It is advised that some sharpening is required when sending images to press. I have been using Photoshop High Pass sharpening with Edge Mask mostly. Recently I have noticed that there is a sharpening option when exporting images from PS Lightroom. I wonder if there is any advantage in Lightroom sharpening compared to Photoshop Layer Blending Sharpening. I am asking this question from those who are experienced in offset printing.
