You can even select a particular area and apply a different threshold there. Choose Threshold from the options, and adjust your threshold as often as you wish. If you want to use an Adjustment Layer, go to the Layers Menu, and click the black-and-white cookie icon on the bottom. It allows you to revisit your choice of threshold as many times as you need to to get it right. But in many cases we find that using a Level Adjustment Layer to adjusting the threshold is a good course of action. The instructions above are written for making the threshold adjustment directly on the work. Zoom in on dense cross-hatching and other problem areas as testing spots. Once you have your threshold level just right, click OK to accept it. You might have to experiment with this a few times before you get it right. Note that what you’re seeing now is an approximation of what the filter will do, and that the results may vary. If you have very dark, dense art, or lots of grubbiness from over-penciling or using your art as a coaster, you may need to use a lower number. However, if you have used dry brush or inked lightly, or your inking has grayed out a lot from erasing pencils, you may need to use a higher threshold level.

Generally, setting the arrow around 100 to 115 works well for clean black-and- white work. You will see that the higher the number, the darker your art looks. So slide the little arrow to where your art looks nice and clean. At the default, every gray darker than 128 will go black, and lighter will go white. Setting the threshold means deciding where exactly in the spectrum of 256 available grays you want to make your cutoff of black from white.Go to IMAGE > ADJUSTMENTS > THRESHOLD and the following dialogue window will open: If your linework in straight up black and white, with only line-based texture and tone (like stippling and hatching) and not a lot of whiteout corrections and pencil traces, you might be able to save yourself time by just setting the threshold, converting to bitmap, and making corrections.Make sure you do this before any editing. Go to Image > Image Size and size up the image to 1200 dpi.The one you choose will have a lot to do with the qualities of the art itself (are you using drybrush? Lots of corrections?), and the destination (are you planning to color? using what method?) Here, we’re going to go over two methods, starting with the most basic approach to prepping straightforward black-and-white linework for print, using the Threshold tool. There are many ways to approach cleaning up your image and preparing it for print. Right? If that’s not what you have, go back and check the scanning quickguide. When we left off, we had a scanned and merged grayscale, 600 dpi, TIFF image. Quickguides: scan clean-up for black-and-white linework
