More than 20 tips and tricks on wide-format color management from seasoned experts
19. Photoshop for Image Assessment
Learn how to use Adobe Photoshop tools such as “Levels” to judge a file’s quality and ensure that scans and capture files are being made correctly and when moved, re-saved or edited, that the data stays intact. We recommend users retain full range of tone and color as long as possible in the process to respect the original art—if that’s the desired look. Since we all know that printing is improving by leaps and bounds, it’s inadvisable to discard image data (for example, by reducing saturation or converting to a small colorspace) just because an image is destined for a low-quality publication or print process. Make a copy first, save the original.

20. Inkjet Gamut Limitations
Gamut limitations in inkjet output can sometimes surprise people. Many assume that the inkjet gamut is always larger than a typical printing press (such as shown with a Gracol profile). While many inkjets print more saturated mid-tone colors, when it comes to shadow colors they may not be able to precisely reproduce the darker browns and greens found in many images. This can result in unexpected color shifts and sharp transitions. To take advantage of inkjet’s capabilities, ask for files in RGB spaces like Adobe RGB, and to maximize dark color gamut, choose your media carefully and convert color to your custom profiles judiciously.

21. Hire Some Help
A consultant can train and quickly get you up to speed. Just make sure you outline your expectations and what you need to accomplish. Very often they can get you there quickly—and teach you things that would take weeks or months to learn on your own.
—Ron Ellis, Ron Ellis Consulting
22. Archiving the Master Image
Where space permits, archive your raw files or high-bit (16-bit) originals—and also your full-size 16- or 8-bit layered .psd image files. At output time, working on a flattened duplicate, optimize your output files to suit the print destination and—importantly—work on your compatibility with the others in the image chain—be they photographers, designers, agencies, or print houses.
