Hey Jerry, I don't know if it's the best way, (there's another method using channels...) but here's how I do it: Take my stitched artwork (I usually do 3 scans, overlap and line up using a 60% opacity on the layer - when it's in the right place, put it bk up to full and lay down a mask at the edge to feather the merge - Then flatten. I can go into more detail if you need on this) and then head to Image->Adjustments->Hue/Saturation (I'm assuming your in RGB mode for the next bit...) Now at the top drop down menu select Cyans and drop the saturation and raise the brighteness to max. Repeat this process for the Blues channel in the same drop down and voila - Blueline removed! Now just tweak your levels after converting to greyscale in the Image->Modes->Greyscale and you've got the inks. Always keen to hear if there are other ways of doing this though

Well, my trial for Photoshop is up, so I was wondering if anyone had a conversion to Blueline guide for the GIMP software, and Blueline elimination once it's scanned. Thanks!

That You Jerry? I usually scan in Greyscale at 600 dpi I open in Photoshop and convert to DuoTone 1 Go to IMAGE-MODE-DUOTONE 2 Set the TYPE to MONTONE 3 Then in the second box on line one I use the following settings H - 264 S - 20 B - 95 Then Save and Name it "Blueline". 4 Click "OK" and save as PDF. 5 Print it out, or take to Kinko's This looks insanely useful, but should that first value (H - 264) be 164 instead? w/ 264 I get a rich violet color, where 164 is a very pale cyan which seems much more likely. Looking forward to some trial prints at Kinko's tonight.
