Using color in publication is not as easy as it seems. For color printing, the greatest problem is that the color you see on a screen is not the color you get on paper. Very often, the printed color on paper looks quite different from what you see on a screen. Because of the different color models in monitor and printing system, these color models do not cover the same color gamut.
In fact, some bright colors that display beautifully on screen like vivid orange and bright green cannot be printed on paper. On the other hand, some colors that look fascinating on paper such as yellowish green or grayish blue may look oddly on a screen. As a result, you may have to re-select it many times until you finally get the colors close to what you want.
These color problems may not be an issue if your job is to produce a few signs or brochures from your inkjet or color laser printers. Because you can print them repeatedly until you finally get the satisfied result.
For a large-scale printing, we need to send our artwork to a favorite commercial printer for offset printing. Normally, offset color printing uses four-process colors: Cyan, Magenta, Yellow, and blacK (CMYK). Here comes the real problem, the color from offset printing is significantly different from our in-house printing, unfortunately.
Too many color choices
Although you can choose unlimited colors from millions of colors in the color spectrum, sometimes these too many color choices are the problem. You may not know which colors are suitable for your design. In addition, you cannot be sure that the colors you have chosen will go well together. Moreover, you still need to check the outcome of those colors in the final print.
