What UPSC Asks About Printing / Colour Technology
UPSC’s solitary 2006 Prelims question on Printing and Colour Technology shows the commission’s tendency to blend basic science with daily utilitarian gadgets. Aspirants should master additive (RGB) versus subtractive (CMYK) colour models, primary–secondary colour mixing, and the physics of pigment absorption and light reflection. Equally important are printing techniques—offset lithography, gravure, flexography, inkjet and laser—and the role of photosensitive plates, toner and dpi resolution. Questions can also pivot to colour blindness tests, colour temperature in digital displays and environmentally friendly soy-based inks. Keeping track of Bureau of Indian Standards norms, anti-counterfeiting security inks and recent 3-D printing updates will future-proof your preparation.

Frequently Asked Questions
Which colour model—RGB or CMYK—should be linked to computer monitors in an UPSC MCQ?▼
Monitors and televisions use the additive RGB model because they emit light, whereas printed material relies on the subtractive CMYK model where pigments absorb light.
Are 3-D printing questions classified under this sub-topic?▼
Yes. UPSC often brackets additive manufacturing with Printing Technology, so learn filament materials, layer-by-layer deposition and India’s National Strategy on Additive Manufacturing.
