scanned art line with transparant background

[Anonymous]

Hi,

Could someone be so kind to explain me step by step how I can make a scanned line drawing transparent..?

I can insert the line drawing easily in sketchbook but i have no idea how to make the background transparent.

I've watch some YouTube tutorials but that didn't help me. 

I want to colour the line drawing in an other layer on top of it, so i can easily fill in faces/ shapes, now it doesnt
recognize these. It is possible to colour these in the line drawing itself but i don't want to do that.

I use the Android version on my samsung Tab S4.

Some help would be appreciated!

Maybe you should change the layer mode of your scanned lineart to "Multiply"?

Hi, thanks for your reply.

Setting the layer to multiply doesnt work either.

The layer above doesnt see the art line as separate lines and shapes. So if i want to colour

an object with the automatic fill bucket it fills the whole drawing. So i think i need to make the background transparent first to use this tool. The scanned art line drawing has a white background.  What i want is a layer with the line drawing (just black lines) and a second layer to colour the drawing. Perhaps this isn t possible in sketchbook?

By the way a total different question, Is it wise to draw the drawing by hand firts and than scan the drawing or is it better to draw directly in sketchbook?

I feel a bit uncomfortable with drawing digital lines but i love how the colouring works.

Can you send me your scan sketch?  You can export to .psd and email it to yourself.  Then you can attach it to this post.

Hi David,

Thanks for your help.
Hopefully you can explain how to colour on top of the line drawing in a new
layer.
Now it doesnt recognize shapes when i use the bucket tool. It colours the
whole drawing.

I have the psd file attached.

Personally i do it in several steps:

First i draw a sketch on a paper and make a photo with digital camera. After that i open it with Sketchbook, give some name and block. Next i create a new layer and draw the lines according paper sketch. The color i choose for digital lineart is usually black, the color of lines on paper is grey ( i use rough pencil). Sketchbook has a good tool for accurate lines - i don't know how to call it in English but it's near symmetry tool. Zooming makes the work easier. When it's ready i make first layer unvisible.

Here is the sample of ready art.
