Print Photography Quiz: Resolution and Color Management

300 pixels per inch at the intended print size is the threshold where individual pixels become invisible at normal reading or viewing distance. Below this number, pixel structure becomes visible and detail looks coarse.

Soft proofing applies a simulated view of how a printer-paper-ink combination will reproduce the image, revealing where colors will shift or saturate before you commit to printing. It is the most cost-effective way to reduce failed prints.

Paper surface affects how ink is absorbed and how light is reflected. Glossy surfaces amplify perceived contrast and black density; matte surfaces scatter light and reduce apparent contrast; textured surfaces add their own visual quality to the image.

Matte paper scatters light from its rough surface, and ink soaks slightly into the coating. Both lower contrast and stop the blacks from getting as deep as on glossy paper, whose smooth surface keeps ink on top and gives richer, darker shadows.

Prints come out dark when the editing screen is too bright, because you set the file's tones by eye on that screen. Lowering the monitor's brightness to a print-friendly level, then brightening the file to match, brings the print closer to what you see.

When colors from a source space fall outside the destination space's gamut, they must be remapped to a reproducible value. Rendering intent determines whether that remapping compresses the whole palette proportionally or simply clips each out-of-gamut color to its nearest in-gamut equivalent.

A printer profile describes the specific color behavior of a printer, ink set, and paper combination. Sending that profile to a color management engine allows it to convert file colors to the exact ink values needed to reproduce them accurately on that output.

An embedded profile tells a print lab which color space the file values are expressed in. Without it, the lab must guess, and an incorrect assumption will shift all colors in the final print. Embedding removes that ambiguity.

JPEG is widely accepted for standard lab prints and is smaller to transfer. TIFF is preferred when the lab needs maximum bit depth and no compression artifacts, such as for fine art printing or large-format output.

Print outputs have a lower effective resolution at viewing distance than screens, and the printing process introduces a degree of physical softness in ink absorption. More sharpening at export compensates for this and restores the crispness visible on screen.

The farther away a print is viewed, the less fine detail the eye can resolve. A billboard seen from across the street needs far fewer pixels per inch than a small print held in the hand, and it also looks sharper at that distance.

A print only reflects the light falling on it. How bright it looks depends on the paper's whiteness and reflectivity and how much light is in the room. That is why a print can look dark in a dim room even if the file is correct.

A white or neutral border frames the image, protects edges during handling, and gives a visual pause between the photograph and its surroundings. It also provides a surface for matting and framing without touching the image itself.

A proof print on the actual paper and printer to be used for the final output verifies that color conversions, rendering intents, and paper profiles have produced the expected result before committing to a full print run.

Successful printing is primarily a color management challenge: ensuring that what the monitor displays is accurately translated through profile conversions into the ink values that reproduce the intended tones and colors on the chosen paper.
