CLIP STUDIO PAINT useful features : How to import traditional drawings and extract lines


Hello everyone. I am Caterina Rocchi. I am the principal of “Lucca Manga School” in Italy. This time I will introduce how to import and prepare a manga page drawn in traditional media and how to draw illustrations and manga, and make use of the many usefull features of CLIP STUDIO PAINT. Here I would like to introduce some convenient functions in CLIP STUDIO PAINT to polish manuscripts drawn with traditional media. First, let’s digitize a document drawn on paper with a scanner or a camera. Then, start CLIP STUDIO PAINT and open the new image file using [Open] in the [File] menu. To create a monochrome manuscript, change the “Expression color” of the document in the [Layer Property] palette to monochrome. Change the “Color threshold” and adjust how strongly the lines are shown. Press the black button of the “Change expression color” feature to replace the white part with transparency. If you are satisfied with how it looks, click the “Apply expression color of preview” button. That’s all you need to do to extract the lines for a monochrome page. If you want to use lines that have anti-aliasing or shading, instead of the monochrome binary, select the [Layer] menu … [New correction layer] and select [Brightness/Contrast] after you have loaded up the image. Use the “Brightness” and “Contrast” slider to adjust the paper color so that it looks white and the lines are not too weak. For this manuscript, the brightness is set to 38 and the contrast has a value of 70. Then I click [OK]. Select the [Layer] menu … [New correction layer] and choose [Level correction]. Move the node at the bottom of the graph and adjust it so the thickness of the lines is just right. Lastly, select the [Layer] menu and choose [Merge layers]. Since the background of the image is now white and layers below it will not be visible in this state, select the [Edit] menu and choose [Convert brightness to opacity]. This completes the extractions of lines from a drawing in color or gray-scale. From this state, select [New Layer] and add a white [Paper] layer to make the lines on the canvas more visible. Next I’ll show you how to erase dust and such, that might have been scanned in. Select the line drawing’s layer and turn on the “Border Effect” in the [Layer Property] palette. By changing the color of the border to a color that is easy to see, like red, you will immediately see where dust is left. Once you know where that dust is, use the “Remove dust” tool next. Under the [Correct line] tool you can find the [Remove dust] tool. Select the parts with dust as you would with the normal selection tool, to erase it easily. You can adjust to which degree dust is removed in the [Tool Property] palette, by adjusting the value for each manuscript accordingly. After removing the dust, simply turn off the border effect. And that completes the process.
