The four basic inks to a full range colours found in four colour printing are identified as: (A) range colours (B) premium colours (C) process colours (D) production colours Correct Ans: (C) Explanation:In four-colour printing, professionals rely on process colours—cyan, magenta, yellow, and black (CMYK). These four inks combine to produce a wide range of colours used in modern printing. They form the core of almost every vibrant image seen in magazines, newspapers, and packaging. Each ink plays a unique role. Cyan, magenta, and yellow act as the primary subtractive colours. When printers apply them in varying intensities, they generate diverse hues and tones. Black (K), however, adds contrast and clarity. It helps create sharp edges and deep shadows, which the other three cannot achieve alone. Moreover, printers use halftone techniques to arrange these inks as tiny dots. These dots vary in size and pattern. When viewed from a distance, they blend seamlessly. Consequently, the final image appears smooth and full of detail. Compared to alternatives, process colours offer consistency, affordability, and efficiency. Terms like “range colours,” “premium colours,” or “production colours” sound technical. However, they do not refer to the standard four-ink printing system used in publishing. Because of their reliability, CMYK remains the go-to choice for mass production. It ensures the same quality across thousands of copies. Additionally, it's compatible with most commercial printers. In conclusion, understanding process colours is crucial in print media. These inks not only shape how visuals appear but also influence how audiences perceive printed content. For anyone working in media production, mastering this system leads to sharper designs and stronger communication impact.
