By now, you probably know that soft proofing is a valuable tool which allows you to simulate on your screen how colors and tones will print. It takes into consideration the whiteness of the paper and how in-gamut these tones are. Programs like Lightroom and Photoshop, which happen to be the two most used programs for soft proofing even provide you gamut warnings which show you if certain tones in your soft proof preview may run into limitations. In other words the printer might or might not be able to achieve those tones. There are plenty of tutorials on YouTube on how to soft proof and many of our customers do utilize soft proofing but it is something you cannot do halfway. Its an all or nothing process otherwise your example preview may not be accurate. Below are a three common mistakes we see when people soft proof.
Mistake # 1: Not properly calibrating your monitor
I want to start off by stating DO NOT use the calibration print we offer as a way to calibrate your monitor if you plan to soft proof. The calibration print you can get from us or from other color labs are good to give you a general sense of how tones print in comparison to your computer screen but no where accurate enough to accurately soft proof. Only a hardware device that can calibrate your monitor is going to achieve the accuracy needed.
Mistake # 2: Over-estimating the capability of low-end computer monitors/displays
Color labs will usually invest in very expensive displays that can achieve highly accurate renderings when viewing a soft proof. I don't want you to feel that you are cutting corners if you do not have a high end monitor or using something like a laptop but I know from experience when I use a lower end monitor to soft proof that once in a while it leaves me wondering if perhaps soft proofing was not as accurate as it should be. In this respect Adobe Lightroom has one-upped its cousin Photoshop or at least for now. Both programs offer gamut warning tools to show you if colors and tones are outside of the printers capability but Lightroom also has a monitor gamut warning option which helps to compensate by indicating if there are colors outside your computer screen capabilities . Because of this alone I think that Lightroom offers a superior soft proofing method.
Mistake # 3: Embedding ICC Profiles
Embedding the media profile is perhaps the biggest mistake. In Photoshop (or Lightroom) after you make your color adjustments in Soft Proof mode, you will want to save your image or at least a copy of the image you want to be printed. Make sure that when you save the image you DO NOT embed the media profile you used for soft proofing. This media profile is merely used to tell you how your image is going to look when it is printed so you can make appropriate adjustments. Instead save you image in a popular RGB format like AdobeRGB, sRGB or ProPhotoRGB. This way when the printing software prints the image it prints it with the adjustments made to look like it does on your screen. Embedding the profile takes it out of one of these popular RGB formats which the printer expects therefore leads to unpredictable results.
Adobe has a great video on soft proofing in Adobe Photoshop CC, the latest version. I would suggest checking it out below:
The only exception I think I have with this video is the suggestion is to use a colormetric rendering intent. Make sure if you print with us to select Perceptual so that you are more closely in-line to what our printers do.
