Color Management

Color Management is so important to the high end digital workflow that it demands its own page altogether. If a workflow is not properly set up from a wholistic perspective – that is, with consideration of every step from input through display to output – your scans will never look right in any medium. Our color management strategy is broken down into two basic areas.

Joseph Holmes Color Spaces

For a more in-depth explanation of color gamut and the foundation behind his excellent products, you can read it in his own words here. ProScanNY is licensed to embed Mr. Holmes’ profiles in every scan we send out, for perfect color every time.

Color Gamut

When our eyes see a scene, we are perceiving a far greater spectrum of colors and tones than can be reproduced by any print or display. Therefore, the ‘gamut’ of available colors in the visible spectrum must be compressed into practical boundaries that our intended reproduction medium can manage. The resulting ‘color space’ can be represented via two or three dimensional tables demonstrating input versus output values. Common Gamuts are Adobe RGG 1998 – the graphics industry standard – or sRGB – which is reccomended for web based output. More recently, Adobe has introduced a much larger gamut – ProPhotoRGB, in response to expanded needs of modern imaging devices. In addition to these common gamuts, ProScanNY offers custom Gamuts designed by Joseph Holmes. We are licensed to embed these gamuts in our output files so that you can go direct from scan to print without doing a color space conversion, regardless of where you print.   Joseph’s spaces are specifically tailored to input medium and matched to output device. The advantage of this is that the more closely a gamut matches the actual range of the medium, the more precise control you have over your colors and contrast – you can push your image right to the limits without risking the out of gamut, blocked up zones or banding that so often plague digital output. We scan and embed Joseph’s color spaces by default, but if you desire any of the Adobe standards, or any other specific spaces, just ask!

We routinely recalibrate our equipment with top quality HCT targets for the best color available.

ICC Profiles

ICC profiles are the map that translates a color from one space or device to another. Accurate ICC profiles for every device in the system are critical in order to ensure consistent and accurate color reproduction throughout. Our scanners are profiled using top-quality, individually measured HutchColor targets .  This global color management solution ensures that output is consistent across all devices in the workflow.

Bit Depth

You may have read or heard a lot about bit depth in images. Bit depth is the measure of the amount of color gradations a single color channel can display. There is an excellent online tutorial available here. In practical terms, since printers and output devices can’t display beyond 8 bits anyhow, for many purposes an 8 bit scan will suffice. However, if the image will require manipulation in photoshop or you expect to shift its color or tone values significantly in post-processing, a 16 bit file will ensure that you have enough information to do this without degradation to image quality. Our default for all workflows is to always output 16 bit files in order to always record full image data. You can always go down later, but you can’t go back up!
