Sanning drawings Topic is solved

[trenino]

Hi all. I am wondering if there is a way to eliminate a blue line (or any other color) from scanned sketches. In order not to create a new layer with the cleaned up sketch, but to import the rough(blue) and the cleaned up (black) line from one drawing.

I know this can be done if the blue,red, etc is drawn with the TVPaint tools but not sure how it works with imported scans.

thanks

For traditional animation drawings which have a light blue or red colored pencil under-drawing, with black clean-up line the best way to eliminate the blue or red lines is to do that at the time of the scanning within the scanner interface settings. If you use a scanning software like VueScan you can scan in black & white mode and set it to drop out the blue channel or the red channel, so only the black lines will be scanned. The EpsonScan Professional scanner software also has this function.

This is what it looks like in the EpsonScan interface. Selecting the Red Channel would allow you to drop out all the red lines , or selecting the Blue Channel would allow you to drop out all the Blue lines on the drawing -

However , if you scan the drawings in color mode and the red or blue lines are on the scanned images you can eliminate them using the Black & White Convertor FX in the FX Stack. The Red , Green, Blue Channels in the Black & White Converter function similarly to how the "Channels" tab in Photoshop functions.

1.) In this example , the scaanned animation drawing has red under-drawing , with black graphite clean-up lines:



2.) Here is the scan imported into TVPaint with the red under-drawing still showing :

(this shows the old TVPaint 10 interface , but the function is exactly the same in TVPaint 11)

3.) Now using the FX Stack > Color > Black & White Converter , change the Red channel value to 255 , Green channel and Blue channel value to 0 . This removes the red lines . (if the under-drawing color is in Blue pencil then change the Blue channel to 255 , and the Green channel and Red channel to 0 ) .







After removing the red lines , run the Scan Cleaner FX as usual to strip out the white pixels and leave only the black pixels, so the drawing is transparent and may be colored.
