Q&A
Why is the color matching inconsistent between days and even between the same ad on the same day?
There are many challenges when printing color ads on the press. The speed of the press and the length of the press run can affect the ink density. When the press starts, the pressroom operators are working to apply the proper amount of ink density to every page. There may be pages that are slightly lighter or darker initially. However, as the press continues to run the ink densities are set to standard.
What is Dot Gain?
Dot Gain is an increase in the diameter of the halftone dot. Dot Gain will always be present in offset printing. A 40% dot in an image may read as high as 70% when printed. This indicates a total Dot Gain of 30%. Not all dots grow at the same degree. The highest area of Dot Gain is in the mid tones (40%-50%-60%).
Should I create black using 4 colors, CMYK (rich black)?
4-color black, or rich black, is not recommended. Color can shift and misregistration of type becomes more visible.
