Conventional halftones, often referred to as AM screens (amplitude modulated), distribute ink over a grid of dots that increase in size for darker tones. Throughout the tone scale, the frequency of dots remains the same, but the size or amplitude increases. The ink and water requirements vary greatly throughout the tonal range, causing a basic lithographic instability for which there are no on press controls. (more…)
Halftone screen angles With the exception of FM (stochastic screening), all screens consist of dots arranged in a regular pattern or matrix. The vertical and horizontal distance between successive dot centers is constant and is a function of the screen frequency. (more…)
TheVectorLab was born in 2008 out of the philosophy that it’s important to spend LESS time in an office sitting at a computer… and MORE time hanging out with family, friends, and being outside in nature. If you have the right tools to help you work more efficiently, then you can put that extra energy and focus towards things that really matter. (more…)
If a POD printer asks you to submit 300dpi grayscale images from which they can make halftones, it does not mean that output is going to be 300dpi, or that the 256 shades of gray you see in each pixel of your computer screen are going to show up in the output. In fact, there are no shades of gray in the interior of a book; gray is simulated with black dots of different sizes. (more…)
