By saving the transfer curve, you can easily add the curve during file setup by using the Load button. This saves you from having to re-enter the information every time you want to include a transfer curve with your image. The gain corrections can be applied universally to all separations, or you can adjust channels individually. You have two options. This will work if you are printing with solvent-based inks.
Dot gain is almost the same for each color.
If you are a textile printer, or a graphics printer using UV inks, dot gain progressively increases as you lay more ink down on the substrate. So you'll need to adjust each channel separately. The additional gain comes from the increasing amount of ink already on the substrate. With textile printing, the increased gain is due to a larger volume of wet ink.
