To check where spot colors are used, open the Separations Preview panel, turn on separations, and then click the eyeball next to CMYK. Anything remaining on the page is in spot color. You can also choose View → Spot Color to display your document in black and white with the spots in color.
Spot colors are used when you need to distinguish one item from another within an otherwise uniform set of colors. For example, if you were printing t-shirts for a school fundraiser, you might want to use a specific color for each shirt. Or perhaps you are creating labels for bottles of perfume; here, too, it makes sense to use different colors for each product line.
Spot colors take up space in your InDesign file and printing buffer. The more intense the color, the larger the file size and longer it takes to print. If you don't need to use spot colors, try reducing the amount of detail within the artwork by using a soft brush or low opacity paint bucket fill.
Select Edit color from the menu by clicking the tiny arrow button on the palette. Choose Treat as: Spot after selecting the color swatch inside the dialog box. This swatch will now appear as well as standalone as a spot color. You can also call this color scheme Dark Turquoise/Light Green.
The Pantone library, or Pantone Matching System (yep, that's PMS for short), is primarily used to specify spot colors. RGB colors, which stand for Red, Green, and Blue, are utilized for on-screen viewing. The four printing colors utilized in the majority of full-color items are known as process colors. These include Cyan, Magenta, Yellow, and Black.
Spot colors are pure colors that are added during manufacturing. For example, red might be specified as a spot color for both the foreground and background of an item. Process colors can be mixed together at varying ratios to produce nearly any other color. For example, cyan (the blue-green color) can be mixed with magenta (the red color) to create green. Or, black can be added to any color to make it disappear entirely. Spot colors are usually more expensive than process colors because they require special orders that push back production schedules.
Spot colors are useful for adding detail or variation to products that will not be seen under normal lighting conditions. They can also be used when there is no suitable process color available. For example, Pantone may have red, but it could be any one of several different shades of red. It would be difficult or impossible to mix enough quantities of red ink to match all those variations with the process colors currently available. Specifying a single spot color allows you to use a single order to receive everything needed to make that color.
Using spot color inks instead of CMYK (cyan, magenta, yellow, and black) printing is one option. A spot color is when an ink (such as a spot color green) is used instead of a blend of yellow and blue as in CMYK printing. Spot colors are useful if you want to create a specific color that isn't available in the four main CMYK inks.
The downside to using spot colors is that you can only use ones from the list of approved manufacturers. If you want to use a different color, you will have to ask the printer if they can provide it and if so, what price would be associated with it. Some printers may even charge you extra for using spot colors!
For example, red is made up of about 63% cyan, 37% magenta, and no yellow or black. Using a spot color red instead of mixing these three inks allows for much more precision when painting.
Spot colors are also useful if you want to print in a color outside the standard 498 colors that most printers offer. For example, some printers may allow you to order custom colors such as neon pink or orange. These would not be possible to produce with CMYK inks but they could be ordered by spot color.
Colors in HTML and CSS are recognized by their hexadecimal codes. If you're working on a webpage or another HTML project and want to add an element that matches a certain color in an image, website, or program window on your computer screen, you'll need to obtain the hex code for the color. There are many online tools you can use to generate random colors or find colors in images.
There are two types of color codes: named colors and RGB (red, green, blue) values. Named colors are simply those colors that are listed in web design programs or online generators. They make it easy to insert existing colors into a document without having to calculate their exact hex value. Named colors are identified by their name, which typically consists of three letters followed by six numbers. For example, the color red is called #FF0000. You can also see red as ff0000.
You can identify any color in an image using its RGB values. This is usually done with an image editing program such as Photoshop or GIMP. But you can also determine these values by hand as long as you know how each color component works. The RGB system assigns a number to each component from 0-255; 0 is completely transparent, 255 is completely white or black. An RGB value can be used as a name for the color if you wish. For example, rgb(255,0,0) is red.
Process of Solid/Spot Color Spot colors, in a nutshell, are pre-mixed inks that are applied exclusively to the area designated for each color. To print a black, brown, and red picture, pre-mixed black, brown, and red inks are utilized. These three inks can be used as the only colors used to print the picture, or they can be mixed with other colors to create new shades. For example, white can be added to darken colors like blue or purple, or yellow can be added to lighten colors like green or orange.
Red is a solid color. It cannot be mixed with other colors like blue or pink; instead, it must be printed in full strength. However, when combined with other colors, red can make a bright hue like maroon or burgundy.
The key difference between spot colors and regular inks is that spot colors are used exclusively for certain parts of the picture or design and not others. For example, if I wanted to print a shirt in red, black, and white, those would be considered three separate colors and would require me to purchase three different inks. But since red is used only in one section of the image, that could be done with just one ink. Same thing with black and white: either could be separated into its component colors or mixed together to create new tones.
In Illustrator, you can quickly check the CMYK values of a Pantone color by choosing it and examining the color palette. When you click on the little CMYK conversion icon, your CMYK values will be presented directly in the color palette. They are located along the bottom of the window next to the word "Profile."
You can also use the Color Picker to test colors in Photoshop or Fireworks. In the Color Picker dialog box, click the button next to the word "Sample" to display all the available colors. Click the word "CMYK" to view which colors are printed in what percentage of each ink.
There are several websites with a large database of printed colors. One such website is Web-Design-Examples.com. You can search for any color on the site and find out which company's printing it is most likely being used by.
Colors look different on screen than they do on paper. To make sure that you're picking up all the colors you need from your sample image, open the file in Photoshop and apply the following settings: Match Paper (Image > Adjustments > Matting) or Use Document Profile if there is no Matting option.
