Take color management to the next level

Soft-proofing is an on-screen simulation of how your image will look when output to an inkjet printer, substrate and ink combination or an RGB printer like the lightJet. It is based on an output profile of that device made especially for a that substrate and ink combination. A calibrated monitor is crucial for viewing color accurately and soft-proofing can take your images and color control to the next level. A printer can not reproduce the entire range of colors that are viewable on a monitor, these are known as out of gamut colors. Each printer, paper, ink combination has its own gamut or range of reproducible colors. There may also be a shift in color balance from what you see on your monitor to the print. If you’re sending images or a design project to a printer for output on their LightJet or large format printer, the need for proof prints can be minimized with soft-proofing and you can identify what colors may need a little attention. To soft-proof your image in Photoshop, select View > Proof Setup > Custom. takecolormanagementtothene-choose-soft1 The Proof Setup dialog box will pop up, in the first drop down select the profile for the output you’ll be using. You can request this from your printer or photo lab. Next, select a rendering intent. These are the methods by which out-of-gamut colors are mapped from the working space to the gamut of the printer, paper and ink. Perceptual works well for most images especially if there are many out-of-gamut colors. Relative Colorimetric can be better choice if your image doesn’t have any colors that are out-of-gamut for the intended output. Meaning there is less interpolation in the mapping of color to the output device, where as Perceptual there may be more interpolation in mapping colors, attempting to preserve the relationship of colors inside and outside the output gamut. Black Point Compensation should be checked, this ensures shadow detail will be maintained in the output gamut. takecolormanagementtothene-choose-soft2 The Simulate Paper Color and Black Ink check boxes add a simulation of the whites and blacks of the profiled paper and ink. When a printer profile is made the color of the paper is one of the factors in building the profile, because the spectrophotometer is reading the combination of the ink, and the paper below it. These can be helpful if you are printing on off white or tinted substrates. When you click OK, you will see a simulation of the image printed through your output profile. To toggle between the proof simulation and the normal view press Ctrl-Y. Soft proofing can be a very valuable tool when preparing images for your trade show exhibit, POP poster or décor project. Feel free to email with any questions or to request one of our output profiles. Paolo DeSanctis Graphics Production
