I have to make a professional project for my illustration exam at the fine arts academy i attend, this project implies high quality works for printing and i decided to draw everything in digital with CSP but i have a problem with resolution of the canvas.

Usually i work with 1200 dpi (crazy, i know) and with large pixel canvas such as 1200 × 1500 px but the quality is always awful, like i can see every single pixel when i zoom (something that with the comic format page option doesn't happen). I'm planning of making this illustrations on A4 size but i don't know how many pixels would be that format, neither the right resolution i should work with in order to not see low quality pixels all over the page.
Any help? :sob:

YES, when i zoom on one line looks like the "with anti-alias" one!
If that's the problem where can i change the setting?

Try to increase the size of the canvas, 1200 x 1500 px isn't really large.
If you want to work on a A4 with a 1200 dpi resolution, you have to go in "edit", "change image resolution", and set the width at 8.3 in and the height at 11.7 in.

The size of a 1200 dpi A4 should be 9921x14031 px.

I'm not sure the dpi resolution is that relevant when you work digitally, usually a high quality file made to be printed is 600 dpi though.

I agree that 600 dpi should be enough for a high quality print, sometimes I use just 300 dpi :sweat_smile:

Anyway, you can also set up the size and resolution when you make a new file and it will adjust to the right quantity of pixels :3

@Zooplankton is right. If you print 1200x1500 at 1200 dpi (dots per inch) it would be 1 inch wide when printed at full resolution.

Instead, if planning to print, as mentioned, choose A4 size in the new canvas window and set to 300 or 600 for a truly HQ print.

I work at a minimum on canvases that are 2500 wide just to make digital art look better because there are more pixels available to support the anti-aliasing I want for smooth linework.

Edit: the reason you can see all the pixels when you zoom in is because the canvas size is very small. Think of it like a resolution of videos. 480 p is only 480pixels wide. 1080p is 1080 pixels wide. Because it has more pixels it can handle sharper images cause it has more pixels to create the variety of hue needed to trick our eyes into seeing better clarity.

In-between edit2: When working on art we often need to work on larger canvases to maintain the fidelity of the art. Sizing down keeps more details than sizing up. When sizing up the software has to guess and make new pixels to fill in the spaces of the original work where as when sizing down it just has to remove pixels for a tighter image.

Think of DPI where Dots = Pixels. Cause computer screens are made of tiny squares of light where as printers print in tiny dots of ink, hence 'dots per inch'.

Thanks to all for the very useful answers!
Though now i need to ask this too: if you're posting your webcomin on Webtoon (where the largest page you can post is 800 x 1200 px) which resolution works the best? Cause i have the same problem there too :sob:

I work on a canvas that's 3x as large as the Tapas limits (940 x 4000; so my canvas is like 2820x12000); then Clip has this really useful function where when you export to jpg or png (As opposed to Save-As; you can batch export a bunch of files if you have the CLIP files open)., in the window that pops up you can actually set the pixel size and it'll automatically resize it down for you when it saves as a jpeg, keeping the original size of your CLIP file intact.

This ensures my art stays sharp. The only thing to keep in mind is to always zoom out and ensure your font is large enough on your original canvas so that when it's zoomed out to phone screen size you can still read it.

Oh shoot. I feel like an idiot, I didn't even throughly read through OP's canvas size. I just saw 1200 dpi and I automatically thought it was a super big canvas. welp, there's the problem. MY BAD

Oh snap just realized in my written note i wrote down wrong dimensions: I mean 1600 x 2400 cause that's double 800 x 1200. my bad. But yeah, hope it helps ^^

I'm currently working on 300dpi on 1200 x 11520 px then resize it when uploading. I'm tbh used to working on 300dpi so I just keep that resolution constant.

Also for print 300/600dpi is decent enough, you just need to adjust your canvas size like instead of working on 1200dpi 1200 x 1500px work on 600 dpi 2400 x 3000 px or more. Btw, A4 at 600dpi is 4961 x 7016 px.
