Re: why do photos need color correction prior to printing ?

But the question OP is asking is WHY does the monitor need to be calibrated to match the print if it doesn't need to be calibrated to make the camera download look good on screen? The answer is simple. I will guess OP is outputting JPEGs from his camera. These are highly modifed in the camera with a certain end appearance target. Since most photographic observation is web and monitor based these days, and relatively few monitors are calibrared the JPEG is optimized for viewing under normal, non-calibrated conditions.

The imprecision inherent in the system from monitor to monitor is not an isssue for most consumers. But reliable printing requiees precision. Once the monitor is calibrated to show true color and brightness, the consumer JPEG is all wrong. If OP worked with RAW, he wouldn't have to ask his question. Every image would need to be processed to look good on any monitor, especially a calibrated one. You would just adopt a post processing formula that worked for you.

That leaves just the question of why (sometimes at least) drugstore prints match what you saw on your uncalibrated monitor. Making that match is the business of consumer printers. They have to adjust the images in-process to make them look good, no matter how they were processed in the camera or in post processing. Sometines they succeed, sometimes they don't. Rigorous home and professional printers want to succeed 100% of the time and so rely on rigidly calibrated systems and reproducible workflow.
