter shades, less coverage.When working with halftones, it's important to distinguish the tint regions: Dot Shape: Dots can be a wide variety of shapes and selection depends only on your opinion of which one produces the best detail.A cell is a square group of pixels and its size is determined by the frequency (LPI).Įach color separation is a halftone using a single ink, a gradient dot pattern is applied and the shades (tints) are created by the dots. They are controlled by three parameters: frequency (LPI), angle, and spot function, which together make up a cell. Halftones are images composed of dots rather than continuous tones. ![]() Separations, Halftones, and Cells Explained Part I: Selecting Pages and Viewing Raw Data ![]() For higher resolution prints, greater accuracy is required. A best practice is to test your ink for placement accuracy and density. The separation halftones are configured individually and then aligned to form a final image. Separations can be created from various file types or in a design application and imported. To produce photo-realistic prints, prepare the job as a set of CMYK separations, which use halftone dot screening and result in ink reduction. Separations and Halftonesįilm separations are printed onto a clear film and are used for screen printing, offset printing, sandblasting, and other applications. Note: These materials are offered only in English as supplementary examples for a deeper dive into Fiery LLC products. Moreover, you can keep default options to be used for new files, all colors, and backgrounds instantaneously as you change them.Supplementary English-Only Training Materials The EZ-screen can reduce your film/screen count to only 3 or 4 colors, instant preview feature, full-featured trapping systems, halftoning, and save films with master/slave settings. Above all, it enables the conversion of multichannel images and CMYK into a fixed ink set. The complete chromatic range is excellent for optimizing images for inkjet printing. It is designed to optimize the screen printing process and has an independent set of spot color separation. The Xerio Sep is one of the easiest, fastest, reliable, and best color separation software for screen printing found by GRAFCOAST. Furthermore, the developers also provide several other tools and software for screen printing. It converts RGB images to multi-channeled images for screen printing. The YRBGK color separation software is a plug-in for Photoshop and offers nearly all the features you need.
