This refers to the process of setting a device to known colour conditions. Calibration must be performed externally for devices whose colour characteristics change frequently. For example, monitors need to be calibrated because phosphors lose brightness over time. Printers also need calibration because proofers and other digital printing devices can change output quality when the colorant or paper stock is changed. Calibration is not required for most input devices such as scanners and cameras, as these devices are generally self-calibrating.

Stands for cyan, magenta, yellow and black, which are the four process colours used in printing. They represent the subtractive colour model, where a combination of 100% of each component yields black and 0% of each yields white. Cyan, magenta, and yellow are the subtractive complements of red, green, and blue respectively.

This is the process of creating an ICC (International Color Consortium) profile that describes the unique colour characteristics of a device used to process your stock image. The device could be a monitor, scanner, colour printer, or a printing press.

This is defined as the creation of a temporary test use, rough layout or comprehensive rendering of a proposed work for client or internal company review, or testing. The image may not be used in any materials distributed or accessible to the public or in any final product or use, including, without limitation, any online or other electronic distribution system and may not be sold or sublicensed alone or as part of any product. The only exception in electronic transfer is that you may transmit comps digitally or electronically for review

This occurs in an RGB monitor, where red, green and blue signals all "converge" in one pixel. At full brightness, the RGB pixel in convergence would be white.

This is a proofing system that does not include the use of film. Data is sent to a printer and imaged directly onto a paper-based material. There are several limitations of a digital proof: 1) they do not use the film that will be used to produce plates, and thus are open to interpretation of the output device 2) A few of these devices print in the same dot pattern as is utilised in the printing process, and 3) The ink used in these printers is not representative of the inks used in the printing process and can show a vast colour range and density, which are not attainable on a printing press. Digital proofs are usually used where its costs a lot of money or takes a lot of time to run a wet proof.

When a stock image is looked at through a screen that converts it into dots of various sizes. When printed, the dots merge to give an illusion of continuous tone to the naked eye.

This is a file that describes how a particular device reproduces a stock image's colour. It does this by transferring the critical information that the devices need regarding the intended colour levels of the output. Generic profiles are created by the device manufacturer, who examines the colour characteristics of a group of the same devices under controlled conditions, and then uses this information to create a profile.

This is the process of laying out pages in a press form so that they will be in the correct order after the printed sheet is folded.

Stands for Joint Photographic Experts Group and is the most common compressed standard for high-resolution stock photos.

This is a short form of low resolution. If you use a lo-res stock image, it will result in low quality reproduction because of fewer number of dots or lines per inch as compared to a high-resolution image.

This is a signed release from the person/s depicted in a stock image, giving consent for his or her likeness to be used for commercial purposes as described in the release. It is your responsibility to ensure that you have the correct model releases for your license use and that you comply with the relevant local laws.Click here to know more about model releases.

ShotIndia’s images can be sold repeatedly to different clients. ‘Non-Exclusive Rights’ means that other people can buy the image you have chosen.

Low image types are perfect for the Web, presentations and other multimedia uses, while the Medium (17MB), High (47MB), and Super (99MB) ) image types are suitable for high-quality print reproduction.
