Threshold adjustment for analog line drawing

Even the line drawing is drawn in analog, and the finishing and correction are taken care of by Crysta.
If you convert the image scanned in gray mode to monochrome with Crysta and adjust the threshold value,
・ If you set the threshold value so high that the line does not disappear according to the thin part of the line, the part drawn in Kakeami style that does not become solid becomes solid.
-If you set a low threshold value that does not become solid, thin lines will disappear.
In analog-drawn manuscripts and gray-scanned images, both thin lines and black-painted images that are not solid can be seen normally ...
I'm trying to make the best use of both by subtly changing the threshold for each frame, but there are still some parts that disappear.
Is there a way to solve this?
I'm in trouble, thank you.

2 years agoIs it in the state of adjusting with the layer property?
Try with [Alpha Threshold] instead of [Color Threshold].

2 years agoThe inked line arts read in grayscale are not all black, but have different "density". In particular, the ink tends to be thin in the thin line drawing portion.
Before executing the binarization of the line drawing, it is necessary to take some measures such as raising the "light density line drawing" part to black by level correction of the color tone correction layer. If possible, drop the "darkness" of the read line drawing part in grayscale and compare. If there is a difference in density, it is possible to combine color tone correction to perform binarization closer to the image.
