![]() Higher values, on the other hand, create a simpler composition, often ignoring smaller areas of color and combining them into adjacent colors for larger, single-color path areas. Lower values create many more paths, making the document more complex and more likely to choke a printer’s processor, but low values also increase the fidelity of the vector to the original raster image data. Minimum Area is the smallest path size desired. ![]() To avoid creating vector paths that look pixelated, increase the value of Path Fitting until the resulting paths are smooth, without losing crisp edges and color breaks. ![]() For example, a setting of 1 px on a low-resolution image will create vector paths that perfectly stair-step with the grid-based, square pixels. Path Fitting The control determines how closely the vector paths should match the edges of color areas in the source image. When you enlarge a raster file with pixel-based art too much, the edges look jagged and the quality is lost. When Strokes is selected, the Max Stroke Weight and Min Stroke Length controls are activated providing the options for, respectively, the maximum thickness at which a stroke may be rendered before it’s converted to a fill area and the shortest length of object acceptable as a stroke. In comparison, raster art (also referred to as bitmaps or raster images) is created using colorized pixels. If you haven’t opened a library, your only choice will be Automatic, meaning Illustrator will build colors as needed depending on the Max Colors option.įills and Strokes, checkboxes under Trace Settings, determine whether to render vector objects as fills, strokes, or both. However, if you’ve opened a pre-set swatch library such as a Pantone or Toyo, that library will be listed too, enabling you to target all your tracing colors to fit within those in the library. Palette This pulldown menu says Automatic by default. For example, if you set Threshold to 200, all the image’s shades of gray that are 200 or higher (on a scale of 0-255), will be white in your black and white tracing all values lower than 200 will become black. You can enter a numerical value or use the slider bar that appears when you click the arrow on the right. Threshold If you chose the black and white mode, the Threshold field becomes active, allowing you to set the maximum grayscale value of white. Yes the document will most likely be viewed on the web, so you may want to consider using a screen-friendly font (sans-serif font), but for laying out your Illustrator documents, continue as though it's going to be printed on paper.Mode This pulldown menu lets you choose whether your image and/or the tracing you want is color, grayscale, or strictly black and white. What do I do?ĭesign as though it's print. You can resize, rescale, and reshape vectors infinitely without losing any image quality. With vector image files, resolution is not an issue. If the image becomes blurred or pixelated, it’s most likely a raster file. My Dissertation is going to end up as a PDF - that's electronic, but PDF is also print-friendly. An easy way to tell if an image is raster or vector is to increase its size. Don’t leave it to chance, instead use the program as it’s intended to be used. Yes printing 0 255 0 for RGB will print out a green color, but maybe it won’t match the evergreen color you were aiming for. So why should you care? By setting up your document to specifications that match your printer or monitor’s display, you are maintaining artistic control over how the end result will look. In this day and age, we don’t have to use printers with just four colors, and software such as Illustrator will allow a document set to RGB to be printed with ink. As in, this is going to be printed with Color in K - so I need to use CMYK. CMYK is the best choice for any output that will be physically printed.Īs a partial mnemonic, think of K for INK. (Such as the white of the paper before you print on it). CMYK is a “subtractive” color model because as you remove colors you’ll see white. RGB is the best choice for any output that will be displayed on a computer monitor.Ī partial mnemonic could be “R” for ray as in rays of light on a monitor.ĬMYK stands for: Cyan, Magenta, Yellow, Blackīlack was called “Key” in print shops because it held the key information in a print, and the name stuck. RGB colors are called “additive” color model because if you add all three colors, you’ll see the color white. RGB pertains to the light given off by computer monitors.
