Message: <blockquote data-quote="CNS" data-source="post: 723423" data-attributes="member: 10669">Photoshop answerTry this out:- scan image at at least 300 ppi resolution.- in Photoshop, increase the image's resolution considerably- I use 800 ppi- the higher the better.- change the image MODE to bitmap. This will remove all grays leaving only black and white. Having the high resolution helps prevent a lot of jagged edges that come from pure black and white. Up close the edges will appear jagged but when printed or viewed at print size that effect is minimized. If you really want a more anti-aliased effect try a little blurring-convert back to grayscale MODE.-reduce the resolution back to 300 ppi. 300 ppi is acceptable for printed material.-now you should have a high contrast image- no grays.For coloring:-Change to RGB mode- if you will print it, select CMYK PREVIEW for a more accurate representation of what will print. You can use CMYK mode but the RGB mode results in a smaller file size and more vibrant color for "computer screen only" images-SELECT ALL and COPY-in the channels palette, creat a new channel and PASTE. This creates an alpha channel, this step helps in separating the black line from the white background-DESELECT ALL-command(MAC) click the new channel (I don't know what the PC version would be but hold the cursor over the channel name and press the command control, etc. keys until a little marquee appears near the cursor). This selects only the black artwork.-Click the RGB channel-this is to make sure you aren't working on the new alpha channel. The RGB channel should be highlighted.-PASTE- a new layer should appear containing only the black artwork with no white.-Change this layer's mode to MULTIPY- this will reduce any fringes that might appear.-Work in the background layer. Now you can add color in the background layer and not obliterate your black borders since they are isolated in their own layer.-To pick areas to be colored you can use the magic wand to make selections in the black line layer or the alpha channel. Make your selections in the black and white layer or channel but always make sure you are working in the RGB channel and Background layer when coloring. GROW the selection a little to help reduce fringes.-If you have made an area selection that you want to keep, choose SAVE SELECTION this will create a new alpha channel that you can command click whenever you want to activate that area selection again. These channels can also be edited: just select the channel view icon (the eye next to the channel name) the channel should show up in a color, probably red- then highlight the channel name and begin painting or erasing similar to quick mask mode. -the most important bit of advice I can give is always save your work and save it often.-Again, when switching between channels and layers like this it's easy to make mistakes. Always make sure you are working in the Background layer and RGB channel when coloring. I hope this helps. Right now this might look like a lot, but the more you do it the faster it gets and I'm sure it will get you the results you want every time. This is similar to the way most professionals do this kind of work.</blockquote>
