Hi, I am halfway decent with Photoshop but in my line of work commonly come across an issue that I KNOW can be done easily with a couple of clicks but can't figure out how. I need to take a low-quality image (like the first one shown below, with some color) and turn it into as clean and high-res image as is possible, in black and white (will eventually be turned into a bitmap). I then send the bitmap for production of metal dies for printing. The second image is as far as I've been able to get towards that end. I started by taking the color image and upping the resolution to 1000 pixels to clean up the lines some. (1000 is also my personal standard so that everything is sized correctly--I know it's unnecessary but it's easy to remember). Then I went to "enhance" and clicked "convert to black and white" and turned the contrast all the way up. What I've ended up with is the second, black-and-white image attached. The problem is that what I've ended up with is true black lines that are crisp enough for my purposes, but some gray tones that "dirty up" the image. What I'd like to know is how to get from the original image to a cleaned-up final version with none of the gray blotches outside of the true black stuff. I imagine someone might be able to tell me a way to do what I want to do that doesn't involve the steps I've already taken, and I'd like you to know that I am certainly not married to my current process. Whatever is simplest and has a good outcome will be awesome. Thanks very much in advance for your help.
