Sorry, need help ASAP. I designed a book with 20 digital pencil illustrations. I have a hardware calibrated BenQ monitor. Sheridan (the Printer) specifies that for black only printing, all images should be converted to grayscale. Makes sense. They also specify the expected Dot Gain for uncoated stock on a Web Press is 25-27%. Ok cool. However, when I ask about grayscale profiles for 1) converting images to grayscale and 2) soft proofing the images on screen, they just keep answering that no profiles are needed for grayscale. To my knowledge, you cannot convert an image or even view an image without a profile. If a custom one is not selected, Photoshop will use the default profile. Which in my case is Dot Gain 20%. I don't know if I'm thinking about it all wrong, but here are my questions. PS, if you didn't guess yet, I have never printed a book interior in single color black only: What is the best way to convert sRGB illustrations to grayscale for offset web press printing on uncoated stock? I want to prevent the images from darkening too much and losing the fine tone/texture detail in my digital pencil drawings. I tried converting with Dot Gain 20%. It makes the images appear lighter on screen. I tried Dot Gain 25% and it make the images appear darker on screen than the 20% profile. Shouldn't the 25% profile appear lighter on screen than the 20% profile because it is compensating for more dot gain? The on screen effect is the opposite of what I expected. Are Dot Gain profiles even still used in a modern printing workflow? I read on a post here that using just the K channel in CMYK is better for modern workflows. For cover printing, when I asked about color printer profiles Sheridan recommended Coated FOGRA 39. On one of their documents they recommend GRACoL2006_Coated1v2.icc. And on another document for exporting to PDF they recommend U.S. WEB COAT (SWOP) v.2 if the document is not already setup for the correct color space. Are they trying to be confusing or are these profile so similar that it wouldn't matter a whole lot? In the end, I just need to know how to ensure that my illustrations will print nicely on uncoated paper. How can I do this. Is it possible to soft proof for this on screen.
