However, because of the complicated process, spot colors are effective at preventing forgeries of money, passports, bonds and other important documents. Now these days, spot color are use generally for the cost and potential for problems for a print job increase as one adds more spot colors, due to the increased cost and complexity of added process inks and films, and requiring more runs per finished print. Spot lamination and UV coatings are sometimes referred to as ‘spot colors’, as they share the characteristics of requiring a separate lithographic film and print run. The dot gain, hence the screen angle and line frequency, of a spot color vary according to its intended purpose. All the areas of the same spot color are printed using the same film, hence, using the same lithographic plate. Spot colors were created, multi-color print with a spot color process, every spot color needs its own lithographic film. Creating a pan tone Spot Color is similar in concept, but with the added need for precision. You probably mixed yellow and blue paint to get green in your youth.

And on older computers capable of displaying but 256 colors at a time, and there are still a lot of those relics around, your background will display clean and non-dithered. That’s your guarantee the color will not embarrass you when it displays on the other computer platforms. Here are some examples, If your web site has a solid colored background, make it a Web Safe color. Now lastly for web safe color you would want to know how they are used or in this case how would you go about using it. To display more colors, more RAM is needed. Most early video/graphics cards had between 128 and 512K of video RAM, or enough to display 16 to 256 colors. There were many reasons for these color limitations, the high cost of video RAM being the foremost. Back than most computers were only capable of displaying a maximum of 256 colors at one time. Now we need to get a better understanding in when, where and why web safe color was created. Now why is that you maybe wondering? Well the discrepancy is similar to what happens when a Windows user opens a word processor document created on a Macintosh and sees a lot of odd characters in place of the expected punctuation marks and other extended characters. Now you maybe curious to why this palette can only contain 216 colors in total, instead of the maximum 256 colors, is that only 216 out of the basic 256 colors will display exactly the same on all computers. Web safe colors have about 216 colors that display solid, non-dithered, and consistent on any computer monitor, or web browser, capable of displaying at least 8-bit color (256 colors).
