Hi! I use Ramon’s SK2 sketch brush mostly, but today I feel like inking; the sketch brush looks too grainy (it’s not). So I’m using Basic-5 Size brush and I find the result is satisfying, except…
The issue is at the beginning of the pen pressure, where the Pixel brush engine starts the line. I cannot get my small, light lines smooth - by smooth, I mean without aliased edges.
After 2 hours of experimentation (encouraged by Ramon’s excellent brush videos, TYSM!), I finally discovered my problem, I think - the first node on the Pen Pressure graph.
I saved this 2048x2048 canvas in PNG with ‘1’ compression (hopefully it’s a pixel-by-pixel recreation??). I’m not versed in image formats, yet.
Okay, to the questions! Am I missing something? Do y’all have aliased edges? Do you see what I’m seeing? Is it my monitor (24" 1920x1080 ~92dpi)? Is everyone using a 10000x10000 px canvas and 200px size brushes? Is it my Huion tablet? (Inspiroy 2L, Pentech 3.0). Another brush engine? A different brush?
I don’t normally obsess over the pen touch and line quality, but today’s the day! I will likely settle with 5% for the first node and get on with it until this bugs me again.
All .png images are ‘pixel-by-pixel recreations’. The compression parameter affects the file size and how long it takes to compress the image and then, later, decompress the file.
That would probably not be noticed on a modern PC, unless you had a very large highly compressed .png file.
Looking at your sample images, if a line width gets very small then you will notice the effects of it being made from individual pixels, especially if you zoom in.
In the Brush Editor’s Brushtip options, you could try disabling Anti-alias but that may not give a ‘nice’ effect.
For your workaround method with the brush pressure transfer curve adjustment, I assume it’s the Size you’ve modified, not the Flow or Strength? (You didn’t say.)
You might want to try all those possibilities but fine and detailed painting parameter modification is not my area so I’m just guessing.
If you want to do this a lot, you may find it’s easier and much less work to make a similar modification to the Input Pressure Global curve which can be found at
Settings → Configure Krita → Tablet settings.
That will affect the apparent behaviour of all brush presets but it’s quick and easy to undo that single global modification compared to tweaking the details of individual brush preset parameters.
Sad truth is that you always get pixslated edges when things are small or zoom is large. That’s just how the raster image world works. If you don’t want that you have too use vectors in a vector drawing program but even then. As soon as you export it to a raster image format like PNG: BAM! Pixels again.
