Question

Line thickness in graphic tablets

Hi all

I'm an illustrator and new to graphics tablets. I've started with a Wacom tablet.

The main question I am confused with is how to choose the right line thickness for my drawing.

I used to draw my illustrations using pencils and ballpoint pens. Now after drawing I scan them open it in Photoshop and starting to draw with my graphic tablet.

So how to choose the right line thickness in order to get my desired thickness after printing.

When i start my drawing directly in Photoshop without any sketches, the problem is more serious, because i'v no idea that how the final line thickness will look. No monitor can show the line thickness as same as the thickness will be after printing.

thanks in advance

Hi Henrik (do I have that right?)  The process is generally referred to as 'inking' when it comes to digital drawing.  In fact a lot of people still uses and scan pencil drawings, and then ink over them in applications like Photoshop.  Because you can use multiple layers, the line thickness is a matter of personal choice, but try using a full hard round brush preset with size jitter set to Pen Pressure. 

Brush smoothing makes the process easier, and that has been available for a long time for Windows users via the third party add-on Lazy Nezumi Pro.  In fact, if you 'are' a Windows user, then Lazy Nezumi is a must have.  If you are a Mac user, then Photoshop introduced its own version of brush smoothing a couple of major version updates ago.  You will still find that it takes practice to place your line work exactly where you want it.  In my opinion, there is no such thing as too much practice for this.

A good exercise is to try and draw intersecting lines.  The way I like to do it is make a new layer, and 'Select All' (Ctrl A or Cmd A).  You then just need to hit the delete key to clear the screen ready for your next set of lines.

It's good that you have a Wacom tablet as they are the most reliable from our experience answering questions here.  I use the Express wheel on my Intuos 4 to adjust brush size.  I have the Express Wheel set so that it effectively toggles between brush size and rotating the canvas

But almost always hold down the R key to rotate the canvas.  Note I said 'Hold Down' as opposed to press.  This is one of Photoshop's Spring Loaded shortcuts, which means when released, it returns to whatever tool you were previous using.  Rotating the canvas is obviously the same as rotating a sheet of drawing paper, and a lot of people find this helpful.

BTW  I used to think that a Cintiq type tablet would help with line accuracy, but I have a Cintiq Companion 2, and don't find my line work is any better with it.

This is the official trailer (as it were) for Lazy Nezumi Pro

As well as brush smoothing, Lazy Nezumi has 30 plus presets which I find invaluable for drawing.  Vanishing Lines is my favourite. It lets you match a drawing's existing perspective.  Great for Photoshop composites.

Vanishing Lines workflow

Search Youtube for Photoshop Inking and you'll find a ton of advice.  We have a talented young lady here called Leslie Murray, (I would kill to have half her tallent!).  Leslie made this illustration for one of our posters who had to go into hospital, and it apparently cheered him up no end.

Hi Trevor

Thank you so much for your time and great reply.

Yes, I used to draw my works by pencil or any kind of pen scan and ink them using Photoshop or Sketchbook. Your answer was very helpful but my problem is still the same. How to choose the exact thickness as I've drawn on paper to have the same thickness in the final output?

I might be repeating what other posters have said, but depending on what printer you are using, and the paper size it uses, if I have that requirement I start with the relevant document size, so I use the Print tab in the New Document panel, and in my case, I would choose A4.

Looking at the Image Size for A4 I see that it is 21 centimeters wide and 2480 pixels,

so to print a 1mm line thickness = 2480/21 = 118 pixels

But why make it hard for ourselves? If we ignored the resolution when creating our new document, but instead used conveniently rounded pixel size. A bit of math shows that re-sampling our A4 image to 254 ppi, and that works out that 10 pixel brush will print 1mm line thickness

You are not going to see any difference in print quality with 254ppi instead of 300ppi

Hi

If you set your monitors actual resolution in Preferences >Units &Rulers >Screen resolution you can use View >Print Size to preview the width of your line as it will be printed at the current document resolution.

Preferences for screen resolution

I was just checking, and was interested to note that you can specify the width of Shape strokes in points, millimeters, or inches, which show correctly in View > Print Size, but Brushes can only be in pixels. Photoshop doesn't even convert; it will change the unit to pixels, but leave the number the same.
