Dot Gain, or dot expansion, is one of the biggest challenges in Halftoning, causing colors to appear darker and image details to blur. Controlling this phenomenon is achieved through precise calibration of CTP devices and printers based on industry standards like G7 or ISO. Implementing Dot Gain compensation curves in the prepress stage ensures that the size of the dots in the final output accurately matches the digital file.

Technical consultants recommend that Dot Gain measurements be taken periodically and for every new material type. This is particularly crucial for highly absorbent packaging materials (like craft cardboard) which are prone to higher Dot Gain. This control process not only preserves the brand’s color accuracy but also prevents printing waste and helps maintain consistency across all customer orders.
